A climatologist says more of the wild weather that has pounded parts of the North Island this week can be expected in future.
The Greater Wellington Regional Council said that, in some areas, the amount of rain that fell was the most they had had in fifty years.
Victoria University professor James Renwick said climate change meant such extreme weather would occur more often.
He said it was too soon to tell if the rainstorms were caused by the weather pattern El Nino.
Metservice said the greater Wellington region and parts of the North Island's east coast can expect a few showers this evening and tomorrow morning.
