New Zealand endured a wet and cloudy January, with temperatures slightly below average, according to the National Institute of Water and Atmospheric Research.
Tauranga, Gisborne, Hawke's Bay, Wairarapa and Wellington received more than double their average January rainfall, climate scientist James Renwick says.
Of the six main centres, Tauranga was the warmest and sunniest, Hamilton the wettest, Dunedin the coolest and Christchurch the driest.
Blenheim recorded the highest temperature on 34.3 degrees Celsius on New Year's Day.
Dr Renwick says he expects westerly and south-westerly weather patterns to resume in February and March bringing high pressure systems to the north and some rain to the west and south.
