Tauranga has reported its fourth hottest January temperature since records began there in 1941.
On Monday, the Bay of Plenty town recorded the country's hottest temperature at 31.9°C.
Meanwhile, a large cyclone and eruption-driven swells have started to ease along the Mount Maunganui and Pāpāmoa coasts but beachgoers are still being advised to avoid the water.
Surf Life Saving NZ search and rescue manager Allan Mundy said the water was still too hazardous for swimming.
