Replacing a Life Insurance Policy in NZ (2026): When Switching Insurers Helps and When It Backfires

A cheaper quote isn't always a better deal. Here is what you can lose when you replace a life, trauma or income-protection policy in NZ — reset stand-downs, fresh underwriting, narrower definitions — and the FMA replacement rules an adviser must follow.

This article is general information only and is not personalised financial advice. It does not take into account your particular financial situation, goals or needs. Before acting, consider whether it's right for you and seek advice tailored to your circumstances.

A cheaper quote arrives, or someone offers to "shop the market" and save you money. Replacing a life insurance policy can be the right call — but it is one of the few insurance decisions where doing it badly can cost you far more than you save. When you switch insurers, the new policy is written from scratch: re-underwritten at your current age and health, with fresh stand-down periods and, often, different definitions. This guide explains when replacing genuinely helps, when it backfires, and how to switch without losing cover you can't get back.

TL;DR: The FMA treats replacing a life policy as a high-risk transaction, because claims can be declined later and original benefits lost — and you may not find out until you try to claim ¹. Switching can make sense, but the new policy is re-underwritten and stand-downs reset. The golden rule: never cancel the old cover until the new one is confirmed in force.

Why isn't a cheaper quote always a better deal?

Premium is the easiest number to compare and the one that tells you least about whether a claim will be paid. A lower price usually reflects a narrower contract — a tighter definition, a new exclusion, or an option dropped — not pure generosity from the insurer.

This is the FMA's core concern, and it is not a small one. Most "new" life insurance written in New Zealand is actually replacement business — people switching providers rather than buying cover for the first time ². When the regulator reviewed 11 firms, fewer than half were advising customers that replacing their cover could lead to worse cover or the loss of benefits; only two firms had high-quality processes built around customer outcomes, six needed improvement, and three may not have been meeting their legal obligations ³.

An earlier FMA report on life-insurance sales practices found some advisers replaced more than 35% of their policies in a single year — effectively churning a client's whole book every three years — and flagged roughly 200 advisers doing about $110 million in annual premium as high-churn, out of the $1.7 billion New Zealanders spent on life premiums in the year to 30 June 2014 ⁵. The lesson for consumers is not that switching is bad, but that a cheaper premium on its own is a weak reason to move.

What can you lose by replacing a policy?

The risk with replacement is that the things worth keeping are invisible on a price comparison. Older, in-force policies often carry more favourable terms and broader benefit definitions than newly issued contracts — for example, wider trauma or critical-illness definitions — so moving to a cheaper premium can quietly mean a narrower definition and a higher chance of a future claim being declined ⁹.

The things most commonly lost on replacement:

• Broader definitions. A trauma definition written years ago may pay on a wider range of events than today's equivalent. Two policies both called "trauma cover" can decide a heart-attack claim completely differently.
• Clean terms — no exclusions or loadings. If your old policy was issued before a health condition appeared, it may have no exclusion or premium loading for it. A new policy will be underwritten on your health today.
• Grandfathered benefits. Some older contracts include features or guarantees the insurer no longer offers to new customers.
• Continuous cover. Time already served on the old policy — including any stand-down periods you have already cleared — does not carry across.

Whether any of these matter depends entirely on your situation. Someone in good health who took out a basic policy last year has little to lose; someone with a ten-year-old policy and a health change since has a great deal to lose. That is the assessment that has to happen before anyone cancels anything.

How do new stand-downs and re-underwriting work on replacement?

Two mechanical things happen when you take out a replacement policy, and both can work against you.

First, the new policy is re-underwritten at your current age and health ⁶. Any condition you have developed since the original policy was issued — a back problem, raised blood pressure, a mental-health history, anything disclosed to a GP — can now attract a new exclusion or a premium loading that the old cover never carried. The old policy is sometimes worth keeping precisely because it was underwritten when you were younger and healthier.

Second, benefit-specific stand-down (waiting) periods reset. Trauma or critical-illness cover and income protection commonly carry stand-downs that start again on a new policy ⁷. So a claim that would have been payable under your old cover may not be payable under the new one for an initial period after it starts. If you replace cover and a claim arises inside that window, you can fall into a gap that neither policy fills.

Whether a claim is paid depends on the terms, conditions, exclusions, stand-down periods and underwriting of the specific policy, and on your disclosure. Always read the policy wording.

The golden rule: never cancel before the new cover is in force

This is the single most important point in the article, and it is simple. Do not cancel, reduce or lapse your existing policy until the replacement is confirmed accepted and in force in writing — with the final terms, any exclusions, any loadings, and the start date all known.

The reason is that an application is not cover. Between applying and being accepted, the new insurer may apply an exclusion, add a loading, or decline you outright based on what the underwriting turns up. If you have already cancelled the old policy, you can be left with no cover at all, or stuck with worse terms than you started with — and at that point you may not be able to go back. Running the old and new cover in parallel for a short overlap costs a little extra premium for a few weeks. It is cheap insurance against being uninsured.

When does replacing a policy genuinely make sense?

Replacement is a tool, not a trap. There are sound reasons to move, and an adviser's job is to weigh them honestly against what you would give up. Replacing can make sense when:

• Your cover no longer matches your needs — for example you need a benefit type your current insurer doesn't offer, or your existing policy has a structural limitation a newer contract solves.
• The new policy is clearly broader, not just cheaper — better definitions, fewer exclusions, or features the old one lacks, confirmed by reading both wordings.
• Your current insurer's financial strength or service has materially weakened, and a stronger insurer can offer comparable or better terms.
• You are in good health and the old policy was never great — if there is little to lose on underwriting and the new terms are genuinely better, the maths can favour switching.
• You're consolidating several small or overlapping policies into a cleaner, better-structured arrangement.

The common thread is that the decision rests on the quality of the cover, with price as one input among several — not the headline premium alone. If the only reason to move is a slightly lower price, that is usually a signal to look harder at what is being traded away.

What does the FMA expect from replacement advice?

Because replacement is high-risk for consumers, the regulator expects advisers to demonstrate that a switch is in the client's interests — not the firm's. When the FMA reviewed replacement business, it found firms' processes were generally oriented toward reducing the firm's own legal risk rather than identifying and mitigating risks for the customer, with replacement "forms" used as a risk-management tool presented at the end of the advice process rather than to genuinely help customers decide ⁴.

That scrutiny is ongoing. As at early 2025 the FMA was scoping a second review of financial-advice business and remuneration models, to identify structures that pose higher consumer risk — a clear signal that advisers are expected to show, on the file, why a replacement benefits the client ⁸. In practice, the standard means an adviser should compare the old and new cover properly, spell out in writing what you may lose as well as gain, and only recommend replacing where the case genuinely stacks up for you.

How does an adviser run a safe replacement comparison?

A safe replacement is a process, not a quote. The checklist below is the framework an adviser works through before recommending you move — and the same questions are worth asking whoever proposes a switch.

The point of running it this way is that the decision is made on evidence, in writing, before anything is cancelled. If you want the background on reading your existing cover first, see our guide on reviewing an old life insurance policy. For how advisers weigh wordings and insurer strength rather than price alone, see how advisers compare insurers in NZ. And because premium structure often comes up in a switch, level vs stepped premiums is worth a read.

We work with a panel of selected insurers, listed in our disclosure — we don't search every provider in the market, and a replacement is only recommended where it is genuinely in your interests. We're generally paid by commission from the insurer when you take out a policy through us; this doesn't change the premium you pay, and we manage any conflicts of interest in line with our duty to prioritise your interests. Full details are in our Disclosure.

Frequently asked questions

Is it bad to switch life insurance in New Zealand?

Not necessarily — but the FMA treats replacing a life policy as a high-risk transaction because benefits can be lost and claims declined later, sometimes without the customer realising until they claim ¹. Switching can be the right move where the new cover is genuinely better, not just cheaper. The risk is switching on price alone and quietly accepting narrower terms or fresh exclusions.

Will I have to answer health questions again if I replace my policy?

Yes. A replacement policy is re-underwritten at your current age and health, so any conditions you've developed since the original policy was issued can attract new exclusions or premium loadings the old cover didn't carry ⁶. This is a key reason an older policy can be worth keeping.

Do stand-down periods start again on a new policy?

Generally yes. Benefit-specific stand-downs — common on trauma, critical-illness and income protection — start again on a new policy, so a claim payable under your old cover may not be payable under the new one for an initial period ⁷. Keeping the old policy in force until the new one starts avoids a gap.

Should I cancel my old policy as soon as I apply for a new one?

No. An application is not cover. Wait until the replacement is confirmed accepted and in force in writing — with final terms, exclusions, loadings and start date all known — before cancelling anything. Otherwise an exclusion, loading or decline on the new policy could leave you with no cover.

How do I know if my old policy has terms worth keeping?

Older in-force policies often have broader benefit definitions and may have been underwritten before a health condition appeared, meaning clean terms a new policy won't replicate ⁹. The only way to know is to read both wordings side by side. That comparison is exactly what a replacement review is for.

Does replacing cover cost me a fee with an adviser?

There's usually no direct charge to you — we're typically paid a commission by the insurer when a policy is taken out, which doesn't change your premium. We manage any conflicts in line with our duty to put your interests first, and full details are in our Disclosure.
