Most people think about home insurance as a price. The premium goes up, you grumble, you pay it or you shop around. That has been the whole conversation for years.



There is a second conversation starting in New Zealand, and it is about whether cover is available at all. In some flood-exposed areas, at least one major insurer has stopped writing new home policies. The insurance industry has said the money for flood protection and resilience has to be found, and the decision on who pays was not made before the election.

The short answer: if you own a home on the Hibiscus Coast or anywhere near water, this matters to you even if your premium has only risen modestly. Availability of home insurance in flood risk areas of NZ is now being decided property by property, on current hazard data, and the funding question that would change that sits with the next government. Here is what that means and what is worth checking now.

What is the difference between a premium rising and cover being withdrawn?

A premium rising is the insurer saying your home costs more to cover. Cover being withdrawn, or an insurer declining to write new policies in an area, is the insurer saying it already has as much exposure to that risk as it is prepared to carry.

The second is a different problem. You can shop around a high premium. You cannot shop around an area that several insurers have quietly capped.

The distinction matters because the first is visible on your renewal notice. The second you usually find out about when you try to buy or sell.

Has an insurer actually stopped writing new policies in New Zealand?

Yes. In January 2026, a major insurer stopped offering new home and landlord policies in the Westport postcode, citing flood risk. Existing customers kept their cover. New buyers in the area could not get a policy from that insurer, and the company said it would reopen only if its flood exposure fell below its limit.

Westport is a long way from Silverdale, and it is tempting to file this under "someone else's problem". That misses the point. The mechanism is the same everywhere: an insurer looks at its exposure to a hazard in an area, decides it has enough, and stops. It happened in one town this year. The tools that let an insurer do it exist for every postcode.

Why has adaptation funding been left to the next government?

Because it is expensive and nobody has agreed who pays.

When the Government introduced climate adaptation legislation in July, requiring councils to plan at least 30 years ahead for their highest-risk communities, the Insurance Council of New Zealand welcomed it but said "the proof will be in the doing", and that the hard part is moving from planning to funded delivery. The Council has separately proposed replacing the Fire and Emergency levy on insurance policies with a Community Protection Levy to pay for flood protection and resilience before disasters rather than clean-up after them.

How the cost of adaptation is split between government, councils and homeowners was not settled before the election. It is now a decision for the new government. Until it is made, insurers price renewals in exposed areas on the hazard data they have today.

What is the Reserve Bank looking at?

This year's bank stress test, run jointly by the Reserve Bank and its Australian counterpart, includes a climate sensitivity that tests what happens to the big four banks if premiums rise sharply for the most flood-exposed properties. Results are due in November.

The reason that matters to a homeowner is simple. Your mortgage requires your home to be insured. If cover becomes hard to get in an area, it is not only an insurance problem. It is a lending problem, and the Reserve Bank is testing for exactly that.

What does this mean on the Hibiscus Coast?

We live on a coast. Orewa, Red Beach, Stanmore Bay, parts of Silverdale near the river. Many of the homes we insure are near water, and most of the people who own them have never looked at a hazard map.

Nothing here says the Hibiscus Coast is next. It says the question of insurability is now being asked property by property, using data most homeowners have never seen, and that the funding decision that could change the picture has not been made.

What should a homeowner check now?

Four things, none of which require waiting for the government.

Know your own exposure. Auckland Council publishes flood and coastal hazard information, and a LIM report for your property will show what the council knows. Most people only look at this when buying. It is worth looking at while you own.

Do not let cover lapse. In a hardening market, an existing policy is worth more than a new one. If the Westport decision tells you anything, it is that existing customers were protected and new ones were not. Keep the policy in force and renew on time.

Check your sum insured. Rebuilding costs have moved a long way in five years. If your sum insured has not moved with them, you are carrying a gap that a flood would expose.

Talk to a broker before you buy or sell. If you are looking at a property near water, find out whether cover is available and at what price before you go unconditional. It is a short conversation that can save a very expensive surprise.
