Weather: 'Big-time changes' on the way, cold weather to follow warm weekend

Forecasters are warning the weekend's predicted warm weather won't last, as a "polar blast" makes its way to the country.

Saturday and Sunday are expected to be warm and sunny with NIWA Weather predicting highs of 15C for Wellington and Christchurch.

Auckland's going to be even warmer, with a predicted high of 16C.

But NIWA Meteorologist Chris Brandolino told The AM Show there are changes on the horizon.

"Next week big-time changes are coming, big time," he said.

"Tuesday could be a quite active day weatherwise across the country and then it's after that we see a real polar blast coming Friday."

Brandolino said Kiwis should make the most of the good weather before it changes next week, sentiments echoed by forecaster MetService, who said the "world's strongest" high-pressure system is headed our way.

It said next week's bad weather is expected to be short-lived and will give way to more summery temperatures towards the end of the month.
