Cost and cover amounts

Premium structures compared

Stepped and level are two ways of paying for the same promise. The difference is when you pay, and over a policy held into your sixties that choice is worth more than the difference between insurers.

In short

  • Stepped premiums are recalculated against your age each year, typically rising between 2% and 15%.
  • Level premiums are fixed to a chosen expiry age — commonly 65, 70 or 80 — and cost more at the start.
  • The crossover typically lands 10 to 15 years in, and arrives sooner the faster stepped rates actually rise.
  • Neither structure protects you from an insurer repricing a whole class of policies.
  • Most cover is yearly renewable to a maximum age, not a fixed-term contract.
  • Whole of life includes an investment element and buys far less cover per dollar of premium.

What this is, plainly

Every life insurance premium is an answer to the same question: what does it cost to insure this person for the next twelve months? Under stepped premiums you pay that figure each year, so it starts low and climbs. Under level premiums the insurer averages the cost across the whole period to a chosen expiry age and charges the average every year.

Neither is inherently better value. Stepped defers the cost, which suits a short need or a tight budget now. Level front-loads it, which suits a long need and protects you from the point at which premiums become unaffordable.

The failure mode of stepped is well documented in this market. People take it out in their thirties, hold it happily for twenty years, and cancel in their late fifties when it starts to bite — losing the cover at the age when a claim is most likely.

The four structures, and what each is for

The structures available in New Zealand
StructureHow the premium behavesBest suited to
SteppedRecalculated against your age each year, typically rising 2–15%Cover needed for ten years or less, or where budget is tight now
LevelFixed to a chosen expiry age, higher at the start, much lower laterCover you expect to hold past your mid-fifties
Yearly renewable termThe default structure in New Zealand — renewable to a maximum age, repriced annuallyAlmost all NZ term cover; it is what “stepped” usually sits inside
Whole of lifeIncludes an investment element and a guarantee of eventual paymentRare in New Zealand; buys much less cover per dollar of premium
Stepped vs level over thirty years, modelled
AgeStepped premium (modelled at 3% a year)Level premium (fixed)Level saves
35$400$800–$400
45$540$800–$260
55$725$800–$75
65$970$800+$170

Illustrative only, based on a $400 starting stepped premium and an $800 level premium held to age 65, modelled at a conservative 3% a year. At a more realistic 8% the crossover arrives roughly a decade earlier. Not a quote.

That model uses 3% a year, which is the conservative end. New Zealand stepped increases commonly run higher, and every extra percentage point pulls the crossover forward. Ask for cumulative cost at 3% and at 8%, run to the age you actually expect to hold the cover — not the annual figure, and not a comparison that stops at 55 where stepped still looks good.

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.

  • The growth rate used in any stepped illustration you are shown, and whether it is realistic.
  • What happens at a level policy’s expiry age — some end, some convert to stepped at your attained age.
  • Whether the insurer can reprice a class of policies, and on what notice.
  • Whether indexation is switched on in the model, since CPI increases apply to both structures and compound.
  • Whether you can convert from stepped to level later, and whether an age limit applies.
  • Whether the comparison runs to the age you will really hold cover, or stops early.

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.

  • Stepped rate tables differ between insurers, so the crossover point is insurer-specific rather than universal.
  • Conversion rights from stepped to level are not standard and usually carry an age limit.
  • Splitting cover across structures inside one policy often beats choosing one, and it is not something people arrange for themselves.
  • Where affordability is genuinely tight, a smaller level sum insured usually beats a larger stepped one that gets cancelled at 58.

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

Which premium structure works out cheaper over a whole policy?

It depends on how long you hold it. Stepped is cheaper for the first decade or so and considerably more expensive later; level is the reverse. Over a policy held fifteen years or more, level usually wins in total, and the faster stepped rates rise the sooner that happens.

When does level premium cover become cheaper overall?

Typically 10 to 15 years in, depending on your age at issue and how fast stepped rates actually rise. Modelled at 3% a year the crossover is late; modelled at a more realistic 8% it arrives materially sooner. Ask for both.

What is yearly renewable term insurance in New Zealand?

The dominant structure here: cover that renews each year to a maximum age, with the premium recalculated at each renewal. Unlike a fixed 20-year contract, cover does not end at a set term — the insurer keeps renewing regardless of health changes, but the price moves.

Is whole of life insurance worth it in New Zealand?

Rarely, for most households. Whole of life includes an investment element and a guarantee of eventual payment, both of which you pay for, so the sum insured you can buy per dollar of premium is much smaller. Term cover plus separate investment usually gives a better outcome.

Can I have part of my cover level and part stepped?

With several insurers, yes. A common structure is level cover sized to long-term needs plus stepped cover sized to a mortgage that will be repaid, so the stepped portion falls away before it becomes expensive.
