Hawke's Bay

9:20pm: There is a boil drinking water notice for private domestic water ie. bore water. There is a potential contamination of ground water from flooding. Civil Defence says it is unable to test all bores at this time.

A boil drinking water notice is also in place for central Hawke's Bay. Hastings and Napier water is safe to drink.

8:56pm: The Telecommunications Forum says there's been good progress in mobile phone coverage in Hawke's Bay. It represents phone networks Spark, 2degrees and Vodafone, as well as internet providers like Chorus.

Hastings is now up to 90 percent coverage and Napier is expected to reach 50 percent tonight.

Chief executive Paul Brislen says the networks brought in mobile cellsites on wheels to improve coverage. Mobile coverage will keep growing as the electricity supply is reconnected, he says. In the meantime, networks are using generators and satellite units to restore services.

8:51pm: The Unison lines company says it hoping to get power to more Hastings homes tomorrow which will help with getting more Napier homes back on on Saturday. About 32,000 households in the city don't have electricity. A power cut at the only Napier service station on Unison supply is being fixed and the petrol pumps will be operating again tomorrow, it says.

8:39pm: Hawke's Bay Civil Defence says people who rely on a CPAP machine and have no power can charge this at Wellesley Medical Centre or alternatively at the Centennial Hall Civil Defence Centre.

8:22pm: SH2 Napier-Hastings Expressway is open from the roundabout at the intersection of Pakowhai Road and the Whakatu Arterial Link, north to Napier. It is open for emergency vehicles and essential travel. North and south-bound lanes are open.

SH51, the coastal road between Napier and Hastings, is also open to emergency services and critical workers. Motorists will be asked for identification before being able to travel through.

8:05pm: Sarah Grant says the farming community of Dartmoor is running low on emergency supplies like fuel and food for locals and animals. She says they only have enough food left to last them a week and she has sent the list of needs to the authorities, and expects they'll respond hastily.

7.20pm: The Government has injected an initial $2 million into the local disaster relief funds in both Tairāwhiti and Hawke's Bay.

The Civil Defence Minister Kieran McAnulty says it is too early to know the full cost of the damage wrought by Cyclone Gabrielle - and he is anticipating more requests for support.

He says the Government is commited to supporting communities in need.

Mr McAnulty was in Tairāwhiti with the prime minister today - and described the scenes as gut wrenching.

7.15pm: Police say Cyclone Gabrielle's fifth victim is a 60-year-old man whose body was recovered from floodwaters in Gisborne

Three of the other victims were in Hawke's Bay and a volunteer firefighter was killed in a slip in Muriwai.

Police say while the worst of the weather may have passed, Hawke's Bay and Tairāwhiti still face significant and potentially lfie-threatening challenges.

They are focussed on finding missing people and reaching those isolated by floodwaters.

This afternoon, three-thousand-544 people have been registered with police as uncontactable.

Police say many of these are likely to be multiple reports about the same people.

7pm: Hawke's Bay residents are again being warned not to drive through floodwaters after a woman and two children were rescued from a vehicle today, two days on from the worst of Cyclone Garbrielle.

Swift water rescue specialist Michael Harvey says the trio got into trouble on a back road between Napier and Hastings.

He says some people are still taking unnecessary risks.

"I think people are desperate to get places and willing to drive through the flood waters, but the depth of the water gets up quickly and surprises them."

Michael Harvey says the children were about four or five years old.

"They were in good condition but the children were pretty upset and quite happy to be recovered from their vehicle."

He says the message is clear.

"Stay out of the flood waters, it's not worth it. Not worth driving through it."

6.30pm: Unison lines company says it is working on a solution to get power to more Hastings homes tomorrow. It says this will help it with getting more Napier homes back on on Saturday. As for a power cut at the only service station in Napier on Unison supply, it says it is a voltage stability problem technicians are currently working on and the power to fuel pumps will be back tomorrow.

6.15pm: Hawke's Bay Civil Defence controller Ian Macdonald said progress was being made on restoring electricity to flood-hit Napier, though most of the city is still disconnected. He said generators have been installed to supply the CBD, supermarkets and fuel stations.

Transpower earlier said water at the substation, located near the Tutaekuri River, reached up to 1.5m high and caused "extensive" damage.

6.pm: Civil Defence says it has no more room at the Hastings Sports Centre for donated items.

It says the community has been very generous in helping people displaced by the cyclone, but it cannot take any more donations at the moment, until it has a better idea of what is needed.

6pm: Numbers of search and rescue personnel will be boosted by about a third over the next two days, as they try to check every property where people may still be stranded.

USAR team leader Ken Cooper says the 35 newcommers will take his team to about 100-strong and allow them to make a significant push.

Staff are going door to door in priority areas near main waterways, but most rescues are now from tip-offs by the public, Cooper says.

He says the return of patchy communciations has meant people are calling for help, while family members are heading into the Napier Fire Station to alert emergency services.

5.35pm: Te Whatu Ora says urgent medical supplies are being flown from Auckland to Tairāwhiti and Hawke's Bay.

They include medical oxygen, chemotherapy medication, pharmaceuticals, medical nutritional supplies and blood products.

A Defence Force Hercules C-130 is delivering them to Napier and Gisborne.

National Incident Coordinator for Te Whatu Ora, Matt Carey, says the normal supply chain for medical facilities is badly affected and deliveries will continue by air, and possibly by sea, until the roads can be used again.

5.30pm: The road between Napier and Hastings has reopened to emergency services and critical workers.

Waitangi Bridge on State Highway 51 had to close earlier today ahead of a safety assessment, cutting access.

The highway will be under temporary speed limits and is reduced to a single lane.

Waka Kotahi says it's vital emergency services and essential workers are given priority so people will be asked for identification before being able to continue.

It's the sole link connecting Napier and Hastings.

Work is underway to clear debris on the State Highway 2 Napier to Hastings Expressway.

5.00pm: Rescues are still continuing in flood-stricken Hawke's Bay with about 40 more people pulled to safety by search and rescue teams going door to door.

Team leader Urban Search Rescue, Ken Cooper, says the return of patchy cell phone coverage means stranded people are calling friends and family for help.

His team has been busy all day using Surf Lifesaving and Fire and Emergency boats to rescue in the main vulnerable elderly people.

Another 30 USAR staff are expected in the region tomorrow, Cooper says. That will bring his team up to 100-strong as they attempt to clear all the affected area.

4.46pm: Hawke's Bay Civil Defence is worried about misinformation and says no dam has burst and no evacuation has been ordered for Bridge Pā.

It says water has reportedly been observed rising but no water is coming in from the Ngaruroro River, and the rising water is probably due to a downstream blockage which teams are investigating.

4.27pm: MetService says severe thunderstorms are moving northeast and expected to be accompanied by torrential rain. A severe thunderstom watch remains in force for Bay of Plenty, Rotorua, Taupō, Gisborne and Hawke's Bay.

The thunderstorms are expected around Rotorua, Waiotapu, Waikite Valley, Waireka and Guthrie at 4.37pm; and near Rotorua, Waiotapu, Waikite Valley, Lake Tarawera, Waireka and Guthrie at 5.07pm.

4.19pm: The Central Hawke's Bay District Council says businesses can open if they can operate safely without excessive use of the town water supply.

Level Four water restrictions are in force throughout Waipawa, Ōtāne and Waipukurau and a boil notice is in place. The council says businesses that cannot open without impacting the water supply should refrain from trading. Some residents still do not have town water supplies to their home.

4.17pm: One woman is operating a make-shift internet cafe out of her caravan to connect the isolated Hawke's Bay community of Dartmoor with their families.

Sarah Grant says her Starlink satellite internet has been a saving grace for worried friends and family and she is on social media informing them of their loved ones' safety.

4.12pm: Power has been restored to nearly all of Taupō and Rotorua but more than 37,000 Hawke's Bay homes are still without electricity.

Unison power company says only limited supply is avaliable from the flood damaged Redclyffe substation. People who are connected in the area are urged to conserve power by turning off air-conditioning, put devices on standby, turn off unneeded lighting and any high consumption devices.

Unison says people should disregard estimated times for power to be restored on its website as this is based on normal working conditions. Those without power should prepare to remain so for an extended period.

The company says work is progressing to bypass Redclyffe through to Transpower's Whakatu substation to return power to the remaining parts of Hastings and begin restoring parts of Napier.

4.06pm: Residents in the Napier suburb of Taradale are clearing silt from drains ahead of more rain. They were forced to evacuate after the Tūtaekurī River and Ngaruroro River breached its stopbanks on Tuesday. Silt remains strewn across properties.

4.03pm: A Hastings catering company is giving out 150 meals to people in nearby communities today.

Tom Van Dijk says his company, Barbeque Gourmet, is distributing pasta meals for residents who are still without power in Te Awamanga, Haumoana and Clive and will continue to do so until the food runs out.

4.01pm: Dozens of people are gathering near Pak'nSave in central Napier to make use of the wi-fi. The town remains without power, internet access and phone networks remain patchy.

3.47pm: An aid convoy to coastal settlements on damaged roads out of Dannevirke has found everyone safe and well. Five 4WDs have got to Herbertville and two to Ākito with medical supplies and other help.

Deputy mayor Erana Peeti-Webber says the locals have water, food and the power came back on last night. Building inspectors in the crews have red-stickered some buildings from cyclone damage, including the Herbertville pub. The local motorcamp had shifted its five permanent residents to high ground and set up an alternative water supply.

3.28pm: HMNZS Te Mana is travelling to Hawke's Bay in the coming days with supplies and a 25-person emergency response team.

A logistics support team of 100 people and 30 vehicles (Unimog and Pinzgauer) have already been sent to Hawke's Bay; the logistics team will include specialists in catering, medical, transport, fuel and vehicle repair.

An NH90 helicopter has moved NZDF military satellite communications staff to Wairoa and will also be available for moving emergency supplies, such as food, around the region.

2.51pm: Hawke's Bay Civil Defence says people without power and EFTPOS can access cash at some ANZ ATMs. It says the ATM at Napier's Countdown on Munroe and Station Streets is fully operational.

2.33pm: The Waitangi Bridge at Awatoto in the Hawkes Bay is open to regular traffic, but emergency vehicles and supply trucks will be prioritised.

Hawke's Bay Regional Council says delays in crossing the bridge are likely due to it being the only open Napier-Hastings connection.

Hastings has at least six petrol stations open, while access to fuel is limited in Napier. Fuel supplies in Napier are expected to be restocked in the next two days and more petrol stations will be connected to generators.

2.27pm: Refuge and Migrant Services says the 12 RSE workers unaccounted for in Hawke's Bay earlier today have been located. General Manager Fiona Whiteridge says the workers are being cared for.

2.18pm: Waka Kotahi/The Transport Agency hopes to reopen SH2 between Hastings and Napier this evening after checks on the Ngaruroro River bridge - until then there is no way through.

Another road, SH51 nearer the coast, reopened briefly last night and was busy this morning, according to motorists - but it shut again earlier today for checks on the bridge at Clive. Waka Kotahi said those Clive bridge checks may have to wait till low tide tomorrow.

1.10pm: Hawke's Bay Civil Defence is running the following civil defence centres: NAPIER: Centennial Hall, Vigor Brown Street, HASTINGS: Hastings Sports Centre, Railway Road, Flaxmere Community Centre, Swansea Road; WAIPAWA: CHB Municipal Theatre, Kenilworth Street.

12.20pm: The Clive Bridge on SH51 between Napier and Hastings has been closed for a safety assessment.

12.05pm: The fuel situation is improving, and generators have been given to some fuel stations. One at the BP distribution point means the fuel at that facility can be distributed to fuel stations, which is happening now.

12pm: Officials are planning to get an 0800 number set up but with the problems with connectivity at the moment it is not the highest priority.

11.50am: Napier port has reported minimal damage to its infrastructure. Shipping will resume on Friday following safety assessments.

11.06am: The national power grid operator says it has made changes to get enough power to Hawke's Bay and Gisborne for 90,000 households. Transpower says a check by chopper shows a pylon tower has fallen between Redclyffe and the Fernhill substations next to the Ngaruroro river The agency says this has limited impacts and is not a safety threat.

11.03am: The Waitangi Bridge at Awatoto in the Hawke's Bay is open to regular traffic, but emergency vehicles and supply trucks will be prioritised. Hawke's Bay Regional Council says delays in crossing the bridge are likely due to it being the only open Napier to Hastings connection.

It says people are expected to travel into Hastings because it has at least six petrol stations open, while access to fuel is limited in Napier. Fuel supplies in Napier are expected to be restocked in the next two days and more petrol stations will be connected to generators.

10.58am: Of about 40,000 homes without power across Hawke's Bay, almost 32,000 of those are in and around Napier. Unison said electricity was being progressively restored to them. The regional council had said online that "the power outage in Napier is expected to be at least two weeks." But Unison spokesperson Danny Gough said "two weeks would be the worst-case scenario".

10.52am: A generator supplier based in the South Island is sending generators up to flood affected regions in the North Island. QPower Director Don Biss said several generators would be shipped on Thursday to help power Hawke's Bay businesses.

10.46am: Elective surgeries, endoscopy services, and outpatient appointments in some places are cancelled in Hawke's Bay for Thursday and Friday.

Te Whatu Ora says affected patients are being contacted and offered a telehealth appointment or rebooked as soon as possible.

Outpatient appointments in Napier, Hastings, Wairoa and Central Hawke's Bay are cancelled.

Three acute theatres and radiology are operating at Hawke's Bay Hospital in Hastings, and urgent clinics are open in Napier and Hastings.

Te Whatu Ora understands people are worried about the whereabouts of loved ones, however, people should not to come into the Hawke's Bay Emergency Department unless seeking urgent medical care.

Te Whatu Ora interim national medical director Pete Watson told Morning Report because not all staff could be at the hospital due to the weather-related problems, such as transportation, they were having to reduce non-urgent care and prioritise urgent care.

They were working with agencies to ensure they continue receiving the required supplies, such as oxygen supply, blood supply and medical supplies, he said.

Some primary care services have also been impacted by the weather, but if people in those areas need medical care, they can make their way to evacuation centres where they will be supported to go to a medical centre or the hospital.

8.36am: MetService has issued a severe thunderstorm watch for Hawkes Bay from 3pm - 10pm on Thursday. A few of the thunderstorms could be severe about the ranges of Hawke's Bay with localised downpours of 25mm to 40mm per hour and hail.

8.26am: Countdown's Gisborne, Carlyle (Napier) and Napier supermarkets are still closed, but managing director Spencer Sonn told RNZ they were hoping to reopen the Napier and Carlyle supermarkets later on Thursday.

8.20am: Two New World supermarkets, Onekawa (Napier) and Havelock North, were closed on Thursday morning and eight Four Squares in Hawke's Bay were not able to open. Foodstuffs is using a helicopter to get produce to Wairoa, and hopes to have road access there on Friday.

7.54am: Napier City Council says water in the taps is safe to drink and it's important to stay hydrated but use water wisely. Don't rush to flush, limit showering, do the dishes by hand, wash clothes by hand. Don't wash down paving and driveways.

7.15am: Hawke's Bay Civil Defence update:

  • Power: The power outage in Napier is expected to be at least two weeks. More details on this to come. Emergency power has been provided for Wellesley Road Medical Centre, Countdown, Caltex Napier
  • Water: NCC has connected generators to drinking water supplies, this has assisted with pressure. Napier urges its residents to conserve water while this temporary fix in place. Napier's wastewater treatment plant is discharging untreated sewage through the outfall to sea, residents are urged to not consume kai moana. It is unknown when the treatment plant will be repaired - to make an assessement we need flood waters to recede and power to be restored. Napier City Council urges residents to only flush toilets when necessary.
  • Roading: SH51 Clive - Waitangi Bridge is open to the public, however expect delays, this enables movement between the cities and logistics to Napier. Caution is advised due to road conditions and heavy volumes of traffic.The roading networks north of Napier have been severely compromised with multiple slips and bridge wash outs, assessments have yet to be completed on all of these roads.South of SH2 is open but caution is urged due to flood damage.There are a number of other roads now open with flood damage - please travel with caution.
  • Fuel: Fuel supplies have been secured and local stock will be replenished when the port opens - at this stage on Friday 17 February.
  • Food: There is no need to panic buy as roads are opening and supermarkets are being restocked as are other essential services.

6.49am A rapid relief team reached Wairoa on Wednesday night with 500 food packages to hand out.

6.32am Hawke's Bay Civil Defence said SH51 between Napier and Clive reopened at 8pm Wednesday following assessment by engineers.

6.20am HMNZS Te Mana will sail to Napier today to supply Wairoa with water and other essential supplies.

Gisborne / Tairāwhiti

7:55pm: Tairāwhiti Civil Defence controller Ben Green says a large team is working hard to reach isolated households to establish contact with them. When roads are impassable, staff have flown into some areas to reach whānau, he says.

7:47pm: The navy ship HMNZS Manawanui has dropped off food and water at Tokomaru Bay today - and will carry on to Tolaga Bay - before arriving in Gisborne tomorrow.

7:36pm: Gisborne District Council says all GP centres and pharmacies are opening 9am to 4pm. All appointments have been cancelled and doctors are seeing walk-in patients - the most urgent cases will get help first. Health workers are also helping out at marae and welfare centres.

The council says pregnant people needing urgent care should go to the hospital.

7.20pm: The Government has injected an initial $2 million into the local disaster relief funds in both Tairāwhiti and Hawke's Bay.

The Civil Defence Minister Kieran McAnulty says it is too early to know the full cost of the damage wrought by Cyclone Gabrielle - and he is anticipating more requests for support.

He says the Government is commited to supporting communities in need.

Mr McAnulty was in Tairāwhiti with the prime minister today - and described the scenes as gut wrenching.

7pm: Police say Cyclone Gabrielle's fifth victim is a 60-year-old man whose body was recovered from floodwaters in Gisborne

Three of the other victims were in Hawke's Bay and a volunteer firefighter was killed in a slip in Muriwai.

Police say while the worst of the weather may have passed, Hawke's Bay and Tairāwhiti still face significant and potentially lfie-threatening challenges.

They are focussed on finding missing people and reaching those isolated by floodwaters.

This afternoon, three-thousand-544 people have been registered with police as uncontactable.

Police say many of these are likely to be multiple reports about the same people.

6.30pm: Vodafone's chief technology officer Tony Baird says he appreciates people in Tairāwhiti , in particular, are emotionally distressed at having telecommunications services cut off.

In Hastings, 95 percent of cellphone coverage is back up and in Napier the figure is 30 percent and will improve to 50 percent tonight, Baird says.

The biggest area of concern is the Gisborne area and Wairoa.

He hopes to have five of 15 cell sites restored shortly which will mean about 60 percent of Gisborne residents will be able to phone and text.

"The five sites that will be connected covers the majority of the city area."

People had been helicoptered in with satellite dishes today but once one site was connected through an Optus satellite link it got "hammered" with 1300 connections immediately so it had to be locked down just for police and other emergency services, Baird said.

Two hot spots have been set up at the airport and another one at the police station to enable them to have reliable communications.

In areas like Ruatoria and Tokomaru Bay a fibre-optic cable is used by all mobile companies. It has three breaks in it, and while two can be repaired by tonight, the third will require a more complex repair.

Once it has been done it will take the connection from Whakatāne to East Cape down to Gisborne and is likely to be completed by Friday night.

Power remains the biggest obstacle and cell sites with generators were being transferred to the region and they will be shared by Vodafone, Spark and 2Degrees.

"We're trying to pool resources where we can but it's generators or mains electricity is the main issue."

6pm: Numbers of search and rescue personnel will be boosted by about a third over the next two days, as they try to check every property where people may still be stranded.

USAR team leader Ken Cooper says the 35 newcommers will take his team to about 100-strong and allow them to make a significant push.

Staff are going door to door in priority areas near main waterways, but most rescues are now from tip-offs by the public, Cooper says.

He says the return of patchy communciations has meant people are calling for help, while family members are heading into the Napier Fire Station to alert emergency services.

5.40pm: Residents of a small and isolated settlement near Gisborne say they felt forgotten in the immediate aftermath of Cyclone Gabrielle.

Te Karaka has been hard hit, with almost 600 people evacuating to hilltops at the height of the flooding.

One evacuee, Jasmine Phillips, says it took too long for the government to acknowledge what the community had been through and for supplies to be delivered.

Prime Minister Chris Hipkins visited Te Karaka this morning to see the damage. Phillips says there are many families who are now wondering what's next.

5.35pm: Te Whatu Ora says urgent medical supplies are being flown from Auckland to Tairawhiti and Hawke's Bay. They include medical oxygen, chemotherapy medication, pharmaceuticals, medical nutritional supplies and blood products.

A Defence Force Hercules C-130 is delivering them to Napier and Gisborne.

National Incident Coordinator for Te Whatu Ora, Matt Carey, says the normal supply chain for medical facilities is badly affected and deliveries will continue by air, and possibly by sea, until the roads can be used again.

4.27pm: MetService says severe thunderstorms are moving northeast and expected to be accompanied by torrential rain. A severe thunderstom watch remains in force for Bay of Plenty, Rotorua, Taupō, Gisborne and Hawke's Bay.

The thunderstorms are expected around Rotorua, Waiotapu, Waikite Valley, Waireka and Guthrie at 4.37pm; and near Rotorua, Waiotapu, Waikite Valley, Lake Tarawera, Waireka and Guthrie at 5.07pm.

3.28pm: The HMNZS Manawanui, carrying supplies for cyclone devastated areas on the East Coast, is due to have arrived in Tokomaru in the past hour, and will carry on to Tolaga Bay about 7pm, before travelling to the Gisborne coast tomorrow morning.

Two Light Armoured Vehicles will also check out a road route to Gisborne, so they can look at getting a larger, military reverse osmosis water treatment plant and army staff into the area.

An airforce C-130 Hercules will fly army personnel into Gisborne, along with a second military reverse-osmosis water treatment plant, two Transpower 4WD vehicles and crews from Christchurch to Kerikeri. It has also transported 600kg of civilian communications equipment and 45 oxygen bottles to Gisborne Hospital.

An NH90 Helicopter is helping transport army satellite communications staff into Wairoa and will also be available for moving emergency supplies, such as food, around the region.

3.22pm: Nearly 4500 addresses remain without power across the district, with multiple major faults, Eastland Group says.

Residents in Tairāwhiti and Wairoa may have to wait days before supply is reconnected. Power has been restored to Gisborne City and parts of Wairoa while Ruatorea, Te Araroa, Tokomaru Bay and Tolaga Bay townships, and Mahia, are running on generators.

People are asked to to treat all power lines as live and not to use chainsaws or vehicles to clear trees and roads where power lines are down.

3.20pm: Prime Minister Chris Hipkins has cautioned it may be "some time" before broadband is restored in Gisborne.

Hipkins has been in the region this morning to visit with locals, hear from officials, and see the scale of destruction first-hand. He said officials were focused on improving Starlink connectivity - with phone and text messages likely to come back online first.

The prime minister is now returning to Wellington - and will give a full briefing about 5.30pm.

2.26pm: Tairāwhiti Civil Defence says a short-term solution to bring essential supplies into the region has started today. It says trucks carrying food, water and fuel will travel between Ōpōtiki and Te Karaka on State Highway 2 in a managed convoy.

Civil Defence says there will be two trips a day, one going south from Ōpōtiki in the morning and returning in the afternoon. The road is still closed to the public for the safety of contractors repairing the road between convoys.

1.10pm: Hikuai to Whangamatā is now open for essential travel only between Opoutere Road and SH25A (Hikuai) following a closure for slip clearance this morning.

12.10pm: Ūawa has been hard hit by flooding and forestry slash, with the Hikuwai Bridge on State Highway 35 north washed away. It says Anaura Bay residents are fine, but they have no electricity or no way in or out of the settlement.

12pm: Communications is still severely limited to Ūawa/Tolaga Bay on the East Coast. Civil Defence says it is operating from the school in the town, which it says is okay but cut off. There is a $50 limit for fuel at the town garage, cash only, and the medical centre was open for supplies this morning.

11am: Federated Farmers national board member and local farmer Sandra Faulkner is involved with the rural hub set up as part of the Emergency Management operation in Gisborne. She said every effort was being made to find ways to contact isolated farms and ascertain needs, but one of the challenges was a shortage of AvGas for helicopters.

8.36am: MetService has issued a severe thunderstorm watch for Hawkes Bay from 3pm - 10pm on Thursday. A few of the thunderstorms could be severe about the ranges of Gisborne, and Gisborne north of Tolaga Bay, with localised downpours of 25mm to 40mm per hour and hail.

8.20am: Foodstuffs has been using a helicopter to get supplies into Tokomaru Bay, Tolaga Bay and Ruatoria. The supermarket chain is hoping to get road access to Tairāwhiti on Thursday morning in a guided convoy, its chief executive says.

6.30am Another person has died in the cyclone. Police announced a person had died in Gisborne. They say the person is believed to have been caught in flood waters. Four other deaths were already reported, three in Hawke's Bay and one in Muriwai, Auckland.

6.25am Prime Minister Chris Hipkins is due to fly to Gisborne this morning in what will be his first in-person look at the scale of destruction from the cyclone.

6.20am HMNZS Manawanui set sail for Tairāwhiti at 5pm on Wednesday and was due to arrive at first light Thursday, loaded with water supplies.

Auckland / Northland

6pm: Numbers of search and rescue personnel will be boosted by about a third over the next two days, as they try to check every property where people may still be stranded.

USAR team leader Ken Cooper says the 35 newcommers will take his team to about 100-strong and allow them to make a significant push.

Staff are going door to door in priority areas near main waterways, but most rescues are now from tip-offs by the public, Cooper says.

He says the return of patchy communciations has meant people are calling for help, while family members are heading into the Napier Fire Station to alert emergency services.

4.05pm: Rubber neckers are being warned to stay away from Auckland's Piha Beach as it's still not safe. The West Coast beach is accessible again by a long, alternative route after being cut off by Cyclone Gabrielle.

RNZ reporter Rowan Quinn said locals told her they were appalled to see people from the city cruising out to take a look at their misery.

There are some huge slips in the settlement, and all the houses on the South Piha waterfront are red-stickered. Cellphone coverage has returned but there is still no power.

3.56pm: Auckland's civil defence group is warning people not to take the clean-up of slips into their own hands, saying people want to help but there is a risk of further land instability and geotechnical assessments are needed before clean-up efforts by the professionals can begin.

3.50pm: Waka Kotahi / NZTA is warning people to expect closures across much of Auckland's motorway netowrk tonight including SH1 between Silverdale and Puhoi, and SH20 southbound between Waterview and Hillsborough.

2.42pm: SH1 remains closed between Brynderwyn and Waipu and between Kitchen Road and Makene Road through the Mangamuka Gorge until further notice. Subsidence has also been reported between Kawakawa and Whangārei.

2.21pm: Auckland Council says it is appalling individuals are impersonating council officers to enter people's homes. Council officers will be in a council shirt and have council identification, and should not need to enter properties.

People should ask to see identification before letting anyone inside their homes and anyone concerned about a fraudulent visit should contact police.

2.20pm: Auckland Council says roads blocked by fallen trees and slips continue to be a key challenge to restoring power in the region. Today, Vector is reporting around 16,000 properties without power, and Counties Energy approximately 990 properties.

2.08pm: Civil Defence in Auckland says the priorities today include getting supplies into devastated western parts of the region, but there are lots of risks - slips and damaged roads.

1.08pm: Auckland Emergency Management duty controller Rachel Kelleher says land around the western beach communities remains unstable and people should have a plan to leave quickly, especially if there are slips.

She says the focus today remains on communities that have been isolated by the landslips and flooding, in particular Piha, Karekare, Te Henga (Bethells Beach) and Muriwai.

Yesterday afternoon, 12 tonnes of supplies were delivered by air and ground into some of these areas, she said. Today, they are working to get essential supplies to families isolated at Kaipara Flats and Bethells and properties in other parts of Auckland. They are taking additional water to Muriwai and are hoping to do the same for Piha.

12.45pm: Auckland Emergency Management is urgently asking Helensville and Parakai residents to "please reduce your water use urgently, any way you can, as your local water treatment plant continues to be severely impacted by the affects of the cyclone".

10.55am: Damage assessments are getting underway in the swamped Kaipara town of Dargaville, where some residents spent a third night in evacuation centres. The call was made Wednesday evening for people who live near the Wairoa River, in the centre of town, to evacuate again.

The head of Rūnanga o Ngāti Whātua, Antony Thompson, says a large swathe of town was flooded yet again, though it wasn't as bad as previous night's. Some in remote areas were predicted to remain without power for a week or two.

"In our remote areas - Pouto Peninsula, for example, and Tinopai that are very remote - no power, no communications, no cellphone coverage. We're going out to have a look at those homes when it's safe to do so."

"We're starting to work with some marae to step up generators and mobile shower units so people can go to marae, do what they need to do, and then go back home again."

5.42pm Wednesday: Auckland Emergency Management contracted a private helicopter to help deliver supplies to the region's coastal communities cut off by road. It delivered food and welfare supplies to the Karekare community. Response teams were dropped into the area to undertake welfare checks.

National Emergency Management Agency advice:

  • Put safety first. Don't take any chances. Act quickly if you see rising water. Floods and flash floods can happen quickly. If you see rising water do not wait for official warnings. Head for higher ground and stay away from floodwater.
  • Do not try to walk, play, swim, or drive in floodwater: even water just 15 centimetres deep can sweep you off your feet, and half a metre of water will carry away most vehicles.
  • If you have evacuated, please stay where you are until you are given the all-clear to go home.
  • If you don't need to evacuate, support those who do by staying home, staying off roads and staying safe.
  • If you are not able to contact your whānau in the heavily affected areas go to Police 105 website and complete the inquiry form or phone 105 and remember to update if you reconnect through other means.
  • Throw away food and drinking water that has come into contact with floodwater as it is often contaminated and can make you sick.
  • If you are without power eat the food from your fridge first, then your freezer. Then eat the food in the cupboard or your emergency kit.
  • People should stay up to date with the forecasts from MetService and continue to follow the advice of civil defence and emergency services.
  • A National State of Emergency is in place for an initial period of seven days and applies to regions that have declared a local State of Emergency.
