Mortgage Protection Insurance in NZ: Is It Worth It?

What is mortgage protection insurance?

Mortgage protection insurance is designed to pay off your mortgage — or cover your repayments — if you die, become terminally ill, or in some policies, if you suffer a serious illness or disability. It's usually offered by your bank when you take out a home loan.

The concept sounds essential, and for many people some form of mortgage cover genuinely is. But it's important to understand exactly what you're getting and whether a standalone insurance policy might actually serve you better.

Bank-offered vs standalone insurance

This is the critical comparison that most Kiwis don't make. Here's how bank mortgage protection typically compares to standalone life insurance:

Bank mortgage protection

• Decreasing cover — The payout reduces as your mortgage balance reduces. After 15 years of paying your mortgage down, you have significantly less cover — but you're often paying the same (or higher) premiums.
• Limited scope — Often covers accidental death and injury only, not illness. Some policies are more comprehensive, but check the details carefully.
• Mortgage-only payout — The benefit pays off the remaining mortgage balance and nothing more. Your family doesn't receive extra for living expenses, education costs, or anything else.
• Tied to your bank — If you switch banks or refinance, you may lose your cover and need to reapply — potentially at a higher premium if your health has changed.
• Limited insurer choice — Your bank partners with one insurance company. You don't get to compare across the market.

Standalone life insurance

• Fixed cover — If you take out $500,000 of life cover, your family gets $500,000 regardless of how much mortgage you've paid off. As your mortgage reduces, the "surplus" becomes available for living expenses, education, or whatever your family needs.
• Broader cover — Covers death from any cause (accident or illness), plus terminal illness benefit as standard.
• Flexible payout — Your family receives a lump sum they can use for anything — mortgage, living costs, education, debt clearance.
• Portable — Your policy stays with you regardless of which bank holds your mortgage. Switch banks freely without affecting your cover.
• Often cheaper per dollar — Standalone policies from specialist insurers frequently provide better value than bank-offered products.

Do I need it?

If you have a mortgage and anyone depends on your income: yes, you need some form of cover. The question is which type suits you best.

Here's a simple decision framework:

• If you already have adequate life insurance that would cover your mortgage balance and more — you probably don't need separate mortgage protection. Your existing cover already handles it.
• If you have NO life insurance and a new mortgage — get something in place immediately. Even bank mortgage protection is better than nothing while you explore standalone options.
• If your existing life cover is less than your mortgage balance — either increase your life cover or consider adding mortgage protection to fill the gap.

What does it typically cost?

Costs vary significantly depending on your age, health, mortgage size, and the type of cover. Here's a rough comparison for a healthy 35-year-old:

• Bank mortgage protection ($500,000 mortgage): approximately $80–$120 per month — but remember, this is decreasing cover that reduces as you pay down your mortgage.
• Standalone life insurance ($500,000 fixed cover): approximately $40–$70 per month — and this amount stays the same throughout the policy. Your family gets the full $500,000 regardless of your remaining mortgage balance.

The standalone option often provides better value, especially in the later years of your mortgage. With bank protection, you might be paying $100/month for $200,000 of cover (because your mortgage has reduced). With standalone, you're still covered for the full $500,000.

The first-home buyer decision

You've just bought your first home. The bank is offering mortgage protection. You're already financially stretched. What should you do?

1. Don't skip insurance entirely — This is when you're most vulnerable. You have maximum debt, possibly a growing family, and limited savings. Going uninsured is a significant risk.
2. At minimum, ensure you and your partner both have life cover equal to at least the mortgage balance. If one of you died, the other needs to be able to keep the home.
3. Consider starting with the bank's product if it's quick and easy — Getting some cover immediately is the priority. But commit to reviewing standalone options within 6 months.
4. Income protection is worth considering too — Being unable to work due to illness (not covered by ACC) is statistically more likely than death. If you can only afford one product beyond life cover, income protection is often the better choice.
5. Talk to a financial adviser — Most advisers offer free consultations. They can review your situation, compare options across multiple insurers, and set up a package that fits your budget. There's no cost to you — they're paid by the insurer.
