Wellington, New Zealand – Torrential rains battered the capital on April 20, unleashing flash floods and landslides that prompted authorities to declare a regional state of emergency.[1] The downpour, which dumped a record 77 millimeters of water in under an hour, caught many residents off guard and overwhelmed the city’s infrastructure.[1] This extreme weather came less than a week after Cyclone Vaianu ravaged parts of the North Island, compounding recovery efforts.[2]
A Downpour Unlike Any Other
Early on April 20, Wellington shattered rainfall records when 77mm fell in a single hour, the heaviest ever recorded in the city.[1] Mayor Andrew Little described the scene: “The wild weather continues. We’ve had flooding, slips and evacuations… The flooding has been strong enough to move cars, and many manhole covers have been lifted.”[1] Southern suburbs bore the brunt, with water surging through streets and gardens in areas like Mornington and Karori.
Fire and Emergency New Zealand handled over 180 calls between 3:30am and 11am for flooding and slips.[3] Videos captured cars floating away and roads turning into rivers, highlighting the rapid onset of the crisis.
Landslides and Floods Reshape Neighborhoods
Landslides struck multiple sites, burying roads and damaging homes in Vogeltown, Berhampore, and South Karori.[3] Around 10 houses became uninhabitable, forcing residents out amid ongoing threats.[3] In Mount Cook, floating vehicles perched on fences after the waters receded slightly.
Low-lying zones saw repeated inundations, with neighborhoods like Island Bay, Newtown, Brooklyn, and the Basin Reserve facing severe impacts.[3] One dramatic incident involved neighbors carrying elderly, blind residents from a flooded home barefoot through the deluge.[4]
- Island Bay: Flash flooding overwhelmed streets.
- Berhampore: Multiple homes damaged by slips.
- Mornington: Gardens and properties inundated.
- Newtown: Infrastructure strained by water surges.
- Brooklyn: Landslide risks heightened on hillsides.
Swift Emergency Measures Take Hold
At 2:30pm on April 20, the Wellington Regional Emergency Management Office activated the state of emergency, granting responders enhanced powers for coordination and safety.[3] Group controller Carrie McKenzie emphasized: “The priority is life safety. We are asking people to take this seriously, follow safety advice, and act early if they are in low-lying or flood-prone areas.”[4]
Evacuations targeted flood-prone spots, including Konini Street, Wetherby Street, and Rata Street in Wainuiomata.[3] Shelters opened at the Wellington City Mission and hubs in Lower Hutt, accommodating dozens displaced by the chaos. Police searched for 60-year-old Philip Sutton, missing after floods hit his Karori South Road home, though efforts paused overnight due to debris.[1][4]
Schools Shut, Travel Grounded
More than 100 schools and kura across Greater Wellington closed, impacting 42,762 students, while 161 early childhood centers also shuttered.[5] Universities like Te Herenga Waka-Victoria halted operations until Wednesday.[3] One school, South Wellington Montessori, sustained contamination from floodwaters, rendering it unsafe.
Wellington Airport canceled at least 28 flights, with more disruptions likely.[3] Roads like State Highway 2, Riverside Drive, and Liardet Street faced closures from slips and water, while all Metlink ferries suspended service.
Forecasts Warn of Prolonged Threat
MetService issued red heavy rain warnings for Wellington and Wairarapa until Tuesday night, predicting 100-150mm more in eastern hills and up to 280mm in coastal areas.[3] Minister for Emergency Management Mark Mitchell urged preparation: “If you are in the Wellington region, be prepared… make those decisions early.”[1]
Risks persisted for further slips, river rises, and isolation of communities, prompting calls to clear gutters, check neighbors, and avoid floodwaters at all costs.
