Losing your income while holding a mortgage is one of the most financially damaging scenarios a NZ homeowner can face. Mortgage protection insurance — and related products like income protection and life insurance — exists to keep your mortgage repayments covered when you can’t work. Understanding which product actually protects you (and what the exclusions are) is essential before paying for coverage.
Mortgage repayment insurance pays your mortgage directly if you're unable to work due to illness, injury, or redundancy. Income protection insurance is broader — it pays up to 75% of your pre-disability income regardless of what you use it for. Income protection is generally considered better value. Life insurance and trauma cover address different risks (death and serious illness). Talk to an independent financial adviser — many of these products are complex and exclusions matter enormously.
Types of Insurance That Protect Your Mortgage
1. Mortgage repayment insurance (MRI)
Also called “mortgage protection” or “repayment protection”. Pays your mortgage repayments (or a fixed amount equal to them) for a defined period if you:
- Cannot work due to illness or injury (disability cover)
- Are made redundant (redundancy cover)
- Die (life cover element, if included)
Typical benefit period: 12–24 months per claim (not indefinitely) Waiting period: Usually 30–90 days before payments begin Cost: Varies by age, health, and loan size — roughly $50–$150/month for a typical $500,000 mortgage
2. Income protection insurance
Broader than MRI — pays up to 75% of your pre-disability gross income (not tied to your mortgage). You can use it for any expense: mortgage, living costs, school fees, etc. Available as:
- Agreed value: Agreed sum paid regardless of your income at claim time (more expensive, better for self-employed)
- Indemnity: Pays based on your income at claim time (cheaper, can pay less if income fluctuated)
Benefit period: Can be 2 years, 5 years, or to age 65 — the longer the better (at a cost) Waiting period: 4, 8, 13, or 26 weeks — longer waiting period = lower premium Cost: Typically 1–3% of covered income annually; premiums are often tax-deductible if the benefit would be taxable
3. Life insurance / mortgage life insurance
Pays a lump sum on death. Many homeowners set the sum insured to equal (or exceed) their outstanding mortgage. This ensures the surviving partner is mortgage-free. Some policies are “decreasing” — the sum insured reduces in line with the mortgage balance, making them cheaper.
4. Trauma / critical illness cover
Pays a lump sum on diagnosis of a specified serious condition (cancer, heart attack, stroke, etc.). This lump sum can be used to pay down the mortgage, fund treatment, or cover income while recovering. Not income protection — it pays once on diagnosis.
5. Total and permanent disability (TPD)
Pays a lump sum if you become permanently unable to work. Often bundled with life insurance.
What’s Typically Excluded
Mortgage repayment insurance exclusions are extensive. Common exclusions:
- Pre-existing medical conditions (often excluded for 12–24 months)
- Self-inflicted conditions
- Redundancy that was foreseeable (e.g. employer announced restructuring before you took the policy)
- Casual, contract, or seasonal employment (redundancy cover often limited to permanent employees)
- Mental health conditions (some policies exclude or restrict)
- First 30–90 days of a claim (waiting period)
- Business owners / self-employed (redundancy cover rarely available)
Income protection exclusions are also significant. Always read the policy wording — marketing documents and policy documents can differ substantially.

Do You Need Mortgage Protection Insurance?
Consider your financial resilience if your income stopped tomorrow:
- How long could you cover mortgage repayments from savings? Less than 3 months = significant risk
- Does your employer provide sick leave? NZ employees get 10 days/year — not adequate for long illness
- Do you have ACC cover? ACC covers work and non-work accidents (not illness) and replaces 80% of income up to a cap
- Do you have a partner’s income? A dual-income household has some natural resilience
- What’s your KiwiSaver balance? In genuine hardship, significant illness or permanent disability may allow early withdrawal
ACC covers accidents — not heart attacks, cancer, or mental health episodes. If your biggest risk is illness (as it statistically is), income protection is more valuable than redundancy cover.
Getting Advice
Mortgage protection products are sold by banks, insurance companies, and financial advisers. Banks often sell MRI at the point of mortgage settlement — convenient, but not necessarily the best value or coverage. An independent financial adviser (one paid by fee, not commission) can compare the market and recommend appropriate coverage. Many Kiwis are over-insured in some areas and dangerously under-insured in others.
Frequently Asked Questions
Is mortgage protection insurance compulsory in NZ?
No — it is never compulsory. Banks may offer it alongside your mortgage but cannot require it as a condition of lending.
What’s better — MRI or income protection?
Income protection is generally considered superior because it’s not tied to your mortgage balance, covers any use of funds, and often provides benefits to age 65. MRI benefits are usually limited to 12–24 months. If you can only afford one, income protection is typically the better choice.
Is income protection tax-deductible in NZ?
If you’re employed and pay the premiums personally, income protection premiums are not tax-deductible in NZ (unlike Australia). However, if your employer pays the premiums as part of a group scheme, the benefit would be taxable when paid. Get tax advice on your specific structure.
Does ACC affect income protection claims?
Yes — most income protection policies are offset by ACC payments. If ACC is paying 80% of your income after an accident, your income protection will only top up to the agreed benefit level. This is standard and prevents over-insurance.
How do I make sure I’m comparing policies properly?
Use a registered financial adviser to compare policies on a like-for-like basis. Key comparison points: agreed vs indemnity value, waiting period, benefit period, definition of disability (own occupation vs any occupation), and exclusion list. The cheapest policy is rarely the best.
