Icy temperatures in the South Island and lingering showers in the north will clear this morning for a fine winter's day.

MetService meteorologist Michael Martens said there were widespread frosts across Southland, Otago and Canterbury with temperatures between 0C and -3C early this morning.

The coldest spots were Lake Pukaki and Mt Cook Airport, both at -5C.

Ranfurly dropped to -3.7C and Dunedin Airport -3C.

Frosts are likely over most of the South Island and central parts of the North Island on Monday morning. Motorists in these areas should also be aware that black ice is likely on the roads. Check tomorrow's forecasts at https://t.co/hnwmGxCqpj ^SG pic.twitter.com/8fUEkzK2HR

MetService warned motorists in these areas there could be black ice on some roads.

The cold did not quite reach the North Island due to some cloud cover and light winds.

Showers in Northland and Auckland, and up the east coast from Wellington to Gisborne, would clear through the morning for a fine day, Martens said.

"That will be the story across most of the country, with those showers easing in the north and clear skies in the south."

Make the most of it though, as another front would arrive tonight in Fiordland and Westland, spreading rain across the country tomorrow.

"It will be the same story - rain heaviest in western areas, dry in the east.

"This front will bring a few days of unsettled weather, until a weak ridge develops over the South Island on Friday."

While temperatures in the North Island were forecast to drop tonight, bringing frosts to central areas, the north/northwesterly flow over the coming days would bring warm air across the country.
