Wellington declares a state of emergency following torrential overnight rains that deliver the heaviest downpour ever recorded in New Zealand’s capital. Authorities order evacuations in low-lying areas as flash floods and landslides force road closures across the city.
Mayor’s Urgent Warning
Mayor Andrew Little describes the event as unprecedented, noting the city received 77mm of rain in under an hour. “You’ll be aware there has been serious downpour in Wellington, particularly in the southern suburbs overnight, very serious flooding in many places,” he states on social media. “A lot of that flooding was the stormwater system being overwhelmed.”
While much of the water dissipates, surface flooding persists in several spots. The mayor advises residents to avoid unnecessary travel. “So this is a day to be really careful if you’re going out and about. If you can avoid travel, then please do so, but if you have to travel, then be very careful,” he urges.
Emergency Response Escalates
Emergency teams handle over 150 weather-related incidents, including home flooding and landslides in suburbs such as Newtown, Island Bay, and Kingston. Fire and Emergency New Zealand activates its regional coordination center to bolster operations.
Deputy national commander Megan Stiffler warns of rapid flood development. “Floods and flash floods can happen quickly. If you see rising water, do not wait for official warnings,” she says. “Do not try to walk, play, swim, or drive in floodwater. Do not drive through floodwater. You are putting yourself at risk, and risking the lives of those who come to your rescue.”
Wellington Civil Defence Emergency Management Group joint committee chair Anita Baker highlights the ongoing dangers. “This is a serious weather event with ongoing and evolving risks,” she explains. “The state of emergency gives responders the powers and coordination needed to keep people safe, support evacuations where required, and manage impacts across the region.”
Additional Hazards and Forecasts
Some neighborhoods experience up to 22mm of rain in brief bursts, marking the worst deluge residents recall. Search efforts continue for a man missing near a flooded property in Karori.
Heavy rain warnings persist for Wellington and Wairarapa until Tuesday night. Meteorologist Katie Lyons cautions about heightened risks. “Following the severe downpours over the last few days and the upcoming forecast rainfalls, there is an increased threat to life from dangerous river conditions, significant flooding and slips, with especially hazardous driving conditions,” she notes. “Some roads may become impassable, isolating communities.”
Dangerous seas threaten Wellington’s south coast. Chief scientist Dr. Emily Lane of Earth Sciences NZ explains pluvial flooding dynamics. “The intense rainfall over the past few days has caused what is known as pluvial flooding. Cities like Wellington tend to have a high proportion of impermeable surfaces where water can’t soak into the ground. Instead the water relies on stormwater systems to dissipate. But when the quantity of water is more than a stormwater system can handle, the excess water will follow overland paths to flow towards the sea.” She adds that such intense, localized events are projected to rise with climate change.
Community Impacts
Several schools close amid flooding, slips, and evacuations. The mayor emphasizes vigilance as another weather system approaches. “We’ve had flooding, slips and evacuations. There’s another big weather system moving in this afternoon, so we need to just stay alert and be prepared,” he says. “I’m taking this very seriously, and so is our whole region.”
