However, people in the west of the South Island should prepare for some wet weather.
MetService issued a heavy rain warning for Westland north of Harihari which is only expected to lift at 4am on Tuesday. While a heavy rain warning in Buller south of Karamea is only expected to lift at 6am on Tuesday.
"We have got a cold front travelling up the South Island, so we've got some quite heavy rain associated with that in the west of the South Island," Bellan said.
As regions across the country record warm temperatures, Bellan said a few temperature records have been broken, with Kawarua reaching 30C just a few days ago.
"We have seen 30 breached in a few places, so just with these northwesterly flows we can get these conditions."
Meanwhile, the Capital has recorded temperatures in the low twenties which Bellan said is expected for this time of year.
Moving down to the South Island, Bellan said cooler temperatures are expected today.
"We're looking at places back in the mid-teens even with the likes of Oamaru, Timaru and down further south in Gore because it's a bit cooler than normal for them in the next few days."
Looking further into the week, warm and sunny weather is forecast as New Zealanders prepare to see in the New Year.
With more hot weather on the cards, Bellan is asking New Zealanders to remain sun smart when enjoying the sun.
