Kiwis are set to bask in toasty weather over the next few days before heavy rain hits on Mother's Day.
Warm winds blowing in from the sub-tropics or Australia means almost all New Zealand is expected to enjoy warmer than average temperatures today and tomorrow, WeatherWatch said.
It's led almost the entire South Island to enjoy temperatures 4C to 8C above average, despite rain already hitting parts of the West Coast.
But tomorrow will be even warmer.
Christchurch and Dunedin can expect highs of 20C and 19C as temperatures in all South Island regions will be at least 4C above average, WeatherWatch said.
Auckland, large parts of the Waikato, Taranaki and the East Coast will also soar between 4C and 8C above average tomorrow.
It means Auckland residents can expect highs of 21C tomorrow and Saturday with Napier even tipped to hit a high of 24C, something WeatherWatch described as "exceptionally warm for the second week of May".
However, rain is expected to also make its way up the country as a "complex trough" arrives from the Tasman Sea and spreads across most of the country on Sunday.
The heaviest falls would be in western and central areas, but the upper North Island including Auckland would also see some rain on Sunday.
This front could also bring northerly gales, becoming severe from Auckland to Whanganui, and also Wellington, northern Marlborough and Nelson.
On Monday, a strong and showery southwest flow over New Zealand would ease, as a ridge developed - bringing more settled weather.
