New Zealand authorities say the severe storms that hit western Auckland yesterday left a damage bill costing about $9 million.
Winds gusting up to 140 kilometres an hour struck Hobsonville, killing three construction workers and injuring seven people, several of whom remain in hospital.
Hundreds of houses are still without power.
Building assessors have begun examining the 150 damaged homes to determine if and when residents can return.
250 people had to find alternative accommodation overnight.
