Mortgage Repayment Cover vs Income Protection in NZ (2026): The Difference That Matters at Claim Time

The bank's mortgage repayment cover protects the loan. Full income protection protects your income. Here is how they differ on benefit basis, ownership and portability — and why it matters when you claim.

When you draw down a home loan, the bank often offers a "mortgage repayment cover" alongside it. It sounds like income protection, and it does sit in the same family. But the two are not the same product, and the gap between them shows up at exactly the wrong moment — when you are off work and a claim is being assessed.

This guide explains what mortgage repayment cover actually does, how it differs from full income protection, and how to think about which one (or both) fits a household with a mortgage.

TL;DR: Mortgage repayment cover pays toward your mortgage or rent only — often up to around 115% of repayments or 45% of gross income ³. Full income protection replaces up to about 75% of your income ¹, covering the whole household budget. The bank's version protects the loan; income protection protects you.

What is mortgage repayment cover and how does it work?

Mortgage repayment cover is a narrower form of income protection. If illness or injury stops you working, it pays a monthly benefit aimed at covering your home loan repayments (and often rent, if you are renting) until you can work again or the benefit period ends ³.

The benefit is usually sized to your repayments rather than your whole income. As one example, AIA's mortgage repayment option insures up to 115% of your mortgage or rent repayments, or 45% of your gross income, whichever applies under the policy ³. The slightly-over-100% allowance is designed to cover associated costs like rates or insurance, not to replace your wider income.

Like full income protection, it generally pays for illness as well as injury — which is the main reason people hold it. ACC covers accidents and injury, but not illnesses such as cancer, heart disease, stroke or most mental-health conditions ⁴. A policy that pays on illness fills that gap.

It is regulated as an insurance contract under the conduct and disclosure regime the Financial Markets Authority oversees, so the policy document (PDS) is where the real terms live — cover, benefit basis, waiting and benefit periods, and any offset clauses ⁷.

How is it different from full income protection?

The simplest way to see the difference is what each one is trying to replace.

• Mortgage repayment cover replaces a slice of your outgoings — the mortgage or rent. If your repayments are $2,800 a month, that is roughly the size of the benefit, subject to the policy caps ³.
• Full income protection replaces a slice of your income. Most NZ insurers let you cover up to about 75% of your pre-disability income as a monthly benefit ¹.

Many insurers also tier the income-replacement percentage by income band — commonly around 62.5% on income up to $70,000, 60% from $70,001 to $100,000, and 55% above $100,001 — so the headline figure isn't universal at higher incomes ². The benefit is typically a taxable monthly amount, and maximum monthly benefits commonly sit in the $15,000–$30,000 range depending on the insurer ².

The figure below sets the two side by side.

The pattern is consistent: mortgage repayment cover is cheaper because it insures less. That is not a flaw — for some households it is exactly the right minimum. It just isn't the same thing as protecting your income.

Why the bank's version may only cover the mortgage, not your life

If you are off work for months, the mortgage is only one of the bills. Power, food, rates, school costs, the car, KiwiSaver contributions and everything else keep arriving. Mortgage repayment cover, by design, only addresses the loan ³.

That can be enough if the rest of the budget is covered another way — a working partner, savings, or a separate policy. But "the mortgage is covered" and "the household is covered" are different statements. A benefit sized to your repayments will not stretch to replace your wider income.

This is the trade-off: lower cost and a simpler product, against narrower cover. Neither answer is automatically right — it depends on the household's other income, debts and savings. Our guide on choosing between income protection and mortgage protection for your home works through that decision in more depth.

Is mortgage repayment cover usually indemnity or agreed value?

Mortgage repayment cover is commonly offered on an indemnity basis ³. That means the benefit is assessed against your actual income and repayments at the time you claim, not locked in when you applied.

Full income protection can be either:

• Agreed value — the insured benefit is set and proven when you take out the policy, and paid regardless of what your income looks like later ³.
• Indemnity — the benefit is re-tested against your actual recent income at claim time ³.

Why does this matter? With indemnity cover, if your income has fallen in the period before you claim, the benefit can be re-calculated downward. For someone with steady, easily-proven income that rarely bites. For someone self-employed, seasonal, or with variable earnings, it can. We cover that distinction in detail in our piece on agreed value vs indemnity income protection.

The practical point: don't assume a mortgage repayment policy will simply pay your repayments no questions asked. On an indemnity basis, the insurer can still test your income at claim time. The PDS sets out exactly how ⁷.

What happens to bank-arranged cover if you refinance elsewhere?

This is the difference people most often miss. Bank-arranged mortgage repayment cover is frequently linked to the specific loan and lender ⁸. If you later refinance to another bank for a better rate, the cover may not automatically transfer — and it can lapse ⁸.

A standalone policy held directly with an insurer behaves differently. It is portable: it continues regardless of which bank holds your mortgage, because it covers you, not the loan ⁸.

That has a real consequence. Cover lapsing on refinance is not just an admin gap — if your health has changed since you first took out the policy, a new application could be underwritten less favourably, excluded, or declined. Cover you already hold is generally far easier to keep than cover you have to re-apply for. So before refinancing, it is worth checking whether any loan-linked cover travels with you or stops.

Portability is one of the main reasons some households prefer to hold their protection with an insurer rather than bundle it with the loan.

How do offsets and ACC affect mortgage repayment cover?

Income protection and mortgage repayment cover are generally designed so you don't end up insured for more than your income — over-insurance removes the incentive to return to work, and insurers price and structure cover to avoid it.

Two offsets matter:

• ACC. Where ACC weekly compensation applies, an indemnity policy's benefit is typically offset (reduced) so the combined total doesn't exceed your insured percentage ⁴. ACC weekly compensation pays up to 80% of pre-incapacity income — but only for accidents and injury, not illness ⁴.
• The ACC cap. ACC weekly compensation is capped at a maximum weekly amount, reset each 1 April. For the year from 1 April 2026 the cap is in the order of $2,500-plus per week (confirm the exact indexed figure on the ACC site) ⁵. Income above the cap is not replaced by ACC, which is one of the gaps income protection is built to fill.

So if you are injured, ACC may carry much of the load and your policy offsets around it. If you are unwell rather than injured, ACC generally pays nothing — and the full weight falls on your insurance ⁴. That asymmetry is the core reason illness-and-injury cover exists at all.

When is mortgage repayment cover the right minimum?

There are households for whom mortgage repayment cover is a sensible, affordable floor:

• One income is comfortably covered by a partner, so only the mortgage needs protecting.
• Budget is tight and some protection is far better than none — covering the loan keeps the roof secure.
• The mortgage is the dominant fixed cost and other expenses are modest or flexible.

New residential mortgages in NZ commonly run into the hundreds of thousands of dollars, with first-home-buyer averages often in the mid-to-high $500,000s ⁶. At that size, even just protecting the repayments is meaningful — losing the home is the outcome most people most want to avoid.

The honest framing is "minimum, not maximum." Mortgage repayment cover keeps you in the house. It does not, on its own, keep the wider household budget running. Whether that's enough depends on what else is in place. Our guide on which cover to put first when you take on a new mortgage is a good companion if you are starting from scratch.

Should you have repayment cover, full IP, or both?

There is no single right answer — it depends on income, debts, dependants, savings and what a partner earns. A few questions are usually more useful than a blanket rule:

• Is yours the only income the household relies on? If so, covering only the mortgage may leave a large gap; full income protection covers more of the budget.
• Is the mortgage your main fixed cost, with a second income behind you? Mortgage repayment cover may be a reasonable, lower-cost minimum.
• How stable and provable is your income? On indemnity cover, a recent income drop can reduce the benefit; that's worth weighing when you choose the basis ³.
• Could you refinance in the next few years? If so, portability matters — loan-linked cover may not travel with you ⁸.
• What's the right wait period and benefit period? These shape both cost and how long you're protected; our explainer on wait period vs benefit period covers the trade-offs.

Some households run both — full income protection for the income, with the mortgage simply forming part of what that benefit covers — while others start with repayment cover and build up. The right mix is a conversation, not a default.

Frequently asked questions

What's the difference between mortgage repayment cover and income protection? Mortgage repayment cover pays toward your mortgage or rent repayments only — often up to around 115% of repayments or 45% of gross income ³. Full income protection replaces a percentage of your whole income, up to about 75% ¹. The bank's version protects the loan; income protection protects your wider household budget.

Does mortgage repayment cover pay for illness, or just injury? It generally pays for illness as well as injury, which is its main purpose. ACC covers accidents and injury but not illnesses such as cancer, heart disease, stroke or most mental-health conditions ⁴. Always check the specific policy wording for what is and isn't covered.

Is mortgage repayment cover indemnity or agreed value? It is commonly offered on an indemnity basis, meaning the benefit is assessed against your actual income and repayments at claim time rather than locked in at application ³. Full income protection can be agreed value or indemnity depending on the policy.

If I refinance to another bank, do I keep my mortgage repayment cover? Bank-arranged cover is often linked to the specific loan and lender, so it may not transfer automatically and can lapse if you refinance elsewhere ⁸. A standalone policy held with an insurer is portable and continues regardless of which bank holds the mortgage ⁸.

Does ACC reduce what mortgage repayment cover pays? On an indemnity policy, where ACC weekly compensation applies the benefit is typically offset so the combined total doesn't exceed your insured percentage ⁴. ACC pays up to 80% of pre-incapacity income for injury only, and is capped at a maximum weekly amount reset each 1 April ⁴⁵.

Do I need both repayment cover and full income protection? Not necessarily — it depends on your income, debts, savings and what a partner earns. For some, repayment cover is a sensible minimum; for others, full income protection is a better fit. Personalised advice works through what suits your situation.
