It's set to be a very hot, dry end to November with some areas due for no rain at all before December 1.
Some regions will see highs 10C above average, particularly inland and eastern areas, forecaster Weatherwatch says.
Tonight and tomorrow morning could still be a little cool before the temperature soars, with this weekend and next week likely to see highs in the late 20Cs or possibly 30C in some regions.
The entire North Island will be dry for the next seven days as will much of the South Island, Weatherwatch said, thanks to a high pressure system.
Southland, Otago and Taranaki could see a shower or two while the West Coast would have some rainy days.

Head forecaster Philip Duncan said there were parts of the country that would receive 0mm for the remainder of the month.
"Places like Nelson, Marlborough and Northland may receive no rain at all, not even a shower, for the rest of the month. Other regions like Waikato, Auckland, and Wairarapa may get 0.2 to 1mm".
Remote inland areas in both islands would be verging on heatwave criteria, with at least four days coming where the temperature was 5C+ above normal, the forecaster said. Five days in a row is the technical definition of a heatwave.
It's a far cry from the thunderstorms, lightning and hail that smashed parts of the South Island yesterday.
Golfball-sized hail chunks reportedly broke windows and damaged roofs around midday on Wednesday, while on Monday a tornado ripped through Christchurch CBD, injuring two people.
