Kiwis might be nursing their first sunburn of the season after a sunny weekend graced most of the country.
On Saturday northern and eastern parts got up to 24C. But it would have felt even warmer for those basking in the sun, Met Service meteorologist Sarah Haddon said.
"Gisborne got up to 24C and Northland 23.5C, Hawkes Bay was 22.5C and Auckland got to 18C.
"The temperatures are taken in the shade, if you were standing in the sun at any point it would feel a lot warmer because the sun is directly on you."
A front crossed over the South Island on Saturday bringing showers to the west coast. Haddon said some areas would have accumulated up to 50mm over the whole weekend.
Temperatures plummeted at night as clear skies followed the front, Ranfurly dipped below 0C overnight on Saturday. Waiouru and Milford Sound didn't even get into double digits on Sunday with a high of just 9C.
The front petered out around the Cook Strait on Sunday so only scattered showers and wind made it up over the North Island. Gisborne was the warmest being the only place to top 20C.
This week will see settled and sunny weather for most parts of the country, although in classic spring fashion most places would get showers and eastern parts of the North Island would get more cloud than they're used to, Haddon said.
"There's not one dominating feature over New Zealand this week. Some days there will be showers, some days will be fining up.
"We're moving towards summer so overall things will start getting warmer, but there's no way I can say the cold is completely gone. There could be another southerly kick."
