With spring upon us, NIWA has released new data showing New Zealand experienced its warmest and wettest winter on record with a meteorologist describing it as "mother nature's way of expressing she has a fever".
NIWA said it was the warmest winter on record for the third year with the nationwide average temperature of 9.8 degrees Celsius - 1.4 degrees above the 1981-2010 average.
There were 84 locations, which experienced a record or near-record warm winter with wide-ranging temperatures with Wairoa, north of Napier, reaching 24.3 degrees - the second warmest August temperature - while Aoraki/Mt Cook dropped to a bone-rattling -11.6 degrees - the coldest winter temperature in two years.
It was also the wettest winter on record, which saw devastating floods when a state of emergency was declared in Nelson, Tasman, the West Coast and Marlborough, leaving the area with a massive cleanup on its hands.
Forty-two locations experienced a record or near-record wet winter with NIWA meteorologist Ben Noll saying climate change was having a significant impact.
"We feel like a broken record ... but this is mother nature's way of expressing she has a fever - she is running a higher temperature and it is pretty concerning to see that, successively, season after season," he said.
