Auckland and the central North Island have shivered through another freezing night, but parts of the South Island had some respite under a blanket of cloud.
The coldest spots at 5.30am were Taupō Airport at -2C and Waiouru on -1C.
Auckland warmed up slightly from yesterday, which was one of the coldest days in the city in the past three years.
This morning Ardmore was down to 2C and Auckland Airport was at 4C.
Yesterday Ardmore dropped to -0.9C and the rest of the region sat around a chilly 2-4C.
So, has it been a colder than average start to winter?

MetService lead meteorologist Mark Todd said the coldest areas this morning were in the central North Island high country, but a layer of cloud kept temperatures higher than expected in the South Island.
"Christchurch, which you would expect to be fairly chilly, is sitting at 7C, so not too bad.
"That cloud is acting as a good insulator."
Scattered rain was forecast in Southland and Clutha today, and isolated showers for coastal areas from Northland down the North Island's west coast, and on the east coast from Wairarapa to south of Mahia.

Apart from those areas it was shaping up for a fine day, Todd said.
"Things should continue to improve through the day, as a high pressure system continues to slowly build over the country."
Tomorrow and Saturday were looking like much of the same, as the ridge of high pressure moved east over the country, bringing a period of settled weather.
However, frosts were likely with the clear conditions, and icy conditions could affect some inland roads.
"It is looking to be calm and clear the next few days so will continue to be chilly overnight," Todd said.
A front was expected to move east over the country on Sunday, bringing a period of rain to many places, especially in the west - falling as snow about the mountains.
The front cleared the North Island on Monday, and a broad trough moved slowly northeast over the South Island.
