Brief isolated showers were possible in the Waikato and perhaps central North Island this afternoon.
"About the lower North Island, west to northwest winds will prevail in the west, with a mixture of sunny areas and some cloud," weatherwatch.co.nz said.
The east coast of Northland and Bay of Plenty would probably experience sea breezes this afternoon.
Wellington would be mostly sunny today with northerly winds and a high of about 21C.
WeatherWatch said Nelson and the South Island east coast should be sunny but a few light showers were possible in Otago this evening.
MetService said a ridge of high pressure would cover the country tomorrow, but weaken over the South Island on Sunday ahead of an oncoming front. Patches of rain or showers were expected over the South Island as the front moved northward, MetService said. "There is a low risk of heavy rain about Fiordland on Monday, with a moderate risk of severe northwest gales about Southland and Clutha, including Foveaux Strait, during late Sunday and early Monday."
Northland had a sunny day yesterday but a few afternoon showers were possible there tomorrow. Auckland would be partly cloudy and mild for the next few days, with extended sunny spells.
Year off to hot start with perfect conditions for the races - and there's more to come
