After a frosty start most of the country should clear for a fine and sunny winter's day.
MetService lead forecaster Michael Martens said clear skies in many places overnight let the heat out, and dropped temperatures well into the negatives.
The coldest temperature overnight was -5C down at Pukaki in the central South Island.
St Arnaud in the Nelson Lakes region dropped to -4C while the coldest North Island temperature was -2C at Tongariro.
"As the sun comes up it should be a mostly fine day across the country, with only a few showers remaining in western areas," Martens said.
Another front expected to bring showers to the west and southern areas of the South Island tomorrow. With snow expected to lower to 300m in Southland and Otago for a time. A high pressure to the north keeps the weather mostly settled for the North Island. ^KL pic.twitter.com/0pXQTyl521

The next front would arrive this afternoon in the South Island, bringing a period of rain to Southland, Otago and Fiordland, spreading into Westland and Canterbury by the evening.
"It will be quite a vigorous front, with strong winds and potentially squally thunderstorms.
"A burst of cold wind behind it will bring a southwest change, with snow lowering to 400m in the South Island."
Road snow warnings were already in place overnight and this morning in the South Island for Arthur's Pass (SH73), Porters Pass (SH73), Lindis Pass (SH8), Crown Range Rd and Milford Rd (SH94).

Here's how the next few weeks are looking:
◘ Turning more settled in the short-term.
◘ Active weather returns Sunday & next week.
◘ Colder but a bit drier to round out July, especially south. pic.twitter.com/JOjb4AihM5
The front would arrive in the lower North Island tomorrow morning bringing showers with it, but it would weaken as it moved further north through the day.
"Generally the weather will gradually clear on Thursday across the country, with only a few showers remaining in the upper North Island from Coromandel to Northland."
Friday was not looking too bad either thanks to a ridge of high pressure across the North Island and east of the South Island.
The West Coast of the South Island would start to feel the effects of another system out in the Tasman Sea on Friday.
"That system will rotate on Saturday closer to New Zealand, spreading rain to most places late Saturday and into Sunday," Martens said.
"So the weekend is not looking too nice, quite changeable with rain."
