Rain is edging on to the country today as a front arrives from the Tasman Sea.
The heaviest falls will be over the west coast of the South Island, before reaching the lower North Island this evening and Taranaki tonight, MetService meteorologist Philippa Murdoch said.
The upper North Island and eastern areas would be sheltered though and are in for a mostly fine day.
Auckland was in for a partly cloudy day, with the chance of a shower with northeasterlies and a high of 21C.
The front would cross the North Island on Friday bringing showers and some rain in western areas. Meanwhile the South Island would see a few leftover showers in the north and west.
Heading into the weekend a "complex trough" was approaching from the Tasman Sea, bringing another round of heavy rain to the South Island's west coast on Saturday, before spreading across most of the country Sunday.
The heaviest falls would be in western and central areas, but the upper North Island including Auckland would also see some rain on Sunday.
This front could also bring northerly gales becoming severe from Auckland to Whanganui, and also Wellington, northern Marlborough and Nelson.
As the low moved east of the South Island on Sunday, a period of southerly gales was possible about the east coast from Otago to Marlborough.
On Monday, a strong and showery southwest flow over New Zealand would ease, as a ridge developed bringing more settled weather.
