When to review your cover

Insurance is bought at a moment and then left alone. The events that change what you need are predictable, and each one has a short list of things to check.

In short

  • Cover drifts out of line with need within about five years for most households.
  • Every review starts with your existing policies, not with a quote for something new.
  • The most common findings are cover sized to an old mortgage, and a stepped premium heading somewhere unaffordable.
  • Beneficiary nominations after a separation or remarriage are wrong more often than any other detail.
  • Changing jobs usually ends employer group cover, which many people never notice.
  • Reviewing does not mean replacing. Adjusting an existing policy is usually safer and cheaper.

What this is, plainly

A policy is a photograph of your life on the day you bought it. The mortgage was that size, the children were that age, your income was that number, and your health was whatever it was. Everything in that photograph changes, and the policy does not change with it — except for indexation, which quietly increases the sum insured and the premium every year whether or not that matches what you need.

The result is predictable. Households end up over-insured on the thing they bought first and uninsured on the thing that has since become the real exposure. Someone with a $600,000 life policy bought at settlement, a mortgage now down to $250,000, two teenagers and no income protection has their money pointed at the wrong risk.

A review fixes the aim. It does not have to mean buying anything, and a good review quite often concludes that you should change nothing except a beneficiary nomination.

The triggers, and what to check at each

Triggers and checks
What has changedWhat to check
Bought a house or refinancedSum insured against the new loan balance; whether bank-arranged cover was compared; ownership and beneficiary
A baby, or the youngest reaching independenceYears of income to replace; cover on the non-earning parent; whether a special events increase is available without underwriting
Separation or remarriageBeneficiary nominations, policy ownership, relationship property implications, and any court-ordered obligations
Changed jobsWhether employer group cover has ended; whether a continuation option exists; occupation class on income protection
Income changed materiallyIncome protection benefit against current earnings, particularly under indemnity cover
Gone self-employedIncome definition, ACC CoverPlus arrangements, waiting period against your new cash buffer
A health eventDo not cancel anything. Check what you hold and whether a claim or a premium waiver applies
Premium has jumpedStructure, indexation, and whether reducing beats cancelling. Review before you touch the policy
Nothing, but five years have passedEverything above, briefly

A cadence that works

  1. 1Every year, when the renewal notice arrives: check the premium, check whether indexation has increased the sum insured, and decide whether you still want it on.
  2. 2Every two to three years: a proper review of sums insured against current debt, income and dependants.
  3. 3Immediately after any life event in the table above, without waiting for the cycle.
  4. 4Before you cancel or replace anything, always.

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.

  • Indexation increases both cover and premium each year and applies by default at most insurers.
  • Cover bought when you were younger and healthier is often better than anything you could buy now.
  • Special events or future insurability benefits let you increase cover after a life event without new medical evidence — but they have deadlines.
  • Employer group cover is not portable and usually ends with the job, sometimes with a short continuation window.
  • Old policies sometimes have wordings no longer sold, which can be more generous than current products.
  • A review that starts with a quote for a replacement policy is a sales appointment, not a review.

Where an adviser makes a difference

Every New Zealand insurer writes the complete guide to life insurance in nz 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 can compare your existing wording against current market wordings, which a comparison site cannot do.
  • They will spot a special events benefit you can use before its deadline passes.
  • They can restructure — reduce, split, change premium structure — without the risk of re-underwriting.
  • They keep a record of the reasoning, which matters if the advice is ever questioned.

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

How often should life insurance be reviewed?

Briefly every year when the renewal notice arrives, properly every two to three years, and immediately after any material life event — a house, a baby, a separation, a job change or a significant change in income.

What life events should trigger an insurance review?

Buying or refinancing a house, a birth, a child becoming independent, separation or remarriage, changing jobs, going self-employed, a material change in income, and any diagnosis. Each has a specific short list of things to check.

Does my cover automatically increase over time?

If indexation is switched on, yes — most insurers increase the sum insured with CPI each year unless you decline, and the premium rises with it. That is useful protection against inflation but it is not the same as matching your actual need.

Should I review my cover if my premium suddenly jumped?

Yes, and before you do anything else. A jump usually means a stepped premium accelerating, an indexation increase, or a class repricing. Reducing the sum insured or declining the next indexation often solves it without giving up the policy.

Can I increase my cover without being underwritten again?

Sometimes. Many policies include a special events or future insurability benefit allowing an increase after a defined life event — a birth, a mortgage, a marriage — without new medical evidence. These have dollar limits and time deadlines, so use them promptly.
