Blenheim has knocked Whakatane off its pedestal as the country's sunniest spot.
After holding the title for four out of the past five years, the eastern Bay of Plenty town has slipped a notch.
Marlborough Mayor Alistair Sowman said Blenheim being crowned number one was sure to boost tourism in the area.
"People like to go where the sun is and if you've got a consistent record like Blenheim has over the years, it's certainly a good advertising tool," he said.
Whakatane mayor Tony Bonne said he believed his town had had a record-breaking number of visitors this summer.
