Emergency services are busy in Wellington tonight as the city is battered with heavy rain, with some areas flooding.
MetService has issued a severe weather warning for the Wairarapa, Wellington, Fiordland, Otago, Westland, Nelson and Taranaki.
Heavy rain is expected to fall on the Tararua Ranges, easing overnight, but streams and rivers may rise rapidly, MetService warns.
Wellington Police and Fire Communications' fire shift manager said they have been busy with "lots of minor flooding incidents" around Titahi Bay and Porirua.
Resouces weren't exactly strecthed, he said, but many crews were out dealing with flooding in streets and houses.
There were also some powerlines arcing and a roof caving in in Pukerua Bay, and flooding on State Highway 1 at Paekakariki has closed part of the road.
The weather seemed to be moving further up the coast, with incidents also being reported in NaeNae and Waikenae, he said.
This is the first significant burst of rain for some time, with the dry spell causing severe water shortages and fuelling large scrub fires around the country.
But the extreme weather is not expected to last long, and it may not be enough to reverse dry conditions.
MetService says a new high will build over the South Island tomorrow, extending over western parts of the North Island in time for Waitangi Day on Wednesday, bringing a return to dry and settled conditions.
Regions from Gisborne to Wairarapa should see lingering showers for much of Waitangi Day, with cloudy spells along east coasts of both islands, MetService predicts.
