A major homeware retailer has sold out of fans at some stores after a record-breaking heatwave in parts of the Bay of Plenty.
The average temperature in Whakatāne was 21.6C in January – the highest since records began in 1974, according to the National Institute of Water andAtmospheric Research (Niwa).
Tauranga, with an average temperature of 21.3C, had its fourth-highest January temperature since 1913 and Rotorua had an average temperature of 19.1C which was 1.4C higher than average.
People have reportedly been heading to retail outlets in a bid to combat the “warm, muggy and sultry nights”.
Briscoe Group managing director Rod Duke said its homewares shops were “very short of fans” and had “sold out in some stores after the record-breaking heatwave experienced in the Bay of Plenty”.
Duke said as residents try to keep cool at night the store was “unable to secure back-up supply” of fans or air purifiers.
Niwa said in a media statement that “out of the six main centres [cities] in January 2024, Auckland was the warmest and driest, Christchurch was the sunniest, Dunedin was the coolest and least sunny, and Tauranga was the wettest”.
“It was the hottest January on record for Whangaparāoa, Whakatāne, and Waikeria”.

Niwa meteorologist Ben Noll said “the overarching message is that most of New Zealand has experienced either above or well-above-average temperatures over the month to date”.
Niwa considered well-above-average anything above 1.2C – but many centres had sweltered in heat in excess of that mark.
“We’re not just talking one or two regions, but most of the country,” Noll said.
“Sea surface temperatures near the coast are higher than normal. Being an island nation our air temperatures are influenced by the surface temperature of the sea.”
Macara said global temperatures were steadily increasing overall which increased the odds of locations observing record or near-record high temperatures.
“There will increasingly be periods of cooler nights as we transition away from summer.
“The daylight hours shorten providing more time for overnight cooling.”
“While our daytime temperatures didn’t quite make a record, the highest last month in Whakatane was 30C compared to 33.3C in 2019.”
Law said the warm nights were a key factor in the overall monthly temperature statistic.
He said “warm, muggy and sultry nights” helped raise the overall average temperature for the time of year.
Tauranga reported a minimum temperature of 21.6C on January 20 – the same temperature as the “warmest night on record at that station since 1941″.
“The other factor that many people will have noticed last month was the high humidty which remained over the Bay, and much of the North Island, during the month.”
He said there was a “change on the cards this weekend” with “a much cooler night in store for Sunday night and the early hours of Monday morning”.
