MetService predicted cool but sunny weather as the country headed to the polls on Saturday.
Spokesperson Bob McDavitt said there would be no extreme wind or heavy rain to keep people away from the polling booths.
He said there would be a frosty dawn over much of the South Island and parts of the central North Island, followed by a sunny day.
Mr McDavitt said some centres would not shake the chilly condtions entirely, with Wellington, Christchurch and Dunedin reaching just 12 degrees.
The Far North was likely to experience the country's warmest temperature of 19 degrees, but with a few showers in the afternoon.
Mr McDavitt says conditions should otherwise remain stable across the country.
The settled weather is not predicted to last - wind and rain are forecast from Monday.
