Home insurance is not optional if you have a mortgage — banks require you to hold current house insurance as a condition of lending. Understanding what insurance costs and what affects your premium helps you budget accurately and choose the right cover.
How Much Does House Insurance Cost in NZ?
House insurance premiums vary widely depending on location, construction type, and sum insured. Indicative annual premiums:
| Property type and location | Indicative annual premium |
|---|---|
| Standard suburban home, Christchurch/Canterbury | $1,800–$3,200 |
| Standard suburban home, Auckland | $1,500–$2,800 |
| Standard suburban home, Wellington | $2,500–$5,000+ |
| Standard suburban home, other NZ cities | $1,200–$2,500 |
| Timber frame (lower risk construction) | Typically lower |
| Brick/masonry (higher seismic risk) | Typically higher |
| Properties with flooding/landslide risk | 20–50%+ premium |
Wellington is notably more expensive due to earthquake risk. Some Wellington properties (particularly older masonry construction) can have premiums of $5,000–$8,000+ per year.
What Affects Your House Insurance Premium?
| Factor | Effect on premium |
|---|---|
| Location | Major factor — seismic zone, flood zone, crime statistics |
| Construction type | Timber < brick/masonry for earthquake risk |
| Sum insured (rebuild value) | Higher sum = higher premium |
| EQC levy | Set amount per year ($345/year as at 2026, applied to home policies) |
| Age of property | Older properties may cost more |
| Excess (deductible) | Higher excess = lower premium |
| Security features | Alarm systems may provide a small discount |
Sum Insured: Rebuild Cost vs Market Value
Critical point: Home insurance in NZ is now typically sum-insured (you specify the rebuild cost), not replacement value (insurer pays whatever it costs). Getting this figure wrong — too low — means you’re underinsured.
The rebuild cost is not the same as the market value:
- Market value includes land (which doesn’t burn down or need rebuilding)
- Rebuild cost includes demolition, materials, labour, and consent costs for a modern compliant home
How to estimate your rebuild cost:
- Use your insurer’s rebuild calculator (all major NZ insurers have these)
- Check the QV rebuild cost estimate on your rates notice (a starting point, not definitive)
- Commission a registered valuer to provide a rebuild cost estimate ($500–$1,000) for high-value or unusual homes
Underinsurance risk: If you’re 20% underinsured and make a claim, many policies will only pay 80% of the claim — leaving you with a significant shortfall.
EQC (Earthquake Commission) Cover
The EQC — now operating as Toka Tū Ake — provides base natural disaster cover for all insured residential properties in NZ:
- EQC cover: Up to $300,000 plus GST (as at 2024) for damage from earthquake, volcanic eruption, geothermal activity, tsunami, landslip caused by natural event, or storm/flood damage to land
- EQC levy: $345/year (included in your private insurance premium, collected by insurers and passed to EQC)
- Excess: You pay an excess; the EQC pays the rest up to the cap
- Above the cap: Your private insurer covers damage above the EQC cap
For high-value properties, ensure your private insurance picks up from where EQC ends ($300k + GST).
Contents Insurance
Separate from house insurance, contents insurance covers your personal belongings.
Indicative annual contents insurance costs:
| Coverage level | Typical annual premium |
|---|---|
| Low coverage ($40,000) | $400–$700 |
| Medium coverage ($80,000) | $600–$1,200 |
| High coverage ($150,000+) | $1,000–$2,000+ |
Contents insurance is important but sometimes skipped — the cost of replacing furniture, appliances, clothing, and electronics in a major loss can easily exceed $50,000–$100,000 for a family home.
Getting the Best Deal on Home Insurance
- Compare at least 3 providers — IAG (State/AMI), Tower, AA Insurance, Vero, FMG (rural), NZI
- Use a broker — insurance brokers can access products not available directly and compare across multiple insurers
- Increase your excess — a $500 excess vs $250 can reduce your premium by 10–20%
- Bundle house and contents — many insurers offer discounts for combined policies
- Reassess sum insured annually — rebuild costs have risen significantly since 2020 due to construction inflation
When to Get an Insurance Quote
Get an insurance quote before you go unconditional on a property. If you discover at this stage that the property is uninsurable or only insurable at a prohibitive premium (e.g., some Wellington properties), you can still exit on the basis that the property is not financeable.
Banks require proof of current insurance before releasing settlement funds.
