The 2026 granny flat reforms in New Zealand will allow a second dwelling of up to 70 square metres on most residential and rural-zoned properties without building consent, provided certain criteria are met. For a property owner looking to add a tiny home on their land, that change could mean the difference between a structure that qualifies for standard home insurance and one that sits outside the system entirely. The reforms split the tiny house movement into two tracks — one for fixed, consented homes that can be mortgaged, insured, and legally recognised, and another for wheeled homes that remain in a grey zone with less visibility, less protection, and more risk.

Which track your tiny home falls into determines what insurance you can get, what it costs, and whether a lender will even touch it. The reforms are meant to make small homes more accessible, but they also create a divide that leaves wheeled homes in a riskier position. Property owners who own land can take advantage of the new rules, while those without land remain reliant on workarounds that carry more uncertainty. Here’s what you actually need to know.
Four things to know about tiny home insurance after the 2026 reforms
One term you’ll hear a lot in this space is consent-exempt dwelling — a second home of up to 70sqm that doesn’t require building consent under the 2026 reforms, provided it’s on a qualifying property and meets the criteria. That label is what separates a structure insurers recognise as a standard home from one they treat as a vehicle or temporary structure.
What I’d do first: look at your property’s zoning and check whether the 70sqm threshold applies before you buy or build anything. That single number decides which track you’re on. Understanding home insurance regulations in New Zealand will help you see how the system treats different dwelling types.
The 70sqm threshold and what it costs you in insurance terms
The 2026 reforms set a clear size limit: any second dwelling up to 70 square metres that meets the criteria can be built without building consent. Stay under that number and you’re on Track 1 — a fixed, consented home that can be financed, insured, and legally recognised. Go over it, or put your home on wheels, and you’re on Track 2 — less visibility, less protection, more risk.

| Feature | Track 1 — Fixed, consented | Track 2 — Wheeled or unconsented |
|---|---|---|
| Building consent required | No (under 70sqm, criteria met) | Usually yes, or grey zone |
| Standard home insurance | Available | Rarely available |
| Mortgage eligibility | Yes — lenders recognise it | Unlikely — no standard policy |
| Legal recognition | Full — council sign-off possible | Limited — often treated as a vehicle |
What that means in cash terms: a Track 1 tiny home can be insured under a standard residential policy, typically costing a few hundred dollars a year depending on location and rebuild value. A Track 2 wheeled home often requires a specialist insurer or a caravan policy, which can cost more and offer less coverage — especially for contents, liability, and storm damage. If you’re on rural or flood-prone land, those differences widen further.
What I’d do: measure your planned tiny home against the 70sqm limit before you commit to a design. If you’re considering a wheeled model, securing insurance on high-risk properties is a useful read — the same principles apply to non-standard dwellings.
Where property owners get tiny home insurance wrong
Assuming wheeled homes are covered by standard home insurance
This is the most expensive mistake. A wheeled tiny home is structurally a vehicle in the eyes of most insurers. If you try to claim under a standard home policy, you’ll likely be declined — and you’ll have paid premiums for nothing. The fix is to approach specialist insurers or caravan and motorhome specialists who understand the product. JustAnswer Real Estate Law can help clarify the legal classification of your dwelling if you’re unsure.
Ignoring the 70sqm consent threshold
Some owners build slightly over 70sqm thinking it won’t matter. It does. Crossing that limit means you lose the consent exemption, which means the dwelling isn’t recognised as a standard residential structure, which means insurers won’t treat it as one. The cost difference in premiums and coverage can be substantial. If you’re close to the line, keep the design under 70sqm.
Not understanding that financeability drives insurance requirements
Lenders require insurance before they release funds. If your tiny home can’t get a standard policy, you can’t get a mortgage. That limits your options to cash purchases or specialist lenders charging higher rates. The 2026 reforms make Track 1 homes financeable — but only if you meet the criteria. If you’re planning to rent out the tiny home for extra income, you’ll also need landlord-style cover, which adds another layer.
What I’d do: check with your insurer before you build, not after. A quick call to confirm they’ll cover a consent-exempt dwelling under 70sqm saves you finding out later that you’re uninsurable. Navigating payout disputes is worth knowing about if you ever need to challenge a declined claim.
How to insure a tiny home in New Zealand after the 2026 reforms
Track 1: Getting insurance for a fixed, consented tiny home
If your tiny home is under 70sqm, on a qualifying residential or rural-zoned property, and meets the consent-exemption criteria, you can insure it through any standard home insurer. The process is straightforward: get a rebuild valuation, choose your level of cover (building only, or building plus contents), and add liability protection. Most insurers offer online quotes, but it’s worth speaking to a broker who understands the new rules. Make sure you mention the consent-exempt status — some insurers may still ask for evidence that the dwelling meets the criteria.
Track 2: Insuring a wheeled tiny home
Wheeled homes are trickier. Standard home insurers will typically decline them because they’re not fixed to the land. Your best options are specialist insurers who cover caravans, motorhomes, or “non-standard” dwellings. These policies tend to cover the structure, contents, and liability, but may exclude certain risks like storm damage or theft from an unoccupied site. Some providers also require the home to be on a registered site or connected to services. Shop around — premiums vary widely, and coverage terms differ from one insurer to the next.
What the 2026 reforms mean for your insurance strategy going forward
The reforms are due to take effect in 2026, which means the rules around consent exemptions, council sign-off, and lender recognition will shift. For property owners who own land, the opportunity is clear: a fixed, consented tiny home under 70sqm can be treated as a proper dwelling. For those without land, the wheeled model remains a viable option but carries more insurance risk and less legal protection. If you’re planning a tiny home, the smartest move is to choose your track early and build your insurance approach around it.

The 2026 reforms create two paths — make sure you’re on the right one
The split between Track 1 and Track 2 is real, and it’s not going away. Property owners who own land and build a fixed tiny home under 70sqm will have access to standard insurance, mortgage finance, and full legal recognition. Those who choose a wheeled home will need to work harder to find cover, and will face more risk and less protection. The 2026 reforms don’t solve that problem — they make the gap more visible. If you’re planning a tiny home, the most important decision you’ll make is which track you’re on, and the most important step is getting your insurance sorted before you build or buy.
