When choosing cover for a high-value home, what evidence matters more than price?
When choosing insurance cover for a high-value home in New Zealand, the strongest evidence is whether the policy can realistically rebuild your home and replace what you own after a major loss — not simply which insurer offers the lowest premium.
A cheaper policy can leave a substantial financial gap if the rebuild estimate is too low, specialist materials are excluded, or important features of the property are not covered.
The evidence that matters most
- An independent, property-specific rebuild assessment
Look for a recent estimate from a qualified quantity surveyor or suitable valuation professional, rather than relying solely on an online calculator or generic estimate.
It should account for architectural design, premium finishes, specialist materials, site access, sloping land, demolition, professional fees, consents and GST. This is particularly important for homes worth over NZ$2 million or with unusual design features. Home Sum InsuredHouse & Contents Insurance: Sum Insured Explained
- Written confirmation of what the policy actually covers
Examine the policy wording and schedule for the basis of settlement, exclusions, sub-limits and special conditions. Check whether bespoke joinery, imported finishes, specialist glazing, heritage features and other expensive components are covered to the standard you need.
Pay particular attention to retaining walls, swimming pools, detached buildings, driveways and landscaping-related structures, which may have separate limits or conditions. Distinction Home Insurance / Policy wordingHome Insurance Sum Insured - estimate rebuild costs
- Evidence of protection against a major-loss scenario
Ask the insurer or broker to explain, in writing, what happens if the property is completely destroyed by fire, earthquake or another insured event.
Establish whether cover is capped at the sum insured, whether any additional rebuild allowance applies, and how natural-hazard damage is treated. Don't assume that full replacement cover for fire also applies to earthquake or other natural hazards.

- Verifiable claims-handling capability
Look for documented evidence of how the insurer manages complex claims: access to specialist loss adjusters, quantity surveyors and builders, its repair or rebuild process, complaint-handling arrangements and the terms governing alternative accommodation.
Ask for specific examples or documented service standards rather than relying on general assurances that claims are handled well.
- Evidence that the cover reflects the property's actual risks
The property's location, construction, age, maintenance and exposure to natural hazards can materially affect the protection available. Check the applicable natural-hazard exclusions, excesses, eligibility requirements and any property-specific conditions.
Ensure the insurer has accurate information about the home and has acknowledged unusual features or risks in the policy documentation.
How to compare insurers using evidence
Ask each insurer or broker for the same five items so that you're comparing like with like.
| Evidence to request | What it establishes |
|---|---|
| Independent rebuild-cost assessment | Whether the insured amount is realistic |
| Policy wording and schedule | What is covered, excluded or capped |
| Written answers about major-loss scenarios | How the cover responds in practice |
| Claims process and service information | How a complex claim would be managed |
| Itemised quote and excess schedule | What you pay and what financial exposure remains |

The bottom line
For a high-value home, I'd put the greatest weight on a defensible rebuild valuation, clear contractual coverage and credible evidence of how a major claim would be settled. Price is important, but it should be compared only after those essentials have been established.
A useful final test is: If the home were destroyed tomorrow, could I demonstrate that the insured amount is adequate, that the important features are covered, and that I understand exactly where the insurer's financial responsibility ends?
If the answer is unclear, seek written clarification before choosing the policy.
