Strong winds are expected to hit the North Island.
MetService has issued a severe weather watch for Sunday, with gale force winds up to 85km/h to hit most of the North Island.
Winds are expected to affect Taranaki out to the Coromandel, and Auckland, with MetService meteorologist Andy Best saying he "doesn't expect it to be nice anywhere in the North Island" on Sunday.
Periods of heavy rain and thunderstorms are expected as well.
WeatherWatch said a developing low, which is connected to a system in the Southern Ocean, will move off the South Island's West Coast on Sunday and into the North Island.
