A high of 17C and overnight low of 8C is forecast for Auckland. Hamilton and the rest of the Waikato sees similar conditions today and tomorrow.
MetService says a high pressure system over New Zealand is to thank for the settled conditions.
"It will be great weather for weekend sport and gatherings - perhaps a barbecue ahead of watching the All Blacks [tomorrow] night," a spokesman said.
Daylight hours are also starting to increase quickly, day by day.
There might be a light shower or two in Northland tomorrow afternoon - as well as in the east coast in the morning - but otherwise fine, WeatherWatch analyst Aaron Wilkinson said.
People in Kaitaia today can look forward to fine spells and a high of 17C. But there is a chance of a shower and it will be a cold night, with an overnight low of 7C forecast.
Those in Gisborne can expect a few showers this morning and there will also be isolated showers in Wellington later in the day.
Wilkinson said it will be mostly sunny on both islands today.
"The South Island has a mainly sunny day - some cloud in the west, especially about South Westland."
It's all sunshine in Nelson while Christchurch and Invercargill can expect fine conditions, save for cloudy patches.
MAKE THE MOST OF THIS WEEKEND:
Anyone hoping the beautiful weather will continue into next week will be left disappointed.
"The next weather feature is expected to cross the country early next week, bringing rain to both islands as the high moves away.''
On Sunday a front, preceded by gale north to northwest flow, is forecast to approach the lower part of the South Island from the southwest.
"There is low confidence of north to northwest gales becoming severe in exposed parts of southern Fiordland and coastal Southland including Steward Island on Sunday.''
The front is expected to move across the South Island on Monday and then towards the North Island on Tuesday - bringing with it periods of heavy rain.
At the moment, the MetService says there is low confidence of rainfall accumulations reaching "warning amounts'' in areas such as Westland and Fiordland on Monday and about the Tararua Range and Mt Taranaki on Tuesday.
