Kiwis should plan to get the sunglasses out and keep the sunblock handy as most places are in for a period of fine and sunny weather.
It comes as a ridge of high pressure remains slow moving over New Zealand bringing minimal risk of severe weather, according to MetService.
With that high pressure being slow moving, Kiwis can expect a few days of fine, sunny weather.
"It's going to be mainly fine weather for the majority of places. There will be the odd bit of cloud about and the deep south will see a little more cloud than most with just the way the winds are going, bringing some onshore clouds," MetService meteorologist Dom Barry told Newshub on Sunday morning.
"Moving into tomorrow [Monday], that ridge slowly tracks to the east, however, it's looking like it's going to be mainly fine for most again still."
The good weather is set to continue on Tuesday but Barry warns there could be some cloud around for parts of the South Island.
"As we move into Tuesday, things do start to get a little bit cloudier in the south as the ridge moves off and winds start to pick up for the likes of Fiordland, Milford, that kind of area otherwise, mainly fine for most, I would say," he said.
Not only will Kiwis get a spell of fine weather the temperatures are also going to be warm – making it good beach weather.
Barry said most places around the country should see temperatures in the mid-twenties over the coming days but some areas will see the thermostat soar.
Barry told Newshub Alexandra is the place to be on Monday with an expected high temperature of 31 degrees.
In the North Island, Dannevirke is the place to be on Monday with an expected high of 26C.
But Barry did warn a front is looking like coming over New Zealand towards the middle of next week, which could bring rain to some places.
"Heading into the middle of next week, we do have a front that appears to approach the South Island at this stage and move up it," he said.
"However then another ridge appears behind it later on next week. So a ridge and then a front to break it up and then we've got another ridge coming on."
But he told Newshub with that ridge of high pressure on the horizon, Kiwis can expect more fine weather to come at the end of next week.
"When the front comes up, we can expect there to be a little bit precipitation with that but aside from that, it's looking like summer has finally arrived for those places that have not quite experienced it yet," Barry told Newshub.
