Workers have been out since dawn trying to clear SH6 on the West Coast so it can re-open to traffic.
MetService lifts heavy rain watches across much of the country but substantial amounts of rain still fell over the West Coast of the South Island overnight.
Road crews have been out since dawn and have made good progress working to reopen State Highway 6 between Ross and Haast.
The section of state highway was closed yesterday afternoon after heavy rain brought down trees and slips along the route, including a large slip at Lake Ianthe between Ross and Harihari.
A Waka Kotahi spokesperson said sections of the state highway between Haast Pass and Franz Josef, and Ross and Whataroa reopened about midday.
However, it was closed between Whataroa and Franz Josef due to flooding and multiple slips.
Travellers were being encouraged to consult Waka Kotahi's Journey Planner.
The spokesperson said the bad weather has left its mark on the highway with lane and speed restrictions in some places, particularly at the larger slip site near Lake Ianthe.
Further inspections to SH6 will be carried out after river levels along the lower West Coast recede.
MetService duty meteorologist Clare O'Connor said 70mm of rain fell on Haast and some areas in the inland ranges of Westland saw in excess of 200mm.
She said conditions in northern parts of the country had eased, but some isolated showers were still possible today.
O'Connor said the country could expect more settled weather in the week ahead.
MetService has warned a cyclone forming near the Coral Sea off Queensland could affect the north.
Meteorologist Jessie Owen said a front that moved up the country on Sunday would clear the North Island tonight - taking with it humid air that had brought heavy rain.
However, a tropical low, expected to develop into a cyclone over the next couple of days, could track towards the Far North of New Zealand next weekend.
The cyclone may bring strong winds, heavy rain, and large swells on eastern coasts if it passes close to the North Island.
Coromandel travel updates
Coromandel mayor Len Salt said holidaymakers have options heading home today, as more of the region's roads are back open.
State highway 25A remains closed between Kopu and Hikuai, as does the gravel road between Tapu and Coroglen.
However, he was happy that travellers can now choose between travelling home north through Coromandel town, or south through Whangamata.
Salt said people still needed to drive carefully as there may be remaining dirt or debris on the sections of the road that were cleared.
Appeal for help for flood-hit Auckland pupils
KidsCan said Auckland schools affected by the flood were in desperate need of food, clothing and shoes.
The charity has been strengthening the help provided to more than 250 schools and early childhood centres in Auckland, and assessing what affected families need the most.
Chief executive Julie Chapman said many families lost everything.
The charity was providing extra food to schools operating as emergency hubs, and working on long-term support for families affected, she said.
The SPCA has appealed to pet owners affected by the flood to contact council shelters for help if they needed to temporarily find a home for their animals.
The charity has had to close several centres in Auckland due to flood damage.
SPCA chief executive Gabby Clezy said although centres were likely to remain closed for a while, the charity was providing care packages, including food, medication and bedding for animals.
She said donations of blankets, towels and flat sheets were needed.
Teams from across the motu are working to contact people in hard-to-reach areas hit by last week's massive floods in the Auckland region.
Auckland Emergency Management said Red Cross workers from Invercargill, Christchurch, Wellington and Kāpiti as well as response teams from Palmerston North, Tauranga and the capital have converged on the region.
The council's building consents team has red stickered over 270 buildings after completing nearly 5000 rapid building assessments in the last week.
On the roads, Auckland Transport said it hoped to reopen the westbound lane of Tamaki Drive in the next 24 hours.
Flood response inquiry just a starting point - councillor
Auckland councillor Daniel Newman has welcomed a review into the council's flooding response, but said a more in-depth one will be needed in the future.
Mayor Wayne Brown's office at the weekend announced a review into the immediate response to the flooding, to be led by former police commissioner Mike Bush.
Newman hoped the review would bring transparency and information about what could be done to immediately effect change, but said more work will be needed.
The initial budget for the review is $100,000, with the aim of it being completed in one month.
