Aucklanders were in for a high of 20C and a low of 12C overnight.
Tauranga and Hamilton were in for a very similar looking day, with temperatures peaking around 19C.
Things were not so peachy on the east coast of the North Island - temperatures were lower at 15C and there was a chance of a shower in the afternoon.
Glassey said would likely be a bit of cloud along this coast - from Gisborne down to the Wairarapa.
"They've got some cloud, there's also a few showers around Northern Hawke's Bay into Gisborne," he said.
"Tomorrow, there is another weak front that is moving onto the South Island."
The bottom of the South Island could expect a few showers over Sunday afternoon, these would then move inland and further north later in the day.
Some of this wetter weather would spread up to the North Island by Sunday afternoon - with the worst of the showers likely to hit spots on the East Coast like Gisborne.
