Although wintry temperatures will continue this weekend, it won't be as cold as Thursday night.
This morning, parts of the country woke up to sub-zero temperatures amid fears there would not be enough electricity.
The coldest center on Friday was Christchurch at -6 degrees Celsius, MetService said.
MetService meteorologist John Law said more cloud would move towards Canterbury overnight, as well as Hawke's Bay and Gisborne on the North Island, but it would not be as cold as Thursday evening.
Waikato, Bay of Plenty and the central North Island would be cold and icy again on Saturday morning, Law said.
It would be around 2 to 3 degrees Celsius in Hokitiia and Greymouth, and it would also be icy in southern parts of Canterbury.
“We're heading towards the end of the day by now [Saturday] The skies will become clearer again and if we see showers around these eastern areas or perhaps in the far south, it won't be that much – it's just a bit more cloud.
“In places like Northland and Auckland it will remain quite dry and quite clear during the day.”
Temperatures in central areas would drop back to below freezing on Saturday night, Law said, while Palmerston North would drop to around 2 degrees Celsius.
“More cloud towards Whanganui, towards Manawatū and Wellington, and I think as we get through the morning that should start to break up and clear.”
It was expected to be a nice, clear night, but quite chilly heading into Sunday morning, he said.
Auckland's North Island will reach highs of 15 degrees Celsius on Sunday, with Tauranga looking to be the spot with plenty of sunshine reaching 16 degrees.
The South Island looks fine and dry during the day on Sunday, but there will be more cloud for southern parts of Otago and the odd shower for Southland and the Fiordland coast, Law said.
“But for most of us it's a dry story.”
