Cost and cover amounts

Why your premium went up

There are four reasons a life insurance premium increases, and your renewal notice usually tells you which one applies. Three of them are predictable. One of them is not.

In short

  • Age-related stepped increases: the premium is recalculated each year against your age.
  • CPI indexation: your sum insured rises with inflation, and the premium follows — usually applied by default unless you decline it.
  • Insurer repricing of a whole class of policies, which can affect level premiums too.
  • The end of a first-year or introductory discount, which makes year two look like an increase.
  • Stepped increases typically run between 2% and 15% a year, driven mostly by age.
  • Your renewal notice should show the old and new sum insured — that is how you tell indexation from repricing.

What this is, plainly

Almost every increase falls into one of four categories, and the difference matters because your options are different in each case.

The most common is simply age. If your policy is on stepped premiums, the insurer recalculates the price each year against your current age. In New Zealand those increases typically run somewhere between 2% and 15% a year, and they accelerate as you get older — the rise you absorbed at 35 is applied to a much larger base at 58.

The second most common is indexation, and it is the one people most often do not realise they agreed to. Many policies increase the sum insured each year in line with inflation unless you decline, and the premium rises to match. Your cover grew; you were just not paying attention when it did.

The one that surprises people: repricing

Insurers generally reserve the right to reprice a whole class of policies, and that right usually applies to level premiums as well as stepped. Level removes the age-related component; it does not guarantee the rate table stays where it is. If you are told your level premium has increased, ask to see the clause in the wording that permits it, and ask what notice was required.

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.

  • Whether the increase came with a sum insured increase — that single comparison identifies indexation immediately.
  • Whether a first-year discount has ended, which is common and often not flagged clearly.
  • Whether indexation on a level policy is being priced at your attained age.
  • Whether the insurer has given the notice its own wording requires for a repricing.
  • Whether you are still paying for riders or benefits you no longer need.
  • Whether cancelling in response to an increase would leave you unable to replace the cover.

Where an adviser makes a difference

Every New Zealand insurer writes what life insurance costs 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.

  • The wording that permits an insurer to reprice a class differs, and knowing what yours says is the difference between accepting an increase and questioning it.
  • Where an increase makes cover unaffordable, an adviser can model reducing the sum insured, dropping riders or changing structure before you cancel anything.
  • If your health has not changed, the market may be cheaper. If it has, staying put is usually right — and an adviser will tell you which situation you are in.
  • Indexation can usually be declined for one year or switched off entirely, and the consequences differ.

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.

    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.

    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

Why has my life insurance gone up when nothing has changed?

Most likely your policy is on stepped premiums, which are recalculated against your age every year. Check whether the sum insured also changed — if it did, CPI indexation was applied as well, which means part of the increase bought you more cover.

Can my insurer increase a level premium?

Usually yes. Level removes the age-related increase to your chosen expiry age, but most wordings allow the insurer to reprice a whole class of policies, and indexation still applies unless you decline it. Ask to see the specific clause.

Why did my sum insured go up when I never asked for more cover?

That is CPI indexation, applied by default on many New Zealand policies unless you decline the offer each year. Your cover rises with inflation and the premium rises to match. It stops the cover shrinking in real terms, and it compounds.

Should I turn off indexation to save money?

It is a legitimate lever, but understand the trade-off: your cover stops keeping pace with inflation, and on some policies declining it repeatedly means you lose the right to increase later without new underwriting. Decide it deliberately rather than by inertia.

My premium doubled in year two — is that normal?

It usually means a first-year or introductory discount ended. Ask the insurer for the ongoing premium schedule, not just this year’s figure, so you can see what the cover actually costs over time.
