For the North Island, Makgabutlane said temperatures are decreasing from Thursday into Friday, “mainly into central parts of the island and eastern parts, and then into lower parts of the island too”.
Taupo can expect a high of 13C on Thursday, along with Taumaranui. Meanwhile, further south, Wellington can also expect a high of 13C.
In eastern parts of the island, Masterton will drop to a high of 14C on Thursday.
“The coldest morning of the week will be Saturday, where parts of the central North Island, specifically Taumaranui, will plummet to 2C,” she said.
“On Saturday morning there will be possible frost outside, and for those in Auckland it will feel pretty chilly waking up to 9C to start the day.”
In the South Island, Kiwis are warned to expect those snappy temperatures earlier, from as soon as Wednesday.
“Parts of the Southland and Gore will see a high of 10C on Wednesday, while Invercargill and Dunedin will reach 11C max.”
Makgabutlane said Queenstown’s high will be 12C on Wednesday.
“It will be quite cold down there,” she added. However, she said there “won’t be any significant snow in the South Island”.
And she has some advice for those wanting to be prepared.
“Keep an eye on the forecast, make sure to have your winter blankets out, and don’t underestimate those colder temperatures before heading out the door,” she said.
“It’s that time of year where those winter blankets are definitely needed.”
