Cost and cover amounts
Life insurance cost in your 40s
This is peak buying age — peak mortgage, peak dependants, peak income. It is also the decade in which stepped premiums are still cheap enough to look like the obvious choice, and are not.

In short
- By 40 the premium on the same cover is meaningfully higher, and the gap between insurers is wider.
- Between 40 and 45 the cost of identical cover rises steeply — the age curve is not a straight line.
- The mortgage is usually at or near its peak, and the children are expensive but not yet independent.
- Stepped premiums still look affordable at this age, which is exactly why people choose them and regret it at 60.
- Health histories start appearing in this decade, and they are cheaper to underwrite now than later.
- This is the last decade in which level premiums are comfortably affordable for most households.
Want this looked at for your own situation? It is one short form.
StartWhat this is, plainly
The forties are when the numbers get serious in both directions. Household income is usually at its highest, and so is everything the household owes — a mortgage topped up for a renovation, children in the years where they cost the most, and often one partner on reduced hours.
It is also the decade in which insurance stops being cheap enough to ignore. Between 40 and 45 the premium for the same cover rises sharply. Age is priced on a curve, and the curve steepens.
The trap is that stepped premiums at 42 still feel affordable, so people take them, and the annual increases feel small enough to absorb each year. The increases are not small; they are compounding. The consequence lands in the sixties, when a large stepped premium arrives at exactly the point when the claim is most likely and the household income is falling.
What it costs at 40 and 45
| What moves the price | How much it moves it |
|---|---|
| Your age | The biggest lever, and it compounds. The jump from 50 to 60 costs far more than the jump from 30 to 40. |
| How much cover you buy | Roughly proportional. Halving the sum insured roughly halves the premium — this is where real savings come from. |
| Whether you smoke | Smoker rates typically run two to three times non-smoker rates. Most insurers will re-rate you after twelve months smoke-free, if you ask. |
| Stepped or level premiums | Stepped starts cheaper and rises every year. Level starts dearer and holds. Which wins depends on how long you keep the policy. |
| Your occupation | Decisive for income protection and TPD, minor for life cover. Insurers do not all class the same job the same way. |
| Your health history | Settled at underwriting, not at quote. This is what turns an online estimate into a different number. |
Indicative only. New Zealand insurers price per applicant and do not publish comparable tables, so the useful thing to understand is what drives the figure. Cover starts from about $15 a month, and the same cover can cost close to 40% more with one insurer than another.
Two things are worth reading out of that pair. The first is the size of the five-year jump. The second is that the ordering changes — the insurer that is second-cheapest at 40 is not second-cheapest at 45. Rate tables are not parallel lines, which is why re-quoting matters more than loyalty.
The structure decision, made properly
At this age the stepped-versus-level question stops being academic. If you expect to hold cover to 65 or beyond — and most people with a mortgage and teenagers do — the total cost under stepped will exceed level well before you stop paying.
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 your sum insured still matches a mortgage that has been topped up since the policy started.
- Whether a health issue that has appeared in the last few years affects your ability to increase cover.
- Whether indexation has been quietly increasing your premium each year — and whether you want it to continue.
- Whether your income protection benefit still matches your current income, which has probably risen.
Methodology — what these figures include and exclude
Every premium figure on this page is a published market example, not a quote we have generated. Here is exactly what they are.
- There is no neutral published table that ranks New Zealand life insurers on price. Insurers do not release comparable rate cards, and the order changes with age, smoking status, occupation and health history. The only figure that means anything is the one your own application produces.
- New Zealand insurers do not publish rate cards you can lay side by side, so no public table ranks them honestly on price. Which insurer is cheapest moves with age, smoking status, occupation and — most of all — health history. Your own application is the only thing that settles it.
- Both exclude every discount — healthy-lifestyle, membership, multi-benefit and first-year — and both assume a clean health history with no loading applied.
- Neither reflects policy fee treatment, CPI indexation or the cost of riders, and published rates change between updates.
Your own number comes from an insurer in writing, after underwriting. Treat these figures as the shape of the market rather than as your price.

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.
- This is the age at which switching insurers gets risky, because a health history acquired since your original application can be excluded or loaded on a new policy.
- An adviser can compare the cost of keeping an old policy against replacing it, including what you would lose in the switch.
- Converting part of an existing stepped policy to level is possible with some insurers and age-limited with most.
- Rate table ordering changes with age, so the insurer that was cheapest when you bought at 32 may not be now.
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.

Frequently asked questions
How much is life insurance for a 40-year-old in New Zealand?
No New Zealand comparison table settles this. Insurers do not publish rate cards on a common basis, and the cheapest insurer changes with age, smoking status and health history — which is exactly why the market is worth quoting properly rather than read off a page.
How much does life insurance go up between 40 and 45?
On the published figures, materially. The premium for identical cover rises steeply between 40 and 45 — far more than the five years of age would suggest. That is the age curve accelerating.
Is 45 too late to switch to level premiums?
No, but it is more expensive than it would have been at 35, because the level premium is calculated at your current age. It is still usually the better long-run decision if you expect to hold cover past 60. Ask for the cumulative comparison rather than the annual one.
Should I keep my old life insurance policy or replace it?
Be careful. An older policy was underwritten on your health at the time, and anything that has developed since is assessed afresh on a new application — which can mean new exclusions or a loading. Compare wordings, not just premiums.
Do I still need as much life cover in my 40s?
Usually yes, and often more than you had. The mortgage may be lower but the children are more expensive, and income has risen. The reduction typically comes in the following decade, not this one.
