Getting cover

Switching life insurance without losing cover

One rule governs this entire subject: never cancel an existing policy until the replacement has been issued and is in force. Everything else on this page is detail hung off that sentence.

In short

  • Never cancel until the new policy is issued, accepted and confirmed in force in writing.
  • Switching means being re-underwritten at your current age and your current health, not the health you had when you first applied.
  • Loadings and exclusions do not carry over — but neither do the terms you originally earned. Anything new gets assessed fresh.
  • Any condition diagnosed since your original policy can be loaded, excluded or declined on the new one.
  • An adviser recommending replacement carries a documented duty to show why it leaves you better off.
  • Sometimes switching is right — a structure change, a stabilised condition, or a genuinely better wording.

What this is, plainly

Switching insurers is the part of this market where consumer interest and commercial interest are most obviously misaligned. Replacement business pays upfront commission. That does not make every recommendation to switch a bad one, but it does mean you should expect the reasoning in writing and should read it carefully.

The mechanical risk is simple. Your existing policy was underwritten against the person you were when you applied. If you have had anything happen since — a diagnosis, an investigation, a change in build, a medication started — the new insurer assesses all of it. You may be offered the same cover with a loading, with an exclusion, or not at all.

The worst outcome, and it happens, is cancelling the old policy in anticipation and then finding the new one comes back on terms you cannot accept. At that point you have neither. It is entirely avoidable, and avoiding it costs nothing but a few weeks of paying two premiums.

How to switch without leaving a gap

  1. 1Do not touch the existing policy. Not a cancellation, not a payment holiday, not a reduction.
  2. 2Get the new cover quoted and apply, disclosing everything fully, including anything that has changed since your original application.
  3. 3Wait for the insurer’s offer of terms. Read it — the terms offered are not necessarily the terms quoted.
  4. 4Compare the offered terms against your existing policy clause by clause: terminal illness, trauma list, TPD definition, exclusions, loadings, indexation, premium structure.
  5. 5Accept, pay the first premium and get written confirmation that the new policy is in force.
  6. 6Only then cancel the old policy, in writing, with an effective date on or after the new policy’s start date.
  7. 7Keep both confirmations. You want a paper trail showing there was no day on which you were uninsured.

What you lose that is easy to overlook

  • Time already served against any pre-existing condition or suicide clause on the original policy — these usually restart.
  • Trauma stand-down periods, which begin again on the new policy.
  • An older wording that may be more generous than what is currently sold, particularly on trauma condition lists.
  • Any pass-back benefit under which your old insurer applies wording improvements to your existing policy.
  • Continuity of a loading you have already accepted — a new insurer may load you more heavily, or exclude what the old one merely loaded.

When switching genuinely is the right call

  • You need a premium structure change the current insurer will not offer — moving to level, for example, when stepped is becoming unaffordable.
  • A condition that was loaded or excluded years ago has since stabilised, and another insurer will now take it on better terms.
  • Your current insurer’s wording has a specific weakness that matters to you, and a competitor’s is materially better on that point.
  • Your cover was arranged at a mortgage settlement, was never compared, and is priced well above the market for the same terms.
  • Your circumstances have changed enough that the policy no longer fits — new occupation class, self-employment, a much larger sum insured.

Not sure what cover you actually need?

That is the question an adviser is there to answer. Tell us your situation and a licensed New Zealand adviser will compare the market and come back with a written recommendation — including where you can cut cover you do not need.

No cost to you and no obligation. General information only — not personalised financial advice.

What to watch for

These are the details that decide whether the cover does what you expected. Read them before you compare on price.

  • Any recommendation to switch that does not include a written comparison of the old and new wordings.
  • Advice to cancel first “to avoid paying two premiums”. The overlap is the cheapest insurance you will ever buy.
  • New stand-down and pre-existing condition periods restarting on the replacement policy.
  • Whether the new policy is guaranteed renewable, and whether the old one was.
  • First-year discounts that make the replacement look cheaper than it will be in year two.
  • Whether your old policy is one an insurer no longer sells, which sometimes means better terms than anything available now.

Where an adviser makes a difference

Every New Zealand insurer writes life insurance in new zealand to its own wording, and the words are where the money is. Two policies that look identical on price can pay very differently when it matters. Closing that gap is the entire job of an adviser.

  • An adviser recommending replacement is required to document why the switch leaves you better off — hold them to it.
  • They can pre-assess your current health with the new insurer before anything is cancelled.
  • They can sequence the application so the two policies overlap and there is never an uncovered day.
  • They can often improve your existing policy without replacing it, which is the outcome that pays them least and suits you most.

There are three ways to buy life cover in New Zealand, and they are not equivalent. You can buy direct from one insurer, which means you see one product range and one underwriting appetite. You can buy through your bank, which usually means a single insurer’s product sold under the bank’s brand, often with narrower definitions. Or you can go through an adviser, who quotes several insurers at once and is required to put your interests first.

The premium you pay is the same either way. Insurers build adviser commission into their pricing whether or not an adviser is involved, so going direct does not get you a discount — it just removes the person whose job is to argue your corner at application and at claim time.

  • An adviser can see which insurer is currently taking your health history on standard terms, and which one will load or exclude it.
  • An adviser can structure cover across two insurers if that produces a better outcome than putting everything with one.
  • An adviser handles the underwriting back-and-forth, and is the person who chases the claim when a family is least able to.
  • An adviser has to document why the recommendation suits you, which is a written record you can hold them to.

What happens if you get in touch

We are a referral service, not an insurer. We do not quote premiums and we do not sell policies. What we do is put you in front of one licensed New Zealand adviser who can compare the market properly.

  1. 1

    You tell us what you are looking at

    The form takes about a minute. Nobody asks for your medical history on a web form — that conversation happens with the adviser, properly, and only once you have decided to proceed.

  2. 2

    An adviser calls you

    A licensed New Zealand adviser talks through your situation: who depends on you, what you owe, what you already have in place, and what you are actually worried about.

  3. 3

    They compare the market

    The adviser quotes across the major insurers, checks which of them will take your health history on the best terms, and puts the options side by side in writing.

  4. 4

    You decide, in your own time

    There is no obligation and no cost to you. If the answer is that you already have enough cover, a good adviser will tell you that.

Frequently asked questions

Can I switch life insurance companies in New Zealand?

Yes, but it is a new application, not a transfer. The new insurer underwrites you at your current age and health. Nothing carries over — not your original terms, not time served on stand-downs, not an existing loading. Treat it as buying cover from scratch.

Should I cancel my old policy before the new one starts?

Never. Cancel only after the new policy has been issued, accepted and confirmed in force in writing, with an effective date that leaves no gap. Paying two premiums for a few weeks is the cost of not being uninsured at the wrong moment.

Will my exclusions transfer to a new insurer?

No, and that cuts both ways. A new insurer assesses your history fresh, so an old exclusion does not automatically follow you — but nor does the acceptance you originally earned. Anything diagnosed since your first application is now part of the assessment.

Is it worth switching life insurance to save money?

Only if the cover is genuinely equivalent and you are healthy enough to be re-underwritten without new loadings. A cheaper premium on a narrower wording is not a saving. Ask for a clause-by-clause comparison before you look at the price difference.

What is a replacement advice duty?

It is the obligation on an adviser recommending you replace existing cover to establish and document that the replacement is in your interests, including what you lose. If you are being advised to switch, ask for that analysis in writing.

What if my new application is declined after I have applied?

If you followed the rule and kept the old policy in force, nothing happens — you simply stay where you are. This is precisely why the sequencing rule exists, and it is the reason advisers who do this properly never cancel first.
