The big cleanup has begun after a flash flood ripped through West Auckland.
A heavy downpour battered Auckland on Sunday, dropping 65mm of rain on the west of the city in just one hour at about midday, causing flash-flooding and inundating more than 320 homes throughout the city, some of them waist-deep.
However, the Fire Service said the situation was now under control and the water was subsiding.
Auckland Civil Defence said for people to call 0800 22 22 00 if their homes were damaged and they were unable to stay with friends.
Multiple people had been trapped in floodwaters on Great North Road in New Lynn and there were also reports of people trapped in shops in the suburb, the service said.
Crews used ropes to rescue those trapped, saying they were suffering from exposure.
The Fire Service received nearly 600 emergency calls since 6am, averaging a call every 24 seconds.

A Bunnings Warehouse in New Lynn had to be evacuated and was then closed because of flooding.
Rotorua stream has broken its banks
About half a dozen houses were threatened by flood waters after the Utuhina Stream in Rotorua broke its banks.
The stream runs through the city and it is running high after the rain over the weekend.
