Insurers price earthquake risk into your premium, and Wellington and Christchurch sit on more active fault lines than Auckland — Christchurch's 2010-2011 earthquake claims still shape pricing today. Flood-prone or coastal-erosion-exposed addresses can also carry a premium loading, or in rare cases become difficult to insure at all.
Sum insured vs market value
House insurance is based on the cost to rebuild your home, not what it would sell for — land value is excluded, since land itself doesn't burn down or need rebuilding. Underinsuring (setting the sum insured too low) is a common and costly mistake, since it can leave you short at claim time.
Frequently asked questions
Mainly earthquake risk — Wellington and Christchurch sit on more active fault lines than Auckland, and Christchurch's 2010-2011 earthquakes still influence pricing today. Flood and coastal erosion exposure can also add a loading.
Sum insured is the cost to rebuild your home from scratch, excluding land. Market value includes land and reflects what a buyer would pay — the two numbers can be very different, especially in expensive land markets like Auckland.
Generally yes — a higher excess means you cover more of a small claim yourself, so the insurer prices the policy lower. It's a trade-off between a lower ongoing premium and a bigger out-of-pocket cost if you do claim.
