Tiny House on Wheels Insurance NZ: What You Need to Know

Tiny houses on wheels are a unique asset — part home, part vehicle, and entirely outside the neat boxes that mainstream insurers have designed their products for. If you own one in New Zealand, here's what you need to understand about insuring it properly.

The Insurance Gap

The problem with tiny homes on wheels is that they fall between two traditional insurance categories:

**It's not a house** (in the eyes of most standard home insurers) because it doesn't have a permanent foundation, may not have a rateable value, and moves from site to site.

**It's not a caravan or trailer** (in any meaningful insurance sense) because the values are much higher, it's used as a full-time primary residence, and the construction is fundamentally different from a recreational vehicle.

This gap means many owners end up with either no insurance, inadequate insurance, or insurance from an insurer that will find reasons not to pay at claim time.

Two Covers Working Together

For a tiny home on wheels, you typically need two distinct covers working together:

1. Building Insurance (When Stationary)

When your home is parked on a site — whether that's private land, a tiny home village, a campground, or a holiday park — it needs building insurance that covers the structure for fire, storm, flood, earthquake, theft, vandalism, and accidental damage.

The key requirements:

- The insurer must specifically accept that the home is on wheels (not a permanent foundation)

- The sum insured must reflect the actual replacement cost, not market value

- The policy must not have an exclusion for non-standard construction if your home uses non-standard materials

2. Transit Cover (When Moving)

When your home is being towed — whether by you or a professional transporter — a separate transit policy should cover it for damage that occurs during transport. This includes structural damage from road vibration and movement, accident or collision damage, overturning, and loading and unloading damage.

Some building insurers extend their policy to cover transit automatically, but this needs to be explicitly confirmed in the policy wording.

Legal Requirements for Towing in NZ

If your tiny home on wheels exceeds 3,500kg Gross Vehicle Mass, it's classified as a heavy trailer under New Zealand law and requires a Certificate of Fitness (CoF) rather than a Warrant of Fitness (WoF). Additionally, maximum dimensions are: width 2.55 metres, height 4.25 metres, length 12.5 metres.

An overdimension permit may be required for larger homes, and specific conditions may apply around towing hours and routes. These compliance requirements are often conditions of your transit insurance policy.

Getting Insurance in New Zealand

The practical path to insurance is through a specialist broker. This type of insurance is a niche product — not every insurer offers it, and those that do have varying appetite and policy conditions. An experienced adviser will know which market will accept your specific home and can arrange the right combination of building and transit cover.
