Compare house insurance for your Wellington property. Understand local earthquake risk, hillside hazards, and high wind exposure - then compare estimates from NZ's top providers. Wellington has the highest house insurance premiums in New Zealand.
Wellington is New Zealand's capital city, home to approximately 215,000 people in the city proper and around 425,000 across the wider Wellington region. Situated at the southern tip of the North Island on an active tectonic plate boundary, Wellington is one of the most seismically active capital cities in the world.
From an insurance perspective, Wellington is the most expensive region in New Zealand for house insurance. The combination of major active earthquake faults running through the city, steep hillside properties prone to landslips, extreme wind exposure, and tsunami risk for coastal suburbs means premiums here are significantly higher than the national average.
All major NZ house insurance providers - including AA Insurance, AMI, State, Tower, and Cove - offer cover for Wellington properties. However, premiums vary substantially between providers and between individual addresses, so comparing multiple quotes is essential. See our full NZ house insurance comparison for provider details.
Understanding local hazards helps you choose appropriate cover and calculate your sum insured accurately.
| Hazard | Risk Level | Details | Insurance Impact |
|---|---|---|---|
| Earthquake | Very High | Wellington sits on a major tectonic plate boundary with multiple active faults. The Wellington Fault runs directly through the city. The Ohariu Fault lies to the west and the Wairarapa Fault to the east. The Hikurangi Subduction Zone lies offshore. GNS Science estimates a roughly 10% probability of a magnitude 7.5+ earthquake on the Wellington Fault within the next 100 years. | Earthquake risk is the primary driver of Wellington's high premiums. Covered by the Natural Hazards Commission (NHC) up to $300,000 + GST per dwelling with a $250 excess. Private insurer covers amounts above the cap. |
| Landslip & Slope Instability | High | Wellington's steep topography means many properties are built on hillsides with retaining walls. Heavy rainfall events regularly trigger landslips across the city. The combination of steep terrain, weathered greywacke rock, clay soils, and high rainfall creates persistent slope instability risk. | Natural landslip is covered by NHC up to $300,000 + GST. Properties with LIM-noted slope hazard designations typically face higher premiums. Retaining wall cover is an important consideration for hillside homes. |
| High Winds | High | Wellington is one of the windiest cities in the world due to its position in the Roaring Forties wind belt and the funnelling effect of Cook Strait. Wind gusts regularly exceed 100 km/h, and gusts above 140 km/h have been recorded. Exposed ridgeline and hilltop properties are most affected. | Wind damage is covered by most comprehensive house insurance policies. Exposed properties on ridgelines may face higher premiums. Roof condition and cladding type affect risk assessment. |
| Tsunami | Significant | Coastal suburbs including Lyall Bay, Island Bay, Petone, and the Wellington waterfront are within tsunami evacuation zones. A large earthquake on the Hikurangi Subduction Zone could generate a tsunami reaching Wellington's coast within minutes. WREMO provides detailed evacuation zone maps. | Earthquake-generated tsunami damage is covered by the Natural Hazards Commission (NHC) up to $300,000 + GST. Private insurer covers amounts above the cap. |
| Flooding | Moderate - Significant | Low-lying areas in the Hutt Valley, Porirua, and parts of central Wellington are susceptible to flooding. Climate change is increasing rainfall intensity, and ageing stormwater infrastructure in some areas compounds the risk. The Hutt River has a history of significant flood events. | Flood cover comes from your private insurer (not NHC). Properties in identified flood zones may face premium loadings or higher excesses. Check Wellington City Council's hazard maps for your property. |
Disclaimer: Risk levels shown are general assessments based on publicly available hazard data. Your property's specific risk profile depends on its exact location, elevation, and proximity to hazard sources. Always obtain a current LIM report from Wellington City Council for property-specific hazard information.

Properties closer to the Wellington Fault, Ohariu Fault, or Wairarapa Fault face the highest seismic risk. Insurers use detailed GNS Science fault mapping to assess individual address risk, and proximity to active faults is a major premium driver.
Many Wellington homes are built on steep hillsides with retaining walls. Properties with LIM-noted slope hazard designations, or those requiring significant retaining structures, typically face higher premiums due to landslip risk and difficult access for repairs.
Older unreinforced masonry buildings face higher earthquake risk. Timber-framed homes generally perform better in earthquakes. Properties with outdated wiring, lack of insulation, or non-compliant building work face higher premiums.
Ridgeline and hilltop properties in Wellington face extreme wind exposure. Roof condition, cladding type, and the property's aspect relative to prevailing northerly and southerly winds all affect how insurers assess wind damage risk.
Accurately calculating your rebuild cost is essential. Use the Cordell Calculator or get a quantity surveyor's estimate. Wellington's steep sites and difficult access can increase rebuild costs significantly compared to flat-land builds.
Wellington has varied ground conditions. Properties on soft or reclaimed land (such as parts of the CBD and waterfront) face higher earthquake amplification risk than those on solid rock. Soil type directly affects how seismic waves impact your home.
Different areas within Wellington face different natural hazard exposures. Here is a general guide.
The CBD and inner-city area built partly on reclaimed land. Close to the Wellington Fault trace which runs along the base of the Terrace escarpment.
Elevated suburbs on the western hills. Kelburn is home to Victoria University. Karori is one of Wellington's largest suburbs by population.
Coastal suburbs on Wellington's south coast. Exposed to Cook Strait weather and within tsunami evacuation zones.
The Hutt Valley stretches northeast from Wellington Harbour. Lower Hutt and Upper Hutt together house over 150,000 people. The Wellington Fault runs along the valley's western edge.
Note: These are general observations only. Your property's specific risk depends on its exact address, elevation, and current hazard mapping. Always check your LIM report and consult your insurer for property-specific information.
Practical steps to protect your property and manage your insurance costs.
Secure heavy furniture, water heaters, and shelving. Keep an emergency kit with water, food, and supplies for at least seven days. Register with WREMO (Wellington Region Emergency Management Office) for alerts and know your nearest evacuation routes.
Wellington's steep sites, retaining walls, and difficult access can make rebuild costs significantly higher than flat-land builds. Use the Cordell Calculator and factor in site-specific costs. Review annually to account for rising construction costs.
Wellington premiums vary significantly between providers. Get at least 3 - 4 quotes, as insurers weigh earthquake, wind, and hillside risk differently. Address-level pricing means two homes on the same street can have very different premiums.
If your home is on a hillside, check your retaining wall condition regularly. Ensure your policy covers retaining walls and understand your excess for landslip claims. Request a current LIM report to see any slope hazard designations.
The Natural Hazards Commission covers earthquake, landslip, volcanic eruption, and tsunami up to $300,000 + GST. Flood damage to your building is covered only by your private insurer - not NHC. This distinction matters for properties in Wellington's flood-prone areas.
Insure your house and contents with the same provider. Multi-policy discounts of 5 - 15% are common across NZ insurers and can help offset Wellington's higher premiums.
