Income Protection vs Mortgage Repayment Holiday in NZ (2026): The Trap of Relying on Your Bank Instead

A mortgage repayment holiday pauses your payments but not your debt. Here is why a repayment holiday is a deferral rather than income cover, how capitalised interest grows your loan, and how income protection actually replaces income while you recover.

When illness stops your income, the first call many people make is to their bank, hoping a mortgage repayment holiday will get them through. It is a reasonable instinct, and a repayment holiday can genuinely help for a short stretch. The problem is that a repayment holiday and income protection are not the same tool. One pauses your loan payments and quietly adds to your debt; the other replaces a slice of your income so you can keep paying the bills. Relying on the first when you actually need the second is where people get caught.

This guide explains how a repayment holiday works, why it is a deferral rather than cover, how the interest stacks up, and where income protection, ACC and sick leave each fit.

TL;DR: A mortgage repayment holiday pauses repayments but interest keeps accruing and is capitalised onto the loan, so your debt grows ¹. Income protection instead replaces an agreed share of income — commonly up to about 75% — while you cannot work through illness or injury ⁷. A holiday buys weeks; income protection is built for months.

What is a mortgage repayment holiday and how does it work?

A mortgage repayment holiday is an arrangement with your lender to pause or reduce your home loan repayments for an agreed period, usually a few months. It is sometimes called a repayment deferral or a payment pause. The idea is to give a borrower breathing room during a temporary squeeze — a redundancy, a new baby, or time off work through illness or injury.

The mechanics are the important part. During the holiday you either stop making repayments altogether or drop to interest-only. The bank does not write off anything. Interest continues to be charged on the outstanding balance the whole time, and that interest is added to your loan — capitalised — so the amount you owe goes up, not down ¹.

Lenders also treat repayment holidays as a discretionary arrangement, not an automatic right. You generally need to apply, meet the lender's criteria, and the bank decides whether to approve it and for how long. It is worth checking your own lender's current terms rather than assuming a holiday will be available the moment you need one.

Why is a repayment holiday a deferral, not income cover?

This is the distinction that matters most. A repayment holiday does nothing about your income. It only changes the timing of your mortgage payments. Your power bill, rates, groceries, insurance premiums and every other cost carry on exactly as before — and you are meeting them with less money coming in, or none.

Put plainly: a holiday moves a debt around; it does not put money in your account. Income protection does the opposite. It pays you a monthly benefit to partly replace the income you have lost, which you can then use for the mortgage and everything else ⁷. A repayment holiday helps with one line of your budget for a short time. Income cover helps with all of them, for longer.

There is also a structural difference. A repayment holiday is something you ask the bank for after the trouble starts, and the bank can say no. Income protection is a contract you put in place beforehand; provided you have disclosed properly and the claim meets the policy terms, the benefit is payable regardless of what your bank decides ⁷. The two are not competing options so much as different layers — and leaning only on the deferral is the gap most people do not see until they are in it.

How does capitalised interest grow your loan during a holiday?

Because interest keeps running and is added to the balance, a repayment holiday makes your loan bigger and your future repayments higher ¹. The longer the holiday, and the larger the loan, the more this bites.

The scale here is not trivial. Residential mortgage debt in New Zealand reached about NZ$381 billion by the third quarter of 2025, and average new mortgages run into the hundreds of thousands of dollars ⁸. On a loan of that size, several months of capitalised interest is a meaningful sum added to a debt you will be repaying for years.

The pattern is consistent. A holiday lightens one bill briefly while adding to your debt; income protection replaces income across the board while leaving your loan untouched. Our companion piece on mortgage repayment cover versus income protection digs further into how the two are structured.

What happens to your income if illness lasts months, not weeks?

Short illnesses are usually survivable on sick leave and savings. The real risk is the illness or injury that runs for months — a cancer treatment cycle, a serious back problem, a mental health condition, a long recovery from surgery. That is where a repayment holiday runs out of road, because banks grant them for limited periods and the capitalised interest mounts the whole time ¹.

Many household budgets are not built to absorb a long gap. Once sick leave is exhausted and any savings buffer is gone, the income simply is not there, and a paused mortgage does nothing to bring it back. This is the scenario income protection is designed for: a sustained loss of earnings through illness, not just injury. If you are weighing how long your own savings would actually last, our piece on income protection versus a savings buffer walks through that maths.

How does income protection replace income while you recover?

Income protection insurance pays a regular monthly benefit when you cannot work because of a covered total or partial disability, including illness — not only injury. Most NZ policies replace an agreed proportion of your pre-disability income, commonly up to about 75%, with the exact figure and definitions set out in each insurer's product disclosure statement ⁷.

A few features make it suited to the long-haul scenario a holiday cannot cover:

• It is income, not a pause. The benefit is cash you can put toward the mortgage and every other cost, rather than a deferral that grows your loan ⁷.
• It covers illness, which ACC does not. ACC only compensates for accidental injury, so income protection is what fills the much larger illness gap ².
• It runs to a chosen benefit period. You select how long the benefit can pay for — often to age 65 on longer plans — so it is built for months or years, not weeks.

The trade-offs are real and worth stating plainly. Income protection costs a regular premium whether or not you ever claim. Benefits are taxable, generally start only after a chosen wait period, and a claim is paid only where it meets the policy's terms, conditions, exclusions, stand-down periods and underwriting — and where you disclosed your health and circumstances accurately. It also offsets against ACC and other income so the combined total stays within the insured percentage. None of that makes it the wrong tool; it just means the cover has to be set up properly to do its job. The income protection or mortgage protection explainer covers how it sits alongside a home loan specifically.

When is a repayment holiday a sensible short-term tool?

A repayment holiday is not a bad thing — it is just the wrong thing to rely on as your main safety net. Used for what it is, a short bridge, it can be genuinely useful.

It tends to make sense when the gap is clearly temporary and you can see the other side: a few weeks between jobs, a short recovery with a firm return-to-work date, or a stopgap while a claim or other support is being arranged. In those cases the capitalised interest is small relative to the breathing room it buys ¹.

Where it falls short is as a substitute for income when the time off is open-ended. The longer it runs, the more it costs in added debt, and it never addresses the underlying problem, which is that your income has stopped. Treated as one short-term lever among several, a holiday earns its place. Treated as the plan, it leaves the biggest risk uncovered.

How do ACC and sick leave fit before either option?

Before you reach for a holiday or a claim, two things usually sit first in the queue, and it helps to know exactly what they do and do not cover.

ACC pays weekly compensation at up to 80% of your pre-incapacity gross earnings — but only when you cannot work because of an accidental injury, not an illness. Payments start after a one-week stand-down, from day eight ². The amount is capped: the maximum gross weekly compensation rose to $2,418.55 per week from 1 July 2025 ³, and ACC only insures earnings up to a maximum of $152,790 for the 2025/26 year, so income above that is not compensated ⁴. For full-time earners there is also a minimum, at least $752.00 gross per week ⁵. The critical limit for this topic is the first one: ACC is for injury. If you are off work through illness, ACC generally pays nothing.

Sick leave is the other first line. Under the Holidays Act 2003, eligible employees get a minimum of 10 days of paid sick leave a year, available after six months with the same employer ⁶. Ten days is helpful for a short illness, but it does not stretch to the months-long absence that does the financial damage.

So the realistic sequence for an illness is: sick leave covers the first days, then runs out; ACC does not apply because it is not an injury; and a repayment holiday only defers your mortgage while your income stays at zero. That sequence is exactly why income protection exists — to cover the illness gap that ACC, sick leave and a holiday between them leave open.

How do you build a real plan instead of relying on the bank?

A solid plan does not pick one tool; it stacks them so each covers what the next cannot. A few questions are more useful than any blanket rule:

• How long would sick leave and savings actually last? Map the weeks honestly. Most people find the buffer is shorter than they assumed.
• Is your risk injury, illness, or both? ACC handles injury up to its cap ²⁴. Illness is the larger uncovered exposure, and the one income protection is built for ⁷.
• How long could you go without income? This sets the wait period and benefit period on any cover, and tells you how far a short repayment holiday would really get you.
• What does your loan look like? A larger balance means capitalised interest during a holiday adds up faster, which raises the cost of relying on a deferral ¹⁸.

The mistake is not using a repayment holiday — it is treating the bank's deferral as your income plan. A holiday is a short bridge. ACC and sick leave cover the edges. Income protection is the layer that actually replaces income when illness keeps you off work for months. Used together, in that order, they leave far less to chance than any one of them alone.

Frequently asked questions

Is a mortgage repayment holiday the same as income protection? No. A repayment holiday pauses or reduces your mortgage payments while interest keeps accruing and is added to your loan, so your debt grows ¹. Income protection pays a monthly benefit to replace an agreed share of your income — commonly up to about 75% — while you cannot work through illness or injury ⁷. One defers a debt; the other replaces income.

Does interest still build up during a mortgage repayment holiday in NZ? Yes. A repayment holiday is a deferral, not forgiveness. Interest continues to be charged on the outstanding balance and is capitalised onto the loan, so you end the holiday owing more and usually with higher future repayments ¹. The larger the loan and the longer the holiday, the more it adds up ⁸.

Will ACC cover my mortgage if I am off work sick? Generally not. ACC pays weekly compensation only for accidental injury, at up to 80% of pre-incapacity earnings after a one-week stand-down, and it is capped ²³. If you are off work through illness rather than injury, ACC usually pays nothing — which is the gap income protection is designed to fill.

How long does a repayment holiday last, and is it guaranteed? It is typically a few months and is granted at the lender's discretion — you apply and the bank decides based on its criteria ¹. It is not an automatic right, so it may not be available exactly when you need it. Check your own lender's current terms rather than assuming.

Does income protection cover illness as well as injury? Most income protection policies cover a covered total or partial disability from illness as well as injury, replacing up to about 75% of pre-disability income, with the exact terms in each insurer's PDS ⁷. That illness cover is the main reason people hold it, because ACC handles injury but not illness ².

What sick leave am I entitled to before I would need cover? Under the Holidays Act 2003, eligible employees get at least 10 days of paid sick leave a year, available after six months with the same employer ⁶. That helps with short absences but not the months-long illness that causes real financial strain, which is where income protection fits.
