Another scorcher to start week with highs of 30c
Aucklanders stripped down to their undies and cuddled up to ice-cold water bottles after a Sunday scorcher became too hot to handle.
North Islanders are likely to be starting the working week on little sleep thanks to hot, muggy conditions.
MetService said Auckland and Wellington temperatures were between 18 and 20 degrees Celsius overnight. Auckland's daytime high on Sunday was 29C, but the agency's "Your Weather" page, which displays readings from home weather stations, showed temperatures of up to 32C around the city.
Meteorologist Leigh Matheson said humid spells were "not really unusual" at this time of year, which isn't comforting for Aucklanders who struggled to catch a bit of shut-eye on Sunday night.
Cool customers snap up fans
Briscoes spokesman Rod Duke said there has been a significant increase in the sale of fans.
"Sales have been very much larger recently than what is usual for this time of the year,
"It [fan sales] is more pronounced in the North Island than the South Island," Duke said.
Harvey Norman General Manager (small appliances) Evan Claxton said he has also seen fans flying of the shelves.
"There has definitely been an increase in the foot traffic regarding fans. Especially in the North Island."

"Sales have really been impacted last week with the high temperatures," Claxton said.
Aucklander Camille Rees said she was sleeping with freezing cold bottle of water to combat the heatwave, while @Dannews took to Twitter to suggest the invention of an electric blanket that keeps the bed cold.
And radio DJ Dominic Harvey admitted to stripping down to his undies at a barbecue.
Still so hot! I wonder how many Aucklanders are sitting in only their undies right now. I'm the only one at our BBQ doing it.— Dominic Harvey (@DomHarvey) January 24, 2016
The start of the week is likely to see more North Islanders spending evenings in their underwear, with the humidity due to stick around until later in the week.
Meanwhile, severe weather warnings are in place for heavy rain for Fiordland and Westland. Significant falls are also forecast for the Otago and South Canterbury headwaters.
The rain down south is set to move slowly eastwards over the South Island on Monday and Tuesday. Starting from Southland, it will spread up into Otago, Canterbury, and eventually Marlborough.

"Not a lot of rain, just outbreaks, spreading north," Matheson said.
Thick cloud will cover Canterbury on Monday, with Christchurch expected to reach 27C.
Further north, the remains of Cyclone Victor will continue to move southwest from near Raoul Island towards New Zealand.
On Monday, the capital will get fine afternoon spells with a high of 22C.
The central North Island is looking mainly fine with temperatures pushing 30C in some parts.
Auckland may get the odd shower between fine spells. A high of 27C is expected.
As Cyclone Victor comes down it will encourage an easterly flow, bringing showers and more humidity on Tuesday.
Southerlies coming through on Wednesday will cool temperatures in the lower North Island.
Showers will stick around until Thursday with possible outbreaks of rain along the eastern coast. Southerlies will then strengthen, particularly in Wellington.
