The warm weather is expected to continue over the next week - and it’s only going to get hotter.
Speaking to The AM Show, NIWA forecaster Chris Brandolino says the South Island has been facing temperatures in the upper 20s and low 30s.
We're gonna see more of that pretty much the entire week.
Mr Brandolino also emphasised the need for people to get sun-smart.
He says the sun reaches its maximum intensity between 10am and 4pm but you can get sunburnt regardless of cloud cover.
"You don't associate overcast with getting sunburnt, but the sun's that powerful."
