Flood in New Zealand

A significant severe weather event is impacting the lower North Island of New Zealand, including Wellington (excluding Porirua), Wairarapa, and the Tararua District. A slow-moving low-pressure system linked to Cyclone Vaianu is bringing prolonged heavy rain, thunderstorms, and strong winds.

MetService warnings indicate widespread rainfall of 80–120 mm, with up to 200–280 mm in elevated areas such as the Tararua Range, and peak intensities of 25–40 mm per hour. Red and Orange Heavy Rain Warnings highlight a high risk of flooding, rapid river rises, landslides, and significant disruption, exacerbated by already saturated ground conditions.
