There is no single "average" body corporate premium in New Zealand — pricing is built up from the building's specific risk profile and the insurer's appetite for that risk. The drivers below are how every NZ underwriter (NZI, QBE, AIG, Zurich, Delta, Dual) rates a body corp risk.

## Sum insured drives the base premium

The largest single input is the **sum insured** — the cost to rebuild the building including demolition, professional fees, and code-compliance upgrades. NZ underwriters expect a current insurance-replacement valuation (typically every 2–3 years) from a registered quantity surveyor. The premium is a rate per $1,000 of sum insured, modified by every other factor below.

## Location (seismic + flood)

Wellington and Christchurch carry the highest earthquake loadings because of seismic zoning under the **NZS 1170.5** structural standard. NHC covers the first NZ$345,000 + GST per dwelling for natural-hazard damage; the private layer above sits at a higher rate per dollar in these zones. Coastal and river-flat addresses in Auckland and Hawke's Bay attract flood loadings post-Cyclone Gabrielle.

## Age + construction type

Buildings of certain era and construction (pre-1970s unreinforced masonry, leaky-building era timber-framed 1994-2004, multi-storey with EIFS cladding) attract higher rates or exclusions. Modern post-2011 builds to current code typically rate best.

## Claims history

The body corporate's own claims experience over the past 5 years materially affects pricing. A clean record can attract a no-claims discount; multiple weathertightness or water-ingress claims will move underwriters off the risk entirely.

## Why the long-term maintenance plan matters

Underwriters increasingly ask to see the **Long-Term Maintenance Plan** (required by the Unit Titles Act 2010). A well-funded LTMP signals lower forward claims risk; an underfunded one with deferred works flags the opposite.

## Excess + co-insurance

Earthquake excess is typically a percentage of sum insured (often 2.5%–10%), not a flat dollar amount. Increasing the excess lowers the premium; under-insurance triggers co-insurance penalties at claim time.

## Frequently asked questions

### How much does body corporate insurance cost per unit?

There is no fixed per-unit cost — it depends on the building's sum insured, location, age and construction type. As a directional point, insurance commonly accounts for 40–60% of the total body corporate levy on older or seismically-exposed NZ buildings. Ask your body corporate manager for the current premium and levy breakdown.

### Why did our body corporate insurance go up so much in 2026?

NZ commercial-strata premiums have hardened since 2022 driven by global reinsurance costs, the EQC → NHC scheme transition, Cyclone Gabrielle losses in Hawke's Bay and Auckland, and tightened underwriter appetite for leaky-building-era multi-unit risks. Most NZ body corporates have seen 15–40% step-ups over the period.

### Can we lower the premium without dropping cover?

Common levers: increase the earthquake excess (biggest single saving in Wellington/Christchurch), commission a fresh insurance-replacement valuation if the existing one is over 3 years old, document recent capital works, share the long-term maintenance plan with the insurer, and re-broke at renewal across the full NZ panel.

### Does excess apply per claim or per unit?

Per claim. Earthquake excess is typically expressed as a percentage of the building's sum insured (commonly 2.5%–10%); fire/storm/accidental excesses are typically a flat dollar figure. Confirm both on your schedule of insurance.
