Thousands of Aucklanders still without power after the storm that battered the region face the prospect of a chilly night.
Several hundred outages are continuing to affect around 93,000 homes and businesses in the region, Auckland Civil Defence and Emergency Management says.
With temperatures expected to drop to around 6C overnight, director John Dragicevich is urging people to check on neighbours, friends and family.
"Some people have been without power for almost 24 hours - this means cold water, food hygiene issues and a chilly night without heating," he said.
"If you live next to someone who may be vulnerable, please pop over and check on them."
Around 90,000 homes have head their power restored since the worst of the storm, which struck on Tuesday night and Wednesday morning.
Those without electricity have been told it could be several days before the supply is reconnected in some areas.
The storm brought winds that gusted to 213km/h, leading to questions about whether forecasters and authorities were caught unprepared.
But Mr Dragicevich defended the response.
"As soon as we received advice from MetService yesterday, we advised our stakeholders and provided advice to the public via social media," he said.
"This was updated throughout the night and this morning."
He also said MetService's advice - after a tornado and high winds sweep through Taranaki - that the storm system was moving north, was extensively covered by media.
"We must remember that there will always be some uncertainty with weather events and their impact," he said.
"But Auckland Emergency Management, and the region's emergency responders and power providers, planned and acted appropriately."
Mr Dragicevich said his organisation, like other agencies, relied on forecasters for weather advice and "MetService's prediction on this event was accurate".
Another burst of heavy rain and wind is forecast to cross Auckland from 9pm on Thursday, and a severe weather watch is in place for the region and Great Barrier Island.
