Cyclone Vaianu, approaching New Zealand, could cause flooding in its most populous city Auckland, the nation's weather forecaster warned on ⁠Saturday, as authorities issued evacuation orders for parts of the country's North Island.

Vaianu, forecast to bring heavy rain and winds of up to 130 kilometres per hour, was expected to hit on Sunday, then pass west of the remote Chatham Islands on Monday, the weather forecaster said.

It warned that Auckland, a city of 1.7 million people, could expect up ⁠to 110 millimetres of rain from late ⁠Saturday to Sunday afternoon, with "heavy ⁠swells and coastal inundation likely".

"Streams and rivers may rise rapidly," it added.

Several North Island regions were under ⁠emergency declarations, including Whakatane, population ‌37,150, where authorities ordered evacuations in some coastal areas of the district.

"Residents should plan to be ‌away for at least two days," the Whakatane District Council posted on Facebook. ⁠On coastal areas, the storm could cause landslides, storm surges, waves of up to 13 metres and coastal flooding, it said.

About 180 km south, ‌in the Hawke's Bay region, authorities said they would start evacuating homes and public places in beachfront areas on Saturday afternoon.

Prime Minister Christopher Luxon said on Friday the cyclone had the potential to ⁠be damaging ‌and urged those in its path ‌to prepare for impact.

"Make sure drains are free, check in on the neighbours, and be prepared for ‌possible power cuts," Luxon said on X.

Vaianu has conjured up the painful memory of 2023's Cyclone Gabrielle, which killed 11 and displaced thousands in ⁠one of New Zealand's biggest natural disasters this century. (Reuters)
