Life stages
Life insurance for couples without children
Without dependants, the case for a large life sum insured is weaker than the industry suggests. The case for protecting your two incomes against illness is stronger than most couples realise.

In short
- The question is not who would grieve. It is who would be financially worse off, and by how much.
- A joint mortgage is the usual answer. One income cannot always service a loan built for two.
- Illness and injury are far more likely than death at this stage, which puts income protection at the top of the list.
- Trauma cover buys recovery time without either of you having to keep working through treatment.
- If you own a home as joint tenants, the property passes to the survivor — but the debt goes with it.
- Buying young locks in your health. Cover taken at 30 is priced and underwritten on a 30-year-old.
What this is, plainly
Couples without children get sold the same products as couples with them, sized the same way, and it usually does not fit. Life insurance exists to replace what your death would take away from someone else. If nobody depends on your income, the honest sum insured may be much smaller than a standard needs calculator produces — enough to clear joint debt and cover final expenses, rather than a multiple of your salary.
That is not the same as needing nothing. The joint mortgage is the pressure point. Two incomes were used to qualify for the loan, and a lender does not reduce the balance because one borrower has died. The survivor either services the whole thing alone, refinances, or sells the house in the worst year of their life. Cover sized to the debt, on each life, removes that choice from the equation.
The bigger exposure, though, is illness. In your thirties and forties you are far more likely to be off work for months than to die, and a household running two incomes and a matching mortgage has little slack. Income protection and trauma cover are what answer that, and they are the products couples without children most often skip.
Sizing it properly
- 1Work out what the survivor’s position would be on one income: mortgage, rates, insurance, running costs.
- 2Cover the gap, not your salary. If one income comfortably services the loan, you may need far less life cover than you think.
- 3Then insure the incomes. Income protection for both, with waiting periods matched to your savings.
- 4Add trauma cover sized to a year of household costs, so a diagnosis does not mean working through treatment.
- 5Revisit the whole plan if children, a business or a dependent parent enter the picture — the answer changes completely.
The argument for buying young anyway
There is one good reason to hold life cover before you need it: insurability. Premiums are set by age and health at the time you apply, and a policy taken out at 30 keeps that underwriting for as long as you hold it. A diagnosis at 38 does not change the terms of cover you already own — but it can make new cover expensive or unobtainable. If children are likely, a modest policy now is cheap optionality.
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 you hold the house as joint tenants or tenants in common — it decides whether the property passes automatically to the survivor.
- Whether the mortgage is serviceable on one income at current rates, not at the rate you fixed at.
- Whether either of you has a student loan, a personal guarantee on a business loan, or a family loan.
- Whether employer-provided cover exists, what it covers, and that it ends when the job does.
- Whether income protection is agreed value or indemnity if one of you is self-employed or on variable pay.
- A special events benefit, so you can increase cover if a child arrives without new health questions.
Where an adviser makes a difference
Every New Zealand insurer writes cover for a two-income household 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.
- Being willing to recommend less cover than a calculator suggests, and documenting why.
- Sizing life cover against a real one-income budget rather than a salary multiple.
- Comparing income protection wordings, where the differences between insurers are much larger than the price differences.
- Setting the plan up so it can scale if your circumstances change, rather than needing to be rebuilt.
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
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
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
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
Do we need life insurance if we have no children?
Only to the extent someone would be financially worse off. A joint mortgage is usually reason enough. If you rent, have no shared debt and both have savings, the honest answer may be that you need income protection and very little life cover.
What happens to our mortgage if one of us dies?
The debt does not die with the borrower. If you own the property as joint tenants it passes to the survivor, complete with the loan, and the bank expects the payments to continue. The estate may repay some of it, but the survivor is generally left servicing a loan that two incomes qualified for.
Is income protection more important than life cover for us?
For most couples in this position, yes. You are far more likely to lose an income to illness or injury than to death, and the financial consequence of a six-month absence with a two-income mortgage is immediate. Life cover matters, but usually at a smaller size.
Should we get a joint policy since it is just the two of us?
A joint policy is cheaper and pays once, which leaves the survivor uninsured at an older age. Two single policies cost more, pay independently, and stay yours if the relationship ends. For most couples the second structure is worth the difference.
We do not want children — does that change the advice permanently?
It changes the size, not the principle. Debt, a business, a dependent sibling or parent, or a partner who could not manage the house alone are all reasons cover still makes sense. Review it when circumstances change rather than deciding once and forgetting.
Is it worth buying life cover now in case we need it later?
It can be. Cover is priced on the age and health you have when you apply, and holding a modest policy preserves that. If there is any chance of children or a larger mortgage in the next decade, a small policy with a special events benefit is inexpensive insurance against becoming uninsurable.
