Another scorcher is on the cards for much of the country today, as new records are set.
The Wellington suburb of Kelburn shattered a 90 year temperature record on Tuesday, hitting 30.3degC.
Many people may have also struggled to sleep overnight, with much of the North Island and the top of the South Island failing to drop below 20 degrees.
But there seems to be no let-up in sight - Blenheim and Te Kuiti are set to reach 33 degrees on Wednesday.
Service providers in Wellington are confident the rail network will be back on track after the hot weather affected services.
The wires that provides power to the overhead supply to the train network stopped working along the Hutt and Johnsonville lines at peak times on Tuesday.
Thousands of commuters were stranded and were forced to use buses to get home. KiwiRail says services are expected to return to normal this morning as temperatures fall.
Meanwhile, Tauranga City Council says water demand is up by 30 percent on normal use.
Sprinkler and hose restrictions are now in place, and spokesperson Steve Burton, says people are good at rationing supply.
"Our water usage in the city has perked up, we've reached a point now where we've got to curtail some of the outdoor water use," he said.
Many councils across the country are urging people to conserve water, as the heatwave continues.
