Should Australians Move to New Zealand to Avoid Capital Gains Tax?

Australia has just proposed some major changes to its capital gains tax regime, and a lot of Australians are suddenly weighing up their options. Australia taxes capital gains on almost every investment asset you can name, shares, investment properties, business assets, crypto, even collectables in some cases.

New Zealand, on the other hand, famously doesn't have a general capital gains tax. So on paper it sounds almost too good to be true: move to Queenstown, enjoy the scenery, and leave the tax man behind.

Except there are at least three catches most people never hear about, and they can make the difference between moving to New Zealand saving you a fortune or making almost no difference at all.

New Zealand doesn't have a general CGT, but that doesn't mean your investments are automatically tax-free, Australia can still tax you on the way out, and which country actually wins depends entirely on what you own.

What happens to your Australian tax residency when you move to NZ?

Just because you pack your bags for New Zealand doesn't mean the Australian Tax Office simply waves goodbye. Australia taxes residents on their worldwide income, and to stop paying Australian tax you genuinely need to sever your Australian tax residency, which usually means significantly cutting your economic and social ties to Australia and establishing a permanent home overseas.

That's the first hurdle. Get your residency status wrong, and none of what follows in this article matters much.

Does Australia have an exit tax when you leave for New Zealand?

Yes, and this is the catch that catches people out. When you cease Australian tax residency, the ATO can treat certain assets, including shares, ETFs and crypto, as if you sold them at market value the moment you left, even though you still own them. That means you could end up with a tax bill without having sold a single share.

Australian real estate is generally treated differently, since Australia continues to tax gains on Australian property even after you've become a foreign resident. The US has a similar concept, sometimes called the "Saverin tax" after Facebook co-founder Eduardo Saverin, who renounced his US citizenship and in the process avoided an eight-figure CGT bill. Australia's exit tax exists for the same reason: to stop people simply moving overseas to sidestep tax.

There are exceptions and the rules vary by asset type, so not everyone gets hit the same way. But the key point stands, moving to New Zealand is not an automatic quick fix for your tax bill. Understanding what happens when you cease Australian tax residency is the most important step in the whole process. Get it wrong and you could owe Australian tax before you've had your first pie in New Zealand.

Does New Zealand actually tax capital gains?

Say you've cleared that first hurdle and you're now living in New Zealand. This brings up catch number two, and it's one recent Aussie media coverage has got wrong. New Zealand doesn't have a general capital gains tax, but that doesn't mean every capital gain is tax-free.

The difference comes down to what each tax authority actually asks. In Australia, the ATO asks whether you made a capital gain. In New Zealand, the IRD is more focused on why you bought the asset in the first place. That distinction changes everything about how you get taxed.

How does New Zealand's bright-line test tax property sales?

New Zealand's bright-line test is the closest thing it has to a property CGT. Under current rules, selling a residential property within two years of buying it can make any profit taxable, unless an exclusion applies. The main home is generally excluded, along with things like business premises and farmland, but investment property is exactly where this trap lives.

Even outside the bright-line window, a property sale can still be taxable if you bought with the intention of reselling, have a regular pattern of buying and selling, or are in the business of property dealing, development or building. So while New Zealand doesn't have a blanket property CGT, profits aren't automatically exempt either.

Are shares and ETFs tax-free in New Zealand?

For most everyday investors buying shares or ETFs as long-term holdings, New Zealand generally doesn't tax the capital gain when you eventually sell. Buy at $100, sell a year later for $120, and that $20 gain is typically tax-free, one of the biggest differences from Australia's system.

The exception is intention and pattern again. If you're effectively running a business of trading shares, buying and selling frequently with the aim of making short-term profits, the IRD can deem you a trader and tax those gains as ordinary income instead.

What is the FIF regime and why does it catch new migrants out?

This is the one many Australians don't see coming. New Zealand has a Foreign Investment Fund (FIF) regime for overseas shares. Once your overseas investments exceed a threshold, currently $50,000 and set to rise to $100,000 later in the year, you may owe tax annually even if you haven't sold anything and your portfolio hasn't produced any income.

It's a completely different mechanism to a capital gains tax, since it can tax you on a deemed return whether or not you've actually made a gain, but it can still create a tax bill that catches new migrants by surprise. New Zealand isn't tax-free on investments, it just taxes them differently, and that distinction matters a lot depending on what you hold.

Which country is better for property investors: Australia or New Zealand?

Even once you understand the exit tax and the FIF rules, there's a final mistake people make: assuming New Zealand is automatically the better outcome. It isn't, and the answer depends almost entirely on what you own.

If most of your wealth is tied up in Australian property, moving to New Zealand may not solve much. Australia can generally still tax Australian real estate even after you become a foreign resident, so rental income and any eventual sale gain can still fall within the Australian tax net.

Which country is better for share investors: Australia or New Zealand?

If you mainly hold Australian or New Zealand shares as a long-term investor, New Zealand looks attractive, since long-term gains on those shares generally aren't taxed. In Australia, gains are usually taxable on sale, though you can get a 50% CGT discount for holding more than 12 months.

Foreign shares and global ETFs are where it gets more complicated. Australia taxes dividends as they arrive and capital gains when you eventually sell. New Zealand's FIF rules can instead tax you every year on a deemed return once your foreign portfolio is large enough, whether or not you've sold anything. For an Aussie with a large global portfolio, Australia's system, where tax is often delayed until sale and discounted for long holds, might actually work out better.

How does New Zealand tax cryptocurrency compared to Australia?

Crypto is where the two systems look most different. Australia has a relatively clear framework, treating cryptocurrency as a CGT asset in most cases. Buy Bitcoin for $10,000, sell it later for $50,000, and you've generally made a capital gain, with the normal CGT rules and the 12-month discount applying if you've held long enough.

New Zealand's intention-based approach shows up hardest here. If your purpose in buying crypto was to sell or exchange it for a profit, those gains are generally taxable as income, at your marginal tax rate rather than a discounted capital gains rate. That makes the New Zealand outcome much more subjective than Australia's.

So, should Australians move to New Zealand to avoid CGT?

The better question isn't whether to move, it's which country gives a better outcome for your specific assets. A property investor, a share investor, a crypto investor and someone holding global ETFs could all land on completely different answers. New Zealand may work out better for some people, Australia may still be better for others, and plenty of investors will land somewhere in between.

Before anyone packs for Queenstown purely for tax reasons, this is exactly the kind of situation where proper cross-border tax advice earns its cost. Getting the exit tax, bright-line, and FIF rules right can make the difference between moving being a genuine tax win and an expensive surprise.

Frequently Asked Questions

Does Australia tax you when you leave the country, even if you don't sell anything?

Potentially, yes. Australia's exit tax rules can treat assets like shares, ETFs and crypto as sold at market value the moment you cease Australian tax residency, creating a tax bill even though you still hold the asset. Australian real estate is generally taxed differently and can remain in Australia's tax net after you leave.

Do I have to pay tax on my KiwiSaver-style shares once I live in New Zealand?

Long-term investors generally don't pay tax on capital gains from NZ shares or most listed Australian shares when they sell. The exception is if the IRD considers you to be trading shares as a business, buying and selling frequently with the intention of short-term profit, in which case gains are taxed as ordinary income.

What is the FIF threshold and is it changing?

The Foreign Investment Fund threshold currently sits at $50,000 of overseas investment cost, above which you can be taxed annually on a deemed return regardless of whether you've sold or earned anything. It's set to rise to $100,000 later in the year.
