Storm-battered Aucklanders are in for a chilly night with overnight lows of six to seven degrees expected and Civil Defence is urging people to check in on the vulnerable.
Several hundred power outages are affecting 93,000 homes and businesses, though around 90,000 homes have had their power restored since the worst of the storm last night.
Some people have been without power for almost 24 hours, meaning cold water, food hygiene issues and a chilly night without heating, said Civil Defence director John Dragicevich.
"If you live next to someone who may be vulnerable, please pop over and check on them," he said tonight.
People who can't call on family or friends for help can call Auckland Emergency Management on 0800 22 22 00 for advice and assistance, If your life is at risk phone 111.

Another burst of heavy, possibly thundery rain and wind is forecast to cross Auckland from 9pm tomorrow and a severe weather watch is now in place for the Auckland region and Great Barrier Island.

The expected gusts with the second event are likely to be at lower intensity than seen last night.
