A cold front could cause temperatures to plunge later this week, particularly in the South Island.
NIWA meteorologist Chester Lampkin said for the past couple of days there has been high pressure across New Zealand, but that is set to change.
A moisture-laden tropical low is nearing New Zealand, which will lead to a cold southerly change, particularly in the South Island, he said.
Towards the weekend, there could be the possibility of a tropical cyclone or low reaching the North Island, he said.
A stunning day is forecast on Wednesday for most of the North Island and the top of the South Island with temperatures reaching the mid to late 20s, he said.
But a southerly front reaches the lower South Island later on Wednesday, he said.
“And then late in the day a shower and even a few thunderstorms for Fiordland and parts of Southland and Stewart Island,” he said.
A west south-west change will lead to showers and even thunderstorms across parts of the South Island on Thursday, he said.
By Friday temperatures will be 3C to 5C below what is considered average in the South Island, he said.
