Cost and cover amounts
How much cover can you actually get
Your needs analysis produces a number. Financial underwriting decides whether an insurer will write it. Above a certain point, the second one wins.

In short
- Insurers cap the sum insured they will write, generally as a multiple of your income.
- The multiple is more generous at younger ages, because there is more future income to protect, and tightens near retirement.
- Above a threshold you will be asked for payslips, tax returns, or an accountant’s letter.
- Non-earners can usually be covered, often to a limit linked to the working partner’s sum insured.
- Business cover is justified against the business rather than against your salary.
- Where one insurer will not write the full amount, splitting across two is normal.
What this is, plainly
Financial underwriting exists for a simple reason. Insurance is meant to restore a loss, not to create a windfall, and a policy worth far more than the financial loss it covers creates an incentive nobody wants to design into a contract. So insurers set limits on how much they will write relative to what you actually earn or owe.
In practice the limit is expressed as a multiple of income. The multiple is larger when you are young, because a 30-year-old has thirty-five years of earnings ahead and a 58-year-old has seven. It is insurer-specific, it changes, and no honest site will quote you a universal figure as though it were a rule.
The limits are rarely a problem for ordinary household cover. They start to bite when the sum insured runs well into seven figures, when income is variable, or when the cover is being taken for a purpose the insurer cannot see on a payslip.
How the limit is worked out
| Who you are | What the limit is based on | What evidence is usually wanted |
|---|---|---|
| Salaried employee | A multiple of gross income, larger at younger ages | Payslips, or an employment letter |
| Self-employed | Income after allowable business expenses, often averaged over one to three years | Tax returns or an accountant’s letter |
| Company shareholder | Salary plus your share of retained profit, or the value of the shareholding | Financial statements, shareholding records |
| Non-earning partner | Usually a limit linked to the working partner’s sum insured | Details of the partner’s cover |
| Business cover | The value of the obligation — loan, shareholding, key person contribution | Loan documents, buy-sell agreement, financials |
If the limit is below what you need
- 1Ask what evidence would support a higher figure. Income that includes bonuses, dividends or retained profit is often understated on a first pass.
- 2Ask whether the purpose changes the assessment. Cover backing a specific debt or agreement is justified differently from general family cover.
- 3Ask whether another insurer would take the full amount. Limits are not standard across the market.
- 4Consider splitting the cover across two insurers, which is a normal arrangement rather than a workaround.
- 5If none of that closes the gap, insure what you can now and use a future insurability benefit to increase later.
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 variable income — commission, bonuses, dividends — has been counted, and how it is averaged.
- Whether a recent income increase is supported by evidence, since insurers usually want more than a verbal figure.
- Whether the maximum for TPD or trauma is lower than for life cover, which it often is.
- Whether cover you already hold with other insurers counts against the limit, which it generally does.
- Whether the evidence requested is proportionate, and what happens to it after the application.
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.
- Financial underwriting limits are not published, and knowing where each insurer sits saves a declined or reduced application.
- Presenting self-employed income properly — which years, which add-backs — can change the maximum materially.
- An adviser knows when to approach a second insurer rather than push a first one past its appetite.
- Where a limit falls short, structuring the shortfall as a future increase under a special events benefit keeps the door open.
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.

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
Is there a limit on how much life insurance I can have in New Zealand?
Yes. Every insurer applies financial underwriting limits, generally expressed as a multiple of income that is more generous when you are young and tightens as you approach retirement. The exact multiples are insurer-specific and are not published.
What evidence do insurers want for a large sum insured?
Payslips or an employment letter for salaried applicants, and tax returns or an accountant’s letter for the self-employed. For business cover, expect to provide loan documents, financial statements or the buy-sell agreement the cover supports.
Does cover I already have count against the limit?
Generally yes. Insurers ask about existing cover and count it towards your total, including policies with other insurers. Non-disclosure of existing cover is a serious problem at claim time, so answer that question fully.
Can I get life insurance if I do not earn an income?
Usually yes. Insurers write cover on non-earning partners, typically to a maximum linked to the working partner’s sum insured. The justification is the replacement cost of the work being done, which is real even though it is unpaid.
What if one insurer will not write the amount I need?
Ask another, and consider splitting the cover between two. Limits and appetites differ across the market, and layering large cover across two insurers is a routine arrangement rather than a sign that something is wrong.
