Home insurance in New Zealand is compulsory in practice even where it isn’t legally mandatory — your mortgage lender will require it as a condition of your home loan. But beyond ticking the lender’s box, understanding what your policy actually covers (and what it doesn’t) is critical, especially given New Zealand’s earthquake risk.
Every NZ homeowner needs building (home) insurance. Get replacement-value cover, set the sum insured accurately using a rebuild cost estimator, and understand that EQC provides the first layer of earthquake cover up to $300,000 for buildings. Bundling home + contents typically saves 5–15% vs buying separately.
Building Insurance vs Contents Insurance
| Type | What It Covers |
|---|---|
| Building (home) insurance | The structure: walls, roof, floors, foundations, built-in fixtures, plumbing, wiring |
| Contents insurance | Your possessions: furniture, electronics, clothing, appliances |
| Combined home + contents | Both — usually with a discount |
Renters only need contents insurance (the building is the landlord’s responsibility). Homeowners need both.
EQC — New Zealand’s Unique Earthquake Cover
The Earthquake Commission (EQC) provides the first layer of natural disaster insurance for residential properties in New Zealand. This is funded by a levy on home insurance policies.
What EQC covers:
- Earthquake, volcanic eruption, tsunami, hydrothermal activity, natural landslip
- Buildings: up to $300,000 (plus GST) per event
- Contents: up to $20,000 (plus GST) per event (for natural disasters)
How it works in practice:
- You buy home insurance from a private insurer (AA, AMI, State, Tower, etc.)
- Your insurer collects the EQC levy as part of your premium
- If a covered natural disaster damages your home, EQC covers the first $300,000 of building damage
- Your private insurer covers damage above $300,000
The 2010–2011 Canterbury earthquakes were a masterclass in why this matters. Many homeowners found the EQC/insurer boundary complicated — make sure you understand both layers.
Sum Insured — Getting It Right
Modern NZ home insurance policies are sum insured — you specify the maximum amount the insurer will pay to rebuild your home. Getting this wrong has serious consequences:
- Underinsured: If your rebuild cost exceeds your sum insured, you cover the gap yourself
- Overinsured: You pay higher premiums than necessary (though the insurer will generally only pay actual rebuild cost)
How to set your sum insured:
- Use the BRANZ Rebuild Cost Calculator or your insurer’s online tool
- Include demolition and site clearance costs (often 15–20% of rebuild cost)
- Include professional fees (architect, engineer, consents)
- Don’t use your purchase price or market value — rebuild cost is different, especially for unique or older homes
A 200m² Auckland home typically has a rebuild cost of $500,000–$800,000, well above what many people set as their sum insured.
What Home Insurance Covers
Typically included:
- Fire and smoke damage
- Natural disaster (via EQC levy)
- Storm, flood, and burst pipe damage
- Theft or burglary (structural damage, e.g., broken windows/doors)
- Accidental breakage (glass, sanitary fixtures — check policy)
- Liability for injuries occurring on your property
Typically excluded:
- Gradual damage and rot (lack of maintenance)
- Earthquake damage to flat land (TC3 land in Canterbury — complex — get specific advice)
- Business activities from home (check policy)
- Damage caused by tenants (need landlord insurance — see Landlord Insurance NZ)
Flood Risk in NZ
Flood risk is increasingly important after events like the 2023 Auckland floods and Cyclone Gabrielle. Some insurers are restricting flood cover or increasing premiums in high-risk zones.
Before buying a home, check:
- The property’s flood plain status on the council GIS maps
- Whether the insurer will offer full flood cover at an acceptable premium
Canterbury TC3 Land
Christchurch homeowners on TC3 (potentially unstable land) face specific challenges. Some insurers have restricted cover or added loadings. Always disclose your land category to your insurer and get clarification on what’s covered.
Bundling Home + Contents
Most NZ insurers offer a 5–15% discount when you bundle home and contents on the same policy. This is usually worthwhile — both in savings and the simplicity of dealing with one insurer at claim time.

Before Settlement Day
Your home insurance must be in place from settlement day — the moment ownership transfers to you. Don’t leave this until the week of settlement.
Steps before settlement:
- Get home insurance quotes 2–3 weeks before settlement
- Calculate sum insured using a rebuild cost estimator
- Notify your solicitor of your insurer (they’ll need this for the title transfer)
- Set up contents insurance for moving day
