Mortgage Protection Insurance

Mortgage protection insurance (MPI) is a disability income product specifically structured around your mortgage repayment obligation. Unlike general income protection, which replaces a broad percentage of your salary, mortgage protection is calibrated to your exact mortgage repayment — covering the amount needed to keep your home loan current each month if illness or injury prevents you from working.

In New Zealand, the product is offered by the five major life insurers — AIA (Mortgage, Income or Rent Cover / MIRC), Partners Life (Mortgage Repayment Cover), Fidelity Life (Monthly Mortgage Repayment Cover), Asteron Life (Mortgage & Living Cover), and Chubb Life (Assurance Extra Mortgage Repayment Cover) — all distributed exclusively through licensed financial advisers.

The key financial parameter: benefit is capped at the lesser of 115% of your actual mortgage repayment or 45% of your gross pre-disability monthly income (for Chubb Life; other providers use a similar income-test approach). The 115% ceiling includes a buffer for rates, insurance, and body corporate levies that accompany property ownership. This means the policy is designed to keep your home, not to generate profit on top of your mortgage.

With the OCR at 2.25% and many borrowers refixing in 2026 at rates higher than their previous fixed terms, monthly repayments are under real pressure. NZ's total household debt to disposable income ratio remains one of the highest in the OECD, and the margin between income and repayments for many households is thin. In this environment, mortgage protection is a practical tool for preserving homeownership through income disruption.

Mortgage protection insurance in NZ activates on three main event categories. Total disability is the primary trigger: you must be unable to perform your own occupation (own-occ definition) or any occupation suited to your education and experience (any-occ definition) due to sickness or injury. Own-occupation definitions are more policyholder-friendly — a surgeon who loses a hand is disabled under own-occ even if they could technically work as a receptionist. Any-occupation is a tighter test.

Partial disability is covered by most NZ providers — if your disability reduces but doesn't eliminate your ability to work, you receive a proportional benefit. This is particularly valuable for knowledge workers who can work reduced hours during recovery. Asteron Life's Mortgage & Living Cover includes 29 specified injuries (broken bones, loss of limbs, burns) that pay immediately without needing to establish a disability threshold — you receive a lump sum regardless of whether you can work.

Death and terminal illness: on death, the outstanding mortgage balance is typically covered by a life insurance component (which may be a separate policy or a rider on the mortgage protection). On terminal illness diagnosis with less than 12 months prognosis, the benefit pays immediately.

Hospitalisation cover: Partners Life pays from the first night of hospitalisation, regardless of the standard waiting period. This rapid-response feature provides immediate support for unexpected hospital stays — a bypass surgery, cancer treatment commencement, or a serious accident resulting in ICU admission — before the standard disability assessment kicks in.

The waiting period is the time between your disability event and when the insurance benefit starts. It's the most impactful premium lever you control. NZ mortgage protection policies typically offer waiting periods of 4, 8, 13, 26, 52, or 104 weeks. Shorter waiting periods (4–8 weeks) mean you receive benefits sooner but pay significantly higher premiums. Longer waiting periods (26+ weeks) reduce premiums substantially but require you to self-fund for up to 6 months before benefits commence.

The right waiting period depends on your financial buffer. Rule of thumb: choose a waiting period equal to how long your emergency savings can cover your mortgage repayment. If you have 12 weeks of mortgage payments in savings, a 13-week waiting period is appropriate — you drain your savings over the waiting period, then the insurance kicks in at exactly the right moment. If you have no savings buffer, a 4-week waiting period may be necessary despite the higher cost.

For public servants and salaried employees with employer sick leave entitlements, consider your sick leave coverage. If your employer pays 3 months of salary on illness, a 13-week waiting period aligns your insurance with your employment benefit. Contracting arrangements or casual employment with minimal sick leave entitlement argue for a shorter waiting period.

The benefit period is the other key variable: most NZ policies offer 2 years, 5 years, or to age 65. For mortgage protection specifically, to-age-65 is the preferred option — your mortgage runs to age 65 or later, so you want coverage that lasts as long as the debt obligation.

Five providers dominate NZ mortgage protection insurance. AIA's MIRC is often cited for the AIA Vitality wellness integration — premium discounts for healthy behaviours tracked through a smartphone app. MIRC also waives the ACC offset for the first $7,500/month of benefit, meaning smaller ACC payments don't erode your AIA benefit. Benefit periods extend to age 70, the longest in the market. Available through AIA-authorised advisers.

Partners Life's Mortgage Repayment Cover calculates benefit as a daily rate (1/30th of the monthly sum per day) — eliminating the calendar month approximation other policies use. Payment from the first night of hospitalisation is a standout feature. Partners Life has a strong claims payment reputation among NZ advisers. Flexible waiting period reduction provisions allow policyholders to shorten their waiting period without medical underwriting after policy commencement.

Fidelity Life is NZ's largest locally-owned and operated life insurer (established 1973) and offers the highest maximum benefit: $30,000/month. The 2-week minimum waiting period is the shortest available from any NZ provider. Rehabilitation and retraining benefits are included — if disability prevents you from returning to your previous occupation, Fidelity covers retraining costs. Over $1.1 billion paid in claims since inception.

Asteron Life (part of Suncorp Group) includes 29 specified injury benefits payable without proving disability — a useful feature for physical workers. Annual 10% benefit increases available without medical underwriting, allowing the policy to keep pace with rising mortgage repayments over time. Mental illness cover available with a premium discount option.

Chubb Life's benefit period to age 55 suits younger borrowers, and the vocational retraining programme is among the most comprehensive in the market. Backed by the global Chubb group with strong financial ratings. All products are available through licensed adviser networks.

This is the most common question NZ homeowners ask. The short answer: they serve different purposes and many advisers recommend both for comprehensive coverage.

Mortgage protection insurance is a ring-fenced product. Its benefit is capped at your mortgage repayment and 115% of it. If your mortgage is $3,000/month, your benefit maxes at $3,450/month. It covers your housing obligation and nothing else. It's generally less expensive than income protection because the sum insured is lower.

Income protection replaces a percentage of your gross income — usually 75% — paid as a monthly benefit. For a $120,000/year earner, that's $7,500/month. This covers not just the mortgage, but all living expenses: groceries, utilities, school fees, car repayments, everything. IP is more expensive (higher sum insured) but more comprehensive.

For borrowers where 75% of income comfortably covers the mortgage and living costs, standalone income protection may be sufficient. For borrowers who are highly geared — where even a 75% income replacement would be tight — mortgage protection provides a guaranteed floor for the most critical expense (housing), while IP covers the broader income need.

Many NZ advisers structure it as: mortgage protection as the guaranteed-floor product ensuring the home is never at risk, plus IP as the comprehensive income replacement, with the two products working in tandem. See our comparison guide for a detailed breakdown.
