If you’re approaching retirement and wondering how to access your home’s equity without selling, a reverse mortgage might have crossed your mind. This financial product allows homeowners aged 60+ to borrow against their property while continuing to live there — but it’s crucial to understand exactly how they work in New Zealand before making any decisions.
What exactly is a reverse mortgage and how does it work?
A reverse mortgage is essentially the opposite of a traditional mortgage. Instead of making monthly payments to a lender, the lender pays you — either as a lump sum, regular payments, or a line of credit you can draw from. The loan is secured against your home, and you retain ownership while living there.
Here’s the key difference: unlike a regular mortgage where your debt decreases over time, with a reverse mortgage your debt grows. Interest compounds on the borrowed amount, meaning you owe more each year. The loan is typically repaid when you sell the home, move into care, or pass away.
In New Zealand, reverse mortgages are offered by a handful of lenders, with Heartland Bank being the main provider. The maximum you can borrow depends on your age, your home’s value, and current interest rates — typically ranging from 15% to 45% of your property’s value.
The takeaway: Reverse mortgages let you access equity without selling, but the debt grows over time through compound interest.
Who can get a reverse mortgage in New Zealand?
Not everyone qualifies for a reverse mortgage. The eligibility criteria are quite specific, and lenders are strict about who they’ll approve.
You must be at least 60 years old (some lenders require 65+), own your home outright or have a very small existing mortgage, and the property must be your primary residence in New Zealand. The home also needs to meet certain standards and be worth at least $200,000 in most cases.
Importantly, if you’re married or in a de facto relationship, both partners must meet the age requirement. This is because the loan terms are based on both your life expectancies. You’ll also need to demonstrate you can maintain the property and pay rates, insurance, and other ongoing costs.
According to recent industry data, the average reverse mortgage borrower in New Zealand is 72 years old and borrows around $150,000 against a property worth $600,000.
Lenders will also consider your overall financial situation. While you don’t need regular income to qualify, they want to ensure you can sustain homeownership costs throughout the loan term.
The takeaway: Eligibility is age-based (60+) with strict property and financial criteria that both partners must meet.
What are the real costs and risks involved?
Understanding the costs is absolutely critical before proceeding with a reverse mortgage. These loans are expensive compared to traditional mortgages, and the costs compound over time.
Interest rates are typically 2-4% higher than standard mortgage rates. As of April 2026, reverse mortgage rates range from 7-9% annually. There are also establishment fees (often $2,000-$4,000), legal fees, valuation costs, and ongoing service fees.
But the biggest cost is the compound interest. Let’s say you borrow $100,000 at 8% interest. After 10 years, you’d owe approximately $216,000. After 20 years, it could be $466,000. This dramatically reduces the equity you can leave to family.
| Years | Original Loan | 8% Interest Rate | Total Owed |
|---|---|---|---|
| 5 years | $100,000 | Compounding | $147,000 |
| 10 years | $100,000 | Compounding | $216,000 |
| 15 years | $100,000 | Compounding | $317,000 |
| 20 years | $100,000 | Compounding | $466,000 |
Other risks include potential changes in property values, the impact on your estate, and possible effects on pension eligibility if you receive large lump sums.

The takeaway: High interest rates and compound growth make reverse mortgages expensive, potentially consuming most of your home’s equity over time.
What are the alternatives to consider?
Before committing to a reverse mortgage, it’s worth exploring other options that might better suit your needs and cost less over time.
Downsizing is often the most financially sensible choice. Selling your current home and buying something smaller could free up significant cash while reducing maintenance costs and rates. Yes, moving can be emotional, but the financial benefits are usually substantial.
A home equity loan from traditional lenders like ANZ, ASB, BNZ, Westpac, or Kiwibank might be cheaper if you have some income to service payments. Some retirees use their KiwiSaver funds strategically or consider investment properties as alternative income sources.
Renting out part of your home (like a sleepout or spare room) can provide ongoing income without debt. Family financial arrangements, where adult children help with a formal agreement, can also work well for some families.
For those needing aged care, investigating subsidies and support options might be more appropriate than borrowing against your home.
The takeaway: Downsizing, traditional loans, or KiwiSaver strategies often provide better value than reverse mortgages.
When might a reverse mortgage actually make sense?
Despite the costs, reverse mortgages can be appropriate in specific situations where other options aren’t viable or practical.
They work best when you’re determined to stay in your current home, have significant equity, are in good health with potentially shorter life expectancy, and have minimal other assets or income sources. If leaving an inheritance isn’t a priority, the higher costs might be acceptable for the lifestyle benefits.
Reverse mortgages can also suit people who want to access equity for home modifications (like disability access), travel, or other immediate needs while maintaining homeownership. Some borrowers use them strategically to delay claiming NZ Superannuation or to manage tax situations.
The key is ensuring you fully understand the long-term implications and have explored all alternatives with professional advice.
The takeaway: Reverse mortgages suit specific situations where staying in your home outweighs the financial costs and other options aren’t feasible.
Bottom Line
Reverse mortgages are complex financial products with significant long-term costs. While they can provide access to your home’s equity without selling, the compound interest means they’re expensive over time. For most New Zealanders, downsizing or other alternatives offer better financial outcomes.
If you’re considering this option, get independent financial advice and involve your family in discussions. As an experienced NZ mortgage adviser, I always recommend exploring every alternative before committing to a reverse mortgage.
