Taranaki and Tasman, followed by the West Coast of the South Island, have been hardest hit by ex-cyclone Gita.
Fire and Emergency received more than 400 weather-related calls yesterday between 2pm and midnight.
Communications advisor Joss Debreceny says there were another 25 calls between midnight and 4.30am.
They are expecting more calls as day breaks and people wake-up to discover damage.
Debreceny says the calls were clustered around Taranaki and Tasman yesterday but have been more spread out in the last few hours.
He says crews have been helping with clean-up around the country and resolving calls received yesterday.
