A reverse mortgage allows NZ homeowners aged 60+ to access equity from their home without selling or making regular repayments. Interest compounds onto the loan balance over time. The appeal is real — but so is the compound interest risk, which erodes equity faster than most borrowers expect.
Heartland Bank is New Zealand's primary reverse mortgage provider. Minimum age is 60. You can borrow up to 15%–45% of your property value depending on your age, with no regular repayments required. The loan — plus all compounded interest — is repaid when the property is sold. Interest compounds monthly at rates currently around 8%–9%, which can double a loan balance in approximately 8–9 years.
What Is a Reverse Mortgage?
A reverse mortgage is a loan secured against your home where:
- No regular repayments are required — interest accrues and is added to the loan balance
- You continue to live in your home — the loan is not repayable until you sell, move into care permanently, or die
- The loan is repaid from sale proceeds — including all compounded interest
This makes reverse mortgages distinct from standard mortgages, where principal and interest are repaid progressively. With a reverse mortgage, the debt grows over time.
Heartland Bank: New Zealand’s Main Provider
Heartland Bank is the dominant reverse mortgage provider in NZ, with a long-established product and a significant market presence. Key terms as of 2026 (verify directly with Heartland for current rates):
- Minimum age: 60 years (co-borrower must also be 60+)
- Maximum loan amount by age: Approximately 15%–20% of property value at age 60, increasing by ~1% per year of age to approximately 45% at age 85+
- Interest rate: Variable, currently approximately 8%–9% per annum (significantly above standard mortgage rates)
- No negative equity guarantee (NNEG): Heartland commits that you will never owe more than the value of your home, regardless of how much the balance has grown
The NNEG is an important consumer protection — in a falling property market, it caps your liability at the sale proceeds.
A small number of other lenders offer reverse mortgage-type products in NZ, including some credit unions, but Heartland holds the majority of the market.
How Compound Interest Works on a Reverse Mortgage
This is the feature most borrowers underestimate. Interest is charged on the loan balance each month, then added to that balance — which means next month, you’re charged interest on the original loan plus the previous month’s interest.
Example: $100,000 reverse mortgage at 8.5% compounding monthly
| Year | Balance |
|---|---|
| Start | $100,000 |
| 5 years | ~$151,600 |
| 10 years | ~$229,700 |
| 15 years | ~$348,400 |
| 20 years | ~$528,000 |
At 8.5% compounding, the balance roughly doubles every 8–9 years. A borrower who takes $100,000 at age 65 and lives to 85 may owe over $500,000 by the time the property is sold — having never made a single repayment.
This is not a criticism of the product — the trade-off is clear. But many borrowers focus only on the amount borrowed and not on the final balance.
What Can You Use a Reverse Mortgage For?
NZ borrowers most commonly use reverse mortgages for:
- Supplementing retirement income — converting equity to a regular drawdown
- Large one-off expenses — medical costs, home modifications, travel
- Gifting to children — helping with deposits for family members
- Home renovations — modifying the property to support ageing in place
- Paying off remaining standard mortgage debt
Heartland’s product can be structured as a lump sum, regular drawdown, or a combination.
The “Asset-Rich, Cash-Poor” Situation
Reverse mortgages most commonly suit homeowners who:
- Own their property outright or have very low remaining mortgage debt
- Have limited other assets or superannuation income
- Want to remain in their home
- Have heirs who are aware of and comfortable with the arrangement
Family communication is important — a reverse mortgage reduces the equity available to pass on as an inheritance. Most families who have transparent conversations about this navigate it successfully; problems arise when children discover the arrangement only after a parent’s death.
Alternatives to a Reverse Mortgage in NZ
Before committing to a reverse mortgage, consider:
Downsizing Selling the current property and purchasing a smaller, lower-value home releases equity as cash without compounding interest. This is the most financially efficient option for those willing to move.
KiwiSaver (after age 65) NZ Super plus KiwiSaver withdrawals provide a combined income floor. KiwiSaver balance can be withdrawn in full or part after age 65.
Renting a room Tax-free boarding income of up to $230/week from a resident boarder (IRD rules) provides supplementary income without touching equity.
Home equity loan with repayments If you can manage some repayments, a standard home equity loan (top-up) at mortgage rates (~5.5%–6.5%) is substantially cheaper than a reverse mortgage at 8%–9%.
Government assistance Work and Income NZ (WINZ) provides supplementary income assistance, accommodation supplement, and other support to eligible retirees. Check your eligibility before accessing equity.
Frequently Asked Questions
What is the minimum age for a reverse mortgage in NZ?
Heartland Bank requires borrowers to be at least 60 years old. All borrowers on the loan (including co-borrowers) must meet this minimum age requirement.
How much can I borrow with a reverse mortgage in NZ?
Heartland’s maximum loan is approximately 15%–20% of your property value at age 60, increasing by roughly 1% per year of age. At age 75, the maximum is approximately 25%–30% of property value. All borrowers on a property worth $900,000 at age 70 might access approximately $180,000–$225,000.
Is a reverse mortgage safe in NZ?
The no negative equity guarantee (NNEG) means you will never owe more than the proceeds from selling your home. Your estate is protected from shortfalls. However, the compounding interest is a real risk to equity — understand the projected balance at likely sale before committing.
What happens to a reverse mortgage if the borrower moves into care in NZ?
The loan becomes repayable when the borrower permanently moves into care (e.g., a rest home or hospital) or passes away. The property is sold, the loan and compounded interest are repaid from proceeds, and any surplus goes to the estate.
Can I repay a reverse mortgage early in NZ?
Yes — Heartland allows voluntary repayments at any time without penalty. Making even modest voluntary repayments slows the compounding effect significantly and preserves equity.
