Sunday is shaping up to be a scorcher for parts of New Zealand with the mercury tipped to reach a sweltering 28C in the hottest region today.
Forecaster Niwa says a warm air mass off Australia has taken a roundabout route from the neighbouring continent seeing temperatures soar as high as 27-28C in North Canterbury in the coming hours.
The summer-like conditions were expected to bring well-above average temperatures to east of the South Island, with much of the country also set to enjoy blue skies and warm conditions.
While holiday hotspots in the north are expected to enjoy temperatures around 20C, Christchurch is expected to be a balmy 24C by early afternoon.
After midday Hanmer Springs in North Canterbury had recorded the country's first 25C temperature reading for spring.
