What is mortgage protection insurance?

Your mortgage is probably the biggest financial commitment you'll ever make. So what happens if illness, injury, or death made it impossible to keep up with the repayments? For most Kiwis, the answer is unthinkable — but it's exactly what mortgage protection insurance is designed to prevent.

Mortgage protection insurance is a flexible, affordable way to make sure you don't lose your home, even if the worst happens. Most people who take out a mortgage protection package combine two core covers: life insurance (which pays out a lump sum if you die) and mortgage protection (which replaces your income if you can't work due to illness or injury). Together, they can keep your home safe no matter what life throws at you.

This article explains how each cover works, how they fit together, and what to consider when thinking about protecting your mortgage.

What is mortgage protection insurance?

Mortgage protection insurance is a type of personal insurance designed to cover your mortgage repayments if you're unable to work. It's not a single product — it's usually a package of covers that work together to protect your home from two of the most common financial threats: your death, and your inability to earn an income.

The two core components most people include are:

• Life insurance — pays a lump sum if you die or are diagnosed as terminally ill, so your family can pay off the mortgage in full.
• Mortgage protection (income cover) — makes monthly payments toward your mortgage repayments if you can't work due to illness or injury.

Some people also add trauma insurance or total and permanent disablement (TPD) cover to their package for additional layers of protection. Whether or not these make sense depends on your personal circumstances and what other cover you have in place.

If you're a first home buyer or recently took out a new mortgage, our Kiwi home buyers' guide to life insurance is a good companion read to this article.

Life insurance and your mortgage

Life insurance is straightforward. If you die — for any reason — or are diagnosed as terminally ill (meaning your doctor expects you have 12–24 months or fewer to live, depending on your insurer), your insurer pays out a lump sum to your beneficiaries or estate.

When used to protect a mortgage, people often set their life insurance sum insured to match their outstanding mortgage balance. This means that if you were to die, your family could use the payout to clear the mortgage entirely, removing that financial burden at an already devastating time.

That said, there's no rule that says you can only insure your mortgage amount. Many people choose to insure more — to cover other debts, replace lost income for their family, or provide a financial buffer for their partner and children. Working out how much life insurance you need is worth thinking about carefully, particularly if your mortgage isn't the only financial concern your family would face.

What does life insurance cover?

Life insurance covers any cause of death — illness, accident, or otherwise. The standard exclusion across all policies is suicide within the first 13 months of taking out cover. Outside of that, you're covered regardless of the cause.

Some people also wonder whether factors like smoking or their BMI affect life insurance. They can — these factors are factored into your premium and sometimes into the underwriting decision. See how smoking affects insurance premiums here if that's relevant to your situation.

Mortgage protection cover explained

While life insurance handles the death scenario, mortgage protection insurance handles a different (and arguably more common) risk: being unable to work due to illness or injury.

If you're off work and can't earn an income, your mortgage payments don't pause. Mortgage protection insurance steps in to cover those repayments until you're back on your feet — or until your benefit period ends, whichever comes first.

Here's how it works in practice:

1. You choose an amount to insure — usually enough to cover your ongoing mortgage repayments.
2. You choose a wait period — how long you must be off work before payments begin.
3. You choose a payment period — the maximum length of time your insurer will make monthly payments.
4. If you become ill or injured and can't work, you make a claim. Once your wait period ends, your insurer starts paying.
5. Payments continue until you return to work, or until your payment period ends — whichever comes first.

It's also worth understanding how mortgage protection differs from income protection more broadly — this article comparing mortgage and income protection goes into more detail on that.

How wait and payment periods work

The wait period and payment period are two of the most important decisions you'll make when setting up mortgage protection cover. They directly affect how your policy pays out — and how much it costs.

Wait period

The wait period (sometimes called a stand-down or excess period) is the amount of time you need to be off work before your insurer starts making payments. Common options are 4 weeks, 8 weeks, 13 weeks, or 26 weeks.

A shorter wait period means payments kick in sooner — but it typically means a higher premium. A longer wait period is cheaper, but you'd need savings or sick leave to cover that gap. Many people choose a wait period that aligns with what their employer provides in sick leave, or with their available savings buffer.

Learn more about how wait periods work in income-style covers here.

Payment period

The payment period is the maximum length of time your insurer will make monthly payments in a single claim. Common options include 2 years, 5 years, or to age 65.

A shorter payment period (like 2 years) is more affordable and may be enough for most illness or injury scenarios. A longer payment period provides protection for extended conditions — but costs more. The right choice depends on your circumstances and what other financial safety nets you have in place.

What is and isn't covered

Mortgage protection insurance is designed to be broad — any health condition that genuinely prevents you from working is generally covered. This includes everything from broken bones and surgery recovery to mental health conditions, cancer, and chronic illness.

Standard exclusions

Every insurer has a set of exclusions — conditions or circumstances where the policy won't pay out. While these vary between insurers, some common ones include:

• Suicide or self-inflicted injury — usually excluded within the first 12 months of the policy.
• Pre-existing conditions — health conditions you had before applying may be excluded, depending on what you disclosed and how the insurer assessed your application.
• Redundancy — standard mortgage protection doesn't cover job loss due to redundancy. Some insurers offer this as an optional add-on, but it's not part of base cover.

Understanding exclusions before you take out cover is important. The underwriting process is where these are determined. Read more about how underwriting works here.

What about ACC?

ACC (the Accident Compensation Corporation) covers accidents in New Zealand — but it doesn't cover illness. If you break your leg slipping in the kitchen, ACC may provide some support. But if you're off work with cancer, depression, or a heart condition, ACC won't help. That's where mortgage protection insurance fills the gap.

See why ACC isn't always enough on its own here.

How much cover do you need?

For the mortgage protection (income) component, most people insure an amount that closely matches their regular mortgage repayments. This keeps the premium affordable while covering the most critical expense.

For life insurance, common considerations include:

• Your remaining mortgage balance
• Any other debts (personal loans, car loans, credit cards)
• Your partner's income and whether they could manage ongoing living costs without your contribution
• Whether you'd want to leave a financial buffer or replacement income for your family beyond just clearing the mortgage

There's no universal right answer — it comes down to your individual situation. This guide to working out how much life insurance you need walks through the common factors people consider.

How much does it cost?

The cost of mortgage protection insurance varies depending on a range of factors. For life insurance, key factors include your age, gender, whether you smoke, your health history, and the sum insured. For the mortgage protection (income) component, the wait period, payment period, and insured monthly amount all affect the premium.

Generally speaking, the younger and healthier you are when you take out cover, the lower the cost. Premiums can be either stepped (increasing each year as you age) or level (fixed for the life of the policy). Stepped vs level premiums is worth understanding if you're thinking about long-term affordability.

Because premiums vary significantly between insurers, comparing quotes is a useful step — the same cover can cost quite different amounts depending on who you go with.

How to make a claim

If you need to make a claim on your mortgage protection insurance, the process generally works like this:

1. Notify your insurer — contact them as soon as you know you'll be off work. Don't wait.
2. Complete claim forms — your insurer will require documentation, usually including a completed claim form and medical certificates from your doctor.
3. Wait period runs — your wait period begins from the date you first become unable to work.
4. Payments begin — once your wait period is complete and your claim is approved, your insurer will start making monthly payments directly to you.
5. Ongoing review — your insurer may request updated medical certificates to confirm you're still unable to work during a longer claim.

Mortgage protection vs income protection

Mortgage protection and income protection are similar — both pay out if you can't work due to illness or injury. The key difference is what they cover.

Mortgage protection is specifically designed to cover your mortgage repayments. Income protection is broader — it's typically designed to replace a percentage of your overall income (often up to 75%), which you can use for any living expenses, not just the mortgage.

Some people find that income protection provides more flexibility since it covers a wider range of expenses. Others prefer mortgage protection because it's targeted, simpler, and often more affordable. Many people consider both.

If you're self-employed or work variable hours, the income protection angle may be particularly relevant — see how income protection works when you're self-employed here.

Frequently asked questions

What does mortgage protection insurance cover?

Mortgage protection insurance makes monthly payments toward your mortgage repayments if you're unable to work due to illness or injury. It's designed to keep your home payments up to date during the period you're off work, continuing until you return to work or until your chosen payment period ends — whichever comes first.

Is mortgage protection the same as life insurance?

No — they're different products that protect against different risks. Life insurance pays a lump sum if you die or are terminally ill. Mortgage protection makes ongoing monthly payments if you can't work due to illness or injury. Most people who want comprehensive cover for their mortgage will consider both together.

Do I need mortgage protection if I have ACC?

ACC covers accidents in New Zealand but doesn't cover illness. If you're off work with cancer, a mental health condition, or any other sickness, ACC won't step in. Mortgage protection insurance covers illness as well as injury, filling a gap that ACC leaves. Read more about ACC and why it's not always enough here.

What is a wait period in mortgage protection insurance?

A wait period is the amount of time you need to be continuously unable to work before your insurer starts making payments. Common options are 4, 8, 13, or 26 weeks. A shorter wait period means faster access to payments but typically a higher premium. Many people choose a wait period that aligns with how much sick leave or savings they have available.

What is a payment period in mortgage protection insurance?

A payment period is the maximum length of time your insurer will make monthly payments during a single claim. Common options include 2 years, 5 years, or to age 65. Payments stop when you return to work or when the payment period ends — whichever happens first.

Does mortgage protection insurance cover redundancy?

Standard mortgage protection insurance covers illness and injury only — not job loss due to redundancy. Some insurers offer redundancy cover as an optional add-on. If job security is a concern, it's worth asking specifically about this when comparing options.

Can I insure more than just my mortgage repayments?

Yes. While many people insure an amount that matches their mortgage repayments, there's no requirement to limit the cover to that amount. You may choose to insure a higher amount to cover additional household expenses if you were unable to work.

What exclusions apply to mortgage protection insurance?

Common exclusions include pre-existing health conditions (those you had before applying), suicide or self-inflicted injury within the first 12 months, and redundancy (unless added as an optional extra). Your specific exclusions will depend on your health history and the insurer's underwriting decision.

How is life insurance sum insured calculated when protecting a mortgage?

Many people set their life insurance sum insured to match their outstanding mortgage balance so their family could pay it off entirely. Others insure more — to cover additional debts, replace lost income for their family, or provide a financial buffer. This guide to calculating your life insurance sum insured covers the common factors.

Can I take out mortgage protection if I'm self-employed?

Yes, mortgage protection insurance is available to self-employed people in New Zealand. Your income may be assessed differently during underwriting — for example, insurers may use your last 12 months of declared income. It's worth comparing options to find a policy that suits how your income is structured.

Will my premiums go up over time?

It depends on the premium structure you choose. Stepped premiums increase each year as you age. Level premiums remain fixed throughout the life of the policy, though they start higher. Understanding the trade-off between stepped and level premiums is useful for long-term planning. Compare stepped vs level premiums here.

Does mortgage protection insurance cover mental health conditions?

Mental health conditions can be covered by mortgage protection insurance if they prevent you from working. However, whether a pre-existing mental health condition is covered depends on your health history at the time of application and the insurer's underwriting decision. Some conditions may be excluded or covered with limitations.

When should I review my mortgage protection insurance?

It's worth reviewing your cover when your mortgage balance changes significantly (such as after refinancing or making a large lump sum payment), when your income changes, or when your family situation changes. Read about when to review your insurance cover here.

Can I bundle mortgage protection with other insurance?

Yes — it's common to hold mortgage protection alongside life insurance and, optionally, trauma or TPD cover. Bundling multiple covers doesn't always cost more, and it ensures different risks are all protected under a coordinated package. Read about the different types of personal insurance here.

What happens to my mortgage protection insurance if I move house or refinance?

Mortgage protection insurance isn't tied to a specific property or lender — it's a personal insurance policy. If you move or refinance, you can update your insured amount to reflect your new repayments. It's worth reviewing your cover at these moments to make sure it still matches your needs.
