From Northland to Manawatu, including Coromandel, Bay of Plenty and the central high country, it is expected to be mainly fine despite areas of cloud this evening and tomorrow morning (Saturday).
Horowhenua, Kapiti Coast, Wellington and Wairarapa have had cloudy periods today with drizzle about the Tararua Range but this too is tipped to clear up by tomorrow morning.
The North Island will have mostly fine weather, with highs in the mid- to late-20s for some spots.
"The Bay of Plenty and some inland areas of the Waikato could hit 27 degrees over the weekend and Hawkes Bay and Gisborne could reach the early 30s," Wilkinson said.
For Aucklanders, Anniversary Day on Monday is expected to be fine with light winds, but no rain.
That's good news for the many events on in the city this weekend, including the Laneway Festival and the Buskers Festival in the CBD, Chinese New Year celebrations, and the Black Caps v Australia in the cricket at Eden Park on Monday.
"Saturday should be good for most areas, with Fiordland the only place that's likely to get rain," MetService meteorologist Kyle Lee said.
"Sunday should be pretty good too. Most of the North Island will be good, with just the Tararua Ranges and eastern Bay of Plenty expected to get some rain."
Another front is expected over the South Island, bringing showers to Southland, Westland and Nelson/Buller on Sunday. Canterbury should escape the rain, but it will be overcast.
Monday should be mostly warm and dry, though the Wellington and Wairarapa regions could get rain early in the day. The east coast of the North Island could also get a couple of afternoon or evening showers.
