The mercury has climbed in eastern parts of New Zealand to 24C as a warm air mass takes hold.
After a warm 19C start at 9am, the temperature rose to 24.2C in Napier at 1pm. Gisborne was a warm 23.5C and Hastings an enviable 22.8C at 1pm.
Metservice meteorologist Cameron Coutts said there were still a few hours of heating left in the day from a strong westerly wind that could result in higher temperatures.
The early afternoon temperature in Auckland was hovering between 18C and 19C.
Further south, it was 14C in Wellington and a chilly 10C in Milford, and 11C at Franz Joseph and Haast.
Dunedin and Invercargill were 12C at lunchtime, but a puff of a northwesterly had brought a warm 19C to Christchurch, Coutts said.

Warm air from across the Tasman has moved on to eastern regions and is bringing an early taste of summer to parts of the country.
The warm spell is expected to last two days.
Niwa said the early-morning temperatures across the East Coast were more in tune with the average top temperature of an October afternoon.
