State of Emergency Declared in Wellington as Record Rainfall Triggers Severe Flooding and Evacuations

Porirua City Council

New Zealand has declared a state of emergency in its capital after intense rainfall triggered flash flooding, landslides, and widespread disruption across the city.

Authorities took the step following a sudden deluge that saw around 77mm of rain fall in less than an hour, overwhelming drainage systems and inundating streets, homes, and key infrastructure.

Emergency services responded to dozens of incidents overnight, including flooded properties, blocked roads, and damaged buildings. In some areas, residents were forced to evacuate as waters rose rapidly, while a search operation was launched for a missing person in one of the worst-affected suburbs.

Footage from across the city showed vehicles submerged, trees uprooted, and mudslides cutting off access to several neighborhoods. Officials warned that conditions could worsen, with more heavy rain forecast in the hours following the initial flooding.

Local authorities urged residents in low-lying and flood-prone areas to move to higher ground and avoid unnecessary travel. Schools were closed and flights disrupted as the city grappled with the impact of the extreme weather.

The flooding comes just days after other parts of New Zealand’s North Island were hit by severe weather linked to Cyclone Vaianu, compounding pressure on emergency response systems.

Emergency management officials said the declaration allows for better coordination of rescue efforts and access to additional resources, as crews continue to respond to calls for assistance and assess the extent of the damage.

Authorities have warned that the situation remains volatile, with further rainfall expected to test already saturated ground and strained infrastructure.
