Reverse Mortgage vs Downsizing in New Zealand 2026 — Which Is Better?
Many New Zealanders reach retirement asset-rich (home) but cash-poor. Two main options to unlock that equity: stay in the home and take a reverse mortgage, or sell and downsize. Each has profound financial and lifestyle implications.
Downsizing releases equity tax-free, reduces ongoing costs, and avoids compound interest. A reverse mortgage keeps you in your home but accumulates debt that can erode 40–60% of your home's equity over 15–20 years. Downsizing is usually the better financial outcome; a reverse mortgage suits those who genuinely cannot or will not move, need modest cash access, and have other inheritance plans.
What Is a Reverse Mortgage?
A reverse mortgage allows homeowners (typically aged 60+) to borrow against the equity in their home without making regular repayments. Interest accumulates and is added to the loan balance. The loan is repaid when the home is sold, the owner dies, or they move into long-term care.
Key features:
- No regular repayments required
- Interest compounds continuously
- You retain home ownership
- Loan balance grows over time
- “No negative equity” guarantee — you’ll never owe more than the home’s value
Main NZ provider: Heartland Bank is the dominant reverse mortgage provider in New Zealand. Other providers have exited the market. Some building societies may offer limited products.
How Compound Interest Erodes Equity
This is the critical number most people don’t fully grasp. Interest on a reverse mortgage compounds — you pay interest on the interest.
Example: $200,000 reverse mortgage at 8% p.a.
| Year | Loan balance |
|---|---|
| 0 | $200,000 |
| 5 | $293,866 |
| 10 | $431,785 |
| 15 | $634,433 |
| 20 | $932,191 |
At year 20, the loan has grown to $932,191 from $200,000 — even though no new money was borrowed. If the home is worth $1,000,000 at that point, only $68,000 remains for the estate.
At current Heartland rates (typically 8.5–9.5% p.a. as of 2026 — verify directly), the effect is even faster.
How Downsizing Works
Selling the family home and buying (or renting) a smaller, more suitable property:
Example:
- Auckland home: $1,200,000
- Downsize to a 2-bedroom unit in Tauranga: $600,000
- Freed equity: $600,000 (tax-free — no capital gains tax on NZ primary residence)
- At 4% drawdown: $24,000/year supplementary income forever
Plus:
- Lower maintenance costs
- Lower rates and insurance
- Possibly lower or no mortgage
- Geographic flexibility (coastal, climate, near family)
Side-by-Side Comparison
| Factor | Reverse mortgage | Downsizing |
|---|---|---|
| Stays in current home | Yes | No |
| Upfront disruption | None | High (moving, settlement) |
| Equity released | Limited (borrowing against it) | Full (cash proceeds) |
| Ongoing cost | Interest compounding | Lower rates/maintenance |
| Estate impact | Significant reduction | Smaller home equity preserved |
| Tax | No income tax on loan proceeds | No CGT on primary home |
| Capital gains on home | Accrues to you, but offset by debt growth | Received tax-free on sale |
| Flexibility | Some — top-up available | High — cash is liquid |
| Availability in NZ | Heartland Bank (main provider) | Available anytime you choose |
When a Reverse Mortgage Makes Sense
A reverse mortgage is appropriate when:
- You genuinely cannot or will not move (strong emotional attachment to home, health barriers, community)
- You need modest cash access — not a full income stream (e.g., home repairs, medical costs, a lump sum)
- You have heirs who will receive the property (reducing their inheritance vs depleting savings may still leave an estate)
- You have a short life expectancy — interest has less time to compound
- All other retirement income (NZ Super, KiwiSaver) is in place and you need only a supplement
It is not appropriate when:
- You need large, regular cash flow — the debt compounds too fast
- You want to maximise your estate
- You could comfortably downsize and release the equity directly
The Maths: Reverse Mortgage vs Downsizing
Scenario: $1,000,000 Auckland home, 70-year-old, needs $200,000 over 10 years.
Option A: Reverse mortgage
- Borrow $200,000 at 9% p.a.
- After 10 years: loan balance = ~$473,000
- Home value (assuming 3% growth): ~$1,344,000
- Net equity remaining: ~$871,000
- But: you haven’t moved, you’ve maintained your lifestyle
Option B: Downsize immediately
- Sell for $1,000,000
- Buy Tauranga unit for $600,000
- Freed equity: $400,000
- After 10 years at 4% drawdown: have used ~$160,000 in draws, $240,000 remaining
- Plus lower annual costs (rates, insurance, maintenance) saving perhaps $5,000/year = $50,000 over 10 years
- Net wealth position materially stronger
Downsizing produces significantly better financial outcomes in almost every scenario. The trade-off is the lifestyle disruption of moving.
Tax Implications
Reverse mortgage: Loan proceeds are not income — no income tax. But if the reverse mortgage loan grows and reduces the estate significantly, there’s no tax issue — just less to leave behind.
Downsizing (selling primary home): No capital gains tax in NZ on a primary residence sale. The full proceeds are yours tax-free.
Important note: If you downsize and invest the freed equity in shares or funds, those investment returns are taxed at your PIR rate.
Getting Independent Advice
Before taking a reverse mortgage, Heartland Bank (and responsible practice) requires you to get independent legal advice. This is not a formality — understand:
- The interest rate and compounding effects on your specific loan
- The “no negative equity” guarantee terms
- Impact on estate and any family expectations
- Whether other options (downsizing, Government support) have been properly considered

What About Retirement Villages?
A third option exists between staying home and downsizing outright: entering a retirement village. This involves:
- Selling the family home
- Paying an entry contribution (Licence to Occupy)
- Ongoing weekly fees
