Building Insurance — NZ Guide
Building insurance covers the structure and fixed fittings of your commercial premises—the physical building itself. This is essential if you own the building; if you rent, your landlord typically insures it. Coverage includes fire, water damage, natural disasters (earthquakes, storms), weather events, and accidental damage. The premium is calculated as a percentage of the rebuild cost—typically 0.1–0.3% annually. For a building valued at NZ$500,000, you might pay NZ$50–150 per month. Always ensure your cover amount matches the actual rebuild cost, not just the market value of land and building.
What's Covered
Rebuild Cost vs Market Value
Insurance companies calculate premiums and cover based on rebuild cost—the expense to reconstruct the building with similar materials and standards. This is often higher than market value (which includes land). If you underestimate rebuild cost, you'll be underinsured. Always have a professional assess rebuild cost separately from property valuation.
Fixed Fittings and Improvements
Building insurance typically covers the structure, roof, walls, fixed fittings (built-in benches, shelving, lighting), and permanent fixtures. It usually excludes contents (movable items) and vehicles. Discuss what counts as "fixed" with your insurer.
Natural Disaster Cover in New Zealand
New Zealand is earthquake-prone. Standard building policies may exclude earthquake or natural disaster damage. Ensure your policy explicitly covers earthquakes, landslips, volcanic eruption, and severe weather. This is non-negotiable in NZ.

Frequently Asked Questions
Do I need building insurance if I own my workshop?
Absolutely. If the building burns down or is damaged, you're responsible for rebuilding. Building insurance covers this critical risk. Most mortgage lenders require it as a condition of the loan.
What's the difference between rebuild cost and market value?
Market value is what you could sell the land and building for. Rebuild cost is the expense to reconstruct a similar building. These are often very different. Always insure based on rebuild cost to avoid underinsurance.
Does building insurance cover earthquake damage?
Some policies include earthquake; others exclude it. In New Zealand, natural disaster cover (including earthquake) should be explicitly included. Always confirm this is covered before taking out a policy.
What if I rent my premises—do I need building insurance?
No—your landlord insures the building. You need contents insurance to cover your equipment and stock. Clarify with your landlord who insures what.
How is building insurance premium calculated?
Premiums are typically a percentage of rebuild cost (0.1–0.3% annually, depending on building age, construction, location, and risk). A NZ$500,000 rebuild cost might cost NZ$500–1,500 annually.
