A briefing for evacuated residents was held on Thursday morning at the Halswell Community Centre.
State of Emergency
A State of Local Emergency was declared for Christchurch City (which includes Banks Peninsula) and Selwyn District on Wednesday.
"The declaration means we are better able to coordinate our response across all the various agencies involved, and will mean we can get assistance to where it's most needed. It also means the local controller can evacuate people or restrict access to affected areas as required," Christchurch mayor Phil Mauger said.
Warnings
Christchurch's mayor Phil Mauger is warning residents not to breach police cordons around the Port Hills fire.
He said people should not enter the cordon without emergency services' approval.
A public health warning for smoke from the fire was issued on Wednesday by Te Whatu Ora.
Medical Officer of Health Matt Reid said exposure to smoke can worsen pre-existing health conditions, including heart and lung disease.
The smoke could also cause coughing, shortness of breath or eye, nose and throat irritation for pregnant, young or elderly people.
People were advised to stay inside, restrict outdoor exercise, switch air-conditioning to recirculate, and keep pets inside.
Anyone feeling anxious could contact Healthline on 0800 611 116.
The Asthma and Respiratory Foundation warned inhaling smoke could worsen conditions like asthma as tiny particles entered the throat and lungs, causing irritation.
Medical director Dr James Fingleton said it could trigger flare ups and lead to people being hospitalised.
"It's imperative for everyone to recognise these risks, understand how to manage them, and actively reduce their exposure," he said.
He advised sufferers going outside to wear a N-95 or KN-95 mask, and keep their reliever inhaler close.
People were being urged to stay away and not fly drones anywhere near the blaze because the helicopters would need to be grounded.
Second blaze in Selwyn District
Firefighters have brought a second fire that was threatening buildings south of Christchurch under control.
The grass fire was reported shortly before 9am near Rolleston in the Selwyn District.
Eight trucks attended and crews were "mopping" up the scene about 11am.
Waka Kotahi said earlier smoke was reducing visibility on State Highway 1, north of Rolleston, between the intersections with Berketts Road and Robinsons Road.
