The Natural Hazards Commission [NHC] is now dealing with more landslide-related damage claims than claims for any other natural hazard, highlighting the growing cost of unstable land and extreme weather events.
Nearly 13,000 landslide claims were lodged over the past five years, an increase of 10,000 compared with the previous five-year period.
“Landslides can happen with little warning and cause significant damage to homes and property and, in some cases, put lives at risk,” NHC chief executive Tina Mitchell said.
She said that as storms become more frequent and severe, landslides are becoming an increasing concern for communities across the country.
Mitchell said it was important for homeowners to understand the risks in their area and take practical steps to better protect and strengthen their properties.
“Regular maintenance, good drainage, and getting expert advice early can make a real difference,” she added.
“If you have concerns about retaining walls or slope stability, a geotechnical engineer can help assess risks and recommend next steps.”
Kiwis living on or near slopes are being urged to watch for warning signs of instability, including ground cracks, leaning retaining walls, and noticeable land movement after heavy rain.
She said it was also important for homeowners to understand exactly how their insurance cover works so they can make informed decisions about strengthening their property and preparing for any gaps in coverage.
For prospective homebuyers, NHC recommended checking the Natural Hazards Portal for records of previous claims linked to landslides or other natural hazards, as these may provide an indication of future risk.
Mitchell said understanding a property’s exposure to natural hazards before a disaster occurs could help homeowners reduce stress and avoid greater financial pressure later on.
