How to Use Your Australian Equity to Buy in New Zealand
The deposit for a New Zealand property might already be sitting in your Australian home.
Right now the maths is unusually friendly. The Reserve Bank of Australia is holding at 4.35% after three hikes this year, while the Reserve Bank of New Zealand sits at 2.25%. The Australian dollar is strong, buying roughly NZ$1.23. So the equity you release here converts into a bigger deposit there, against a mortgage that costs less. As a New Zealand citizen and an Australian-licensed broker, this is the exact gap I help investors use.
Here is how the structure actually works, what you can and cannot do across the border, and the catches worth knowing before you move.
Why the window is open right now
Two things have lined up. First, the rate gap. Australia has been tightening into stubborn inflation while New Zealand has held low after its own easing cycle, so the cash rates are more than two percentage points apart. New Zealand mortgage pricing reflects that lower setting.
Second, the currency. A strong Australian dollar means every dollar of equity you pull out here stretches further once it lands in New Zealand dollars. Release A$200,000 and, at roughly NZ$1.23, that is about NZ$246,000 of buying power before costs.
I covered the rate story in detail in my piece on the cross-Tasman rate gap. This post is about the part people get wrong: how you actually fund the purchase.
The structure: you cannot pledge across the border
This is the single most misunderstood point. An Australian bank will not take a New Zealand house as security, and a New Zealand bank will not take your Australian one. There is no single cross-Tasman loan.
So the play is two separate pieces of lending that work together:
| Step | Where | What happens |
|---|---|---|
| 1. Release equity | Australia | An Australian lender lifts your home loan up toward 80% and releases the difference as cash. |
| 2. Move the deposit | Across the Tasman | Convert to NZD and hold it as your deposit. Watch the timing and the FX spread. |
| 3. Borrow the balance | New Zealand | A New Zealand lender funds the rest, secured only against the New Zealand property. |
Keeping the two loans cleanly separate is not just neat. It keeps you flexible to sell or refinance one side without untangling the other, and it keeps the tax trail clear in both countries.
How much you can release here
Your usable equity is 80% of your Australian property value minus what you still owe. Eighty percent is the line where you avoid Lenders Mortgage Insurance. Here is how it looks on an A$1,000,000 home with a A$550,000 loan.
Illustrative only. Usable equity = (value x 80%) minus current loan. Your lender confirms the value with a formal valuation.
So this owner can release about A$250,000 without touching their savings. At roughly NZ$1.23 that is close to NZ$307,000 of deposit, before currency costs. The deeper mechanics of equity release sit in my guide to using equity to buy an investment property.
Yes, Australians can buy there
New Zealand banned most foreign buyers in 2018, but Australian citizens were carved out under the free trade arrangement between the two countries. For ordinary residential property you do not need Overseas Investment Office consent.
There are edge cases. Some sensitive land, for example a title on an island or next to a lake, reserve or the coast, can still need consent. And a separate 2026 change lets certain investor-visa holders buy one high-value home above NZ$5,000,000, but as an Aussie citizen you do not need that pathway for a standard purchase. A New Zealand property lawyer confirms the position for the exact title before you sign.
What the New Zealand bank wants
Funding the deposit from Australian equity solves one side. The New Zealand lender still has to approve you. Under the Reserve Bank of New Zealand rules, investors typically need a 30% deposit on an existing property and around 20% on a new build, plus a debt-to-income limit that caps investor borrowing near seven times gross income.
New Zealand banks also shade overseas income and can be cautious with non-resident borrowers, so the lender you choose matters as much as the numbers. That is the part I line up before you ever make an offer, and it is the focus of my guide to why Aussie investors are buying New Zealand property.
Australia vs New Zealand, side by side
| For an investor | Australia | New Zealand |
|---|---|---|
| Central bank rate | 4.35% | 2.25% |
| Typical investor deposit | 10% to 20% | 30% existing, ~20% new build |
| Stamp duty | Yes, state based | None |
| Annual land tax | Yes, state based | None |
| Capital gains on sale | CGT applies | No broad CGT, but bright-line within 2 years |

The part most posts skip
You do not escape Australian tax. If you are an Australian tax resident, you are taxed on your worldwide income and gains, New Zealand rent and profits included. You usually get a foreign income tax offset for tax paid in New Zealand, so you are not taxed twice, but buying offshore does not put you outside the Australian system.
The bright-line catch. New Zealand has no broad capital gains tax, but if you sell a residential investment within 2 years of buying, the gain is generally taxed at your marginal rate. Plan to hold, not to flip.
Currency cuts both ways. A strong Australian dollar helps you buy in. But your loan, rent and any future sale are in New Zealand dollars, so a move the other way affects the value of it all when you convert back.
Rates are not fixed unless you fix them. The equity you release here is usually on a variable rate that moves with the lender, so do not assume today's repayment is locked in unless you have specifically chosen a fixed rate.
You carry two loans. A bigger loan on your Australian home plus a new mortgage in New Zealand. Build in a buffer rather than borrowing to the absolute limit on both. This is general information, not tax or financial advice. Get advice specific to your situation.

FAQs
Can I use my Australian property as security for a New Zealand loan?+
Generally no. Australian lenders take security over Australian property, and New Zealand lenders take security over New Zealand property. They do not lend across the border. The usual structure is to release equity from your Australian property with an Australian lender, take that as cash, and use it as the deposit on a separate New Zealand mortgage held with a New Zealand lender against the New Zealand home.
Are Australians allowed to buy residential property in New Zealand?+
Yes. Australian citizens are exempt from New Zealand's overseas buyer ban under the free trade arrangement between the two countries, so for ordinary residential property you do not need Overseas Investment Office consent. Some sensitive land, for example land on an island or next to a lake or reserve, can still need consent. A New Zealand property lawyer confirms this for the specific title.
How much deposit do I need to buy in New Zealand?+
For an existing investment property, New Zealand banks typically want a 30% deposit, and around 20% for a new build, under the Reserve Bank of New Zealand loan-to-value rules. There are also debt-to-income limits, with investors generally capped near seven times gross income. Your Australian equity can fund that deposit, but the New Zealand bank still has to be comfortable servicing the loan.
Does buying in New Zealand let me avoid Australian tax?+
No, and it is important to be clear on this. If you are an Australian tax resident, you are taxed on your worldwide income and gains, including rent and any taxable profit from a New Zealand property. You usually get a foreign income tax offset for tax paid in New Zealand so you are not taxed twice, but you do not escape the Australian system by buying offshore. Get advice from an accountant who works across both countries.
Is there capital gains tax in New Zealand?+
New Zealand has no broad capital gains tax, but it does have the bright-line test. If you sell a residential investment property within 2 years of buying it, the gain is generally taxed at your marginal rate. Hold beyond the bright-line period and that specific rule does not apply, though other land-tax rules can still catch a sale, and your Australian tax position is separate.
Why does the strong Australian dollar matter for this?+
When the Australian dollar buys more New Zealand dollars, the equity you release in Australia converts into a larger deposit across the Tasman. In late June 2026 one Australian dollar bought roughly NZ$1.23. That said, currency moves both ways, and your New Zealand loan, rent and any future sale are all in New Zealand dollars, so there is real exchange-rate risk to plan for.
