Last week a message arrived in my LinkedIn notifications. Polite, well written, addressed to me by name. It made its case in about eighty words.

I am not naming the company or the person who sent it. They may well be perfectly reputable, and naming them would miss the point. The claims are the subject here, not the sender, and the same claims are being made right across the sector.

Here is what matters. I spent the better part of a week checking that message against Inland Revenue, the Australian Taxation Office, Land Information New Zealand, the Reserve Bank of New Zealand, REINZ, Cotality and Stats NZ. Every factual claim in it is accurate.

And the investment still does not stand up.

That gap between accurate and sound is where investors get hurt. Nobody sells a bad deal with a lie any more. They sell it with a carefully chosen set of true statements, arranged so the reader fills in the rest themselves. It is important to understand that the omission is the product.

Read down that table and the shape of it is clear. New Zealand wins decisively at the front door and loses almost everywhere after it. The saving is a one-off at purchase. The disadvantages are annual, and several of them compound.

Tax leads the pitch because tax feels like certainty

Everything else in a property investment is a forecast. Growth is a forecast. Rent, vacancy, maintenance, the exit price, all forecasts. Tax feels like a number you can bank.

So look at what came first in that message, and at what never appeared at all. No vacancy figure, no operating costs, no yield, no growth record, no resale evidence. Three tax points and a deposit structure, and by the time you reach the price you have been given the impression the hard questions are settled. For this reason, when the first thing you are sold is a tax outcome, the discipline is to ask what that tax outcome is standing in for.

The advantage that does not survive the border

Take the strongest claim. New Zealand has no broad capital gains tax. Correct.

It is also close to irrelevant to an Australian tax resident, because Australia taxes its residents on worldwide gains. Sell a New Zealand property at a profit and Australia assesses that gain, in Australian dollars, under Australian rules.

And the Australian rules have just changed in a direction that makes this worse rather than better. Under the reforms legislated following the May 2026 Budget, from 1 July 2027 the fifty per cent capital gains discount for individuals, partnerships and trusts is replaced by indexation of the cost base and a minimum thirty per cent tax rate on the real gain. Gains that accrued to 30 June 2027 keep the old discount. Everything after that date is taxed under the new method. The minimum rate is the part investors keep missing, because it removes the old timing strategy of realising a gain in a low income year.

Now put the two systems side by side. A gain that is completely tax free in New Zealand is taxed in Australia at no less than thirty per cent of the real gain once the new rules commence, and because no New Zealand tax was paid there is no foreign income tax offset to claim against it. The absence of New Zealand tax does not reduce what you pay. It removes the credit you would otherwise have had.

Selling inside the two year bright-line window is not the answer either. New Zealand taxes that gain at marginal rates up to thirty-nine per cent and withholds at settlement, and only a proportionate share of the New Zealand tax ends up creditable in Australia.

There is a quieter point buried in the indexation change as well. Indexation applies to your cost base in Australian dollars. Movement in the exchange rate between purchase and sale is therefore built into the gain the Australian Taxation Office assesses, whatever the property itself did in New Zealand dollars.

The change that explains why this pitch exists at all

The second reform explains the timing of every new build approach landing in Australian inboxes this year.

From 1 July 2027, negative gearing on residential property is limited to new builds. Net rental losses on everything else are quarantined, deductible only against income from other residential property including a later capital gain, and carried forward where they cannot be used. Property held at 7.30pm on 12 May 2026 is grandfathered indefinitely. Anything acquired after that announcement can be negatively geared until 1 July 2027 and not beyond it.

When a deduction survives on one category of stock and disappears on the rest, the marketing follows the deduction. That is not a criticism of the policy. It is simply what happens, and it is why the volume of new build product being pushed at investors has lifted the way it has this year. A tax rule that makes a category easier to sell tells you nothing whatsoever about whether an individual property inside that category is any good.

For the New Zealand version there is a further wrinkle worth putting to your accountant directly. Technical commentary on the new rules reads the new build exception as applying to Australian residential property and excluding dwellings located outside Australia. If that reading holds, an offshore new build collects the worst of both systems. The loss is ring-fenced inside New Zealand under their rules, then quarantined again in Australia under ours. That is the difference between a deduction you use this year and a loss you carry forward with nothing to apply it against.

The interest deductibility claim in the pitch thins out on the same logic. Full deductibility was restored in New Zealand from 1 April 2025, which is true. Australia has allowed it the whole time, so the restoration adds nothing to an Australian return, and New Zealand ring-fences residential rental losses regardless.

Only the first claim survives the trip home intact. New Zealand genuinely has no stamp duty and no land tax, and transaction costs run to a few thousand dollars against twenty-five to forty thousand in duty on the equivalent Australian purchase. That is a real structural advantage and I will not pretend otherwise. It is also a one-off saving at entry, set against holding costs and an exit that run for the life of the investment.

All of this is general information rather than tax advice. Anyone contemplating an offshore purchase needs their own accountant across both jurisdictions before signing anything. What I want investors to take from it is narrower and more portable. An incentive that belongs to a jurisdiction is not the same thing as an incentive that belongs to you.

Now look at what is actually being sold

Strip the tax framing away and you have a new-build townhouse in Christchurch from $599,000. The real question is what that asset does.

Christchurch is the strongest region in New Zealand right now, and I want to be fair about that. Canterbury has reached record highs while Auckland sits around twenty-two per cent below its 2021 peak and Wellington around twenty-six per cent below. Population growth in Canterbury has led the country, the stadium at Te Kaha opened in March, the northern motorway works run to the end of the decade, and the affordability gap against Auckland is real.

The catch is that the reason Christchurch holds up is the reason it does not run. The city is flat, land is abundant and consenting is fast, so supply answers demand almost immediately. That caps growth in good times and cushions falls in bad ones. Over the twenty years to June 2026 Christchurch averaged about 4.4 per cent capital growth a year. Strong fundamentals do not produce capital growth in a market that can build its way out of demand inside eighteen months.

And the segment being marketed is the weakest part of it. Seventy-nine per cent of Christchurch consents in March 2026 were multi-unit, and one in four homes in the city is now a townhouse or terrace. Canterbury consented 8,647 dwellings in the year to June 2026, up thirty-three per cent and the strongest growth of any region, into national net migration of around 24,000.

The resale data is where it stops being theoretical. Cotality's Pain and Gain analysis for the March 2026 quarter found eighteen per cent of New Zealand townhouses reselling below their purchase price at a median loss of $49,500, against eleven per cent for standalone houses. Townhouses average 120 days on market against 96. Christchurch agents interviewed by OneRoof described appraising townhouses bought two years ago at $800,000 that would now struggle to reach $600,000, and pointed out that listing counts understate the position, because a developer holding a block of six will list one.

That last detail is the one I would underline. What advisors across our network test for in Australian estates is exactly this cluster problem. When dozens of near-identical dwellings land in the same street, every future resale is valued against the others, and the seller competes with the developer's remaining stock and with every other investor holding the same floor plan. Your exit gets priced by your neighbours.

The risks that never make the pitch

Run the numbers on a $650,000 Christchurch townhouse let at $600 a week and the gross yield is about 4.8 per cent, which reads respectably. Operating costs then take thirty-seven to thirty-eight per cent of gross rent, heavier than comparable Australian stock, driven by council rates rising six to eight per cent a year and by seismic insurance loadings. Net yield lands near 2.8 per cent. On sixty-five per cent lending the position runs at a pre-tax shortfall of roughly NZ$3,000 a year before cross-border accounting fees.

A one percentage point move in the interest rate adds more than that entire shortfall, and the direction has turned. The Reserve Bank of New Zealand lifted the Official Cash Rate to 2.50 per cent on 8 July 2026, its first increase in more than three years, and signalled further rises are likely. BNZ's chief economist expects floating mortgage rates above 6.5 per cent by the end of this year and near 7 per cent in the first half of 2027. New Zealand borrowers typically fix for one to two years, so the exposure is repeated rollover risk rather than gradual drift.

Currency sits on top of all of it. The Australian dollar has been trading near the top of its ten year range against the New Zealand dollar, which helps on entry and hurts on the way home. A ten per cent currency move is larger than the entire net yield on the asset, and it is a return driver the investor does not control.

Then there is the five per cent deposit, presented as a benefit. Ten per cent is the New Zealand norm. A smaller deposit widens the developer's buyer pool and reduces the pre-sale security it needs to show its financier. That is a fact about the developer's funding position, not a favour to the purchaser. What actually protects a buyer is whether the deposit is held by the vendor's solicitor as stakeholder until settlement, and only the sale and purchase agreement establishes that.

The valuation line deserves the same treatment. A registered valuation commissioned by the vendor is not an independent valuation commissioned by the buyer's lender at settlement, and banks lend on the lower of price or valuation. With pre-approvals lasting three to six months against build programmes of twelve or more, settlement risk on the valuation is the largest single financial exposure in any off-the-plan contract, and it is at its worst in an oversupplied segment.

Finally, and nobody raises this one, an Australian buying in New Zealand has no recourse to Australian consumer law, no ASIC oversight and no access to the Australian Financial Complaints Authority. Under the Real Estate Agents Act 2008 a New Zealand developer selling its own stock direct is exempt from agent licensing, so the code of conduct and complaints pathway that would apply to a licensed agent do not apply either. That is lawful and common. It also means every protection the buyer has comes from the New Zealand solicitor they engage and the contract that solicitor negotiates.

This is not a New Zealand problem

None of this makes New Zealand a bad market. It is a legitimate market, genuinely open to Australian citizens, with the lowest entry costs in the region, and plenty of people will do well there.

The problem is the reasoning being offered, and the identical pattern turns up here every week. Depreciation schedules carrying new builds that would not sell on their merits. Land tax changes in one state used to push stock in another. Super borrowing rules turned into urgency. And now a negative gearing carve-out for new builds, which will be used to sell a great many new builds that were never worth buying. In every case a tax position is doing the work that fundamentals should be doing.

Tax incentives are not a reason to overlook a poor asset, and no amount of favourable tax treatment will rescue an asset the next buyer does not want.

Ask what they are really selling

The habit worth building is separating the claim from the conclusion. When something arrives unsolicited, work through it in order. Is each claim true. Does it still apply to me, in my jurisdiction, in my circumstances, under the rules as they will be rather than as they were. And if I remove every incentive from the pitch, does the asset stand up on rent, on demand, on supply and on the depth of the buyer market I will one day need to sell into.

Then ask what the person in front of you is actually selling, and who pays them. A developer selling its own stock is not offering research. It is offering inventory. That is a legitimate business, but it is not advice and should never be mistaken for it.

Every investor's position is different, and the right market, structure and timing depend on circumstances no marketing pack can know. This is about making informed decisions rather than being carried along by a well-written summary.

The most dangerous pitch is not the one that lies to you. It is the one that tells you exactly what you were hoping to hear. Do not let yourself be drawn in by what you want to hear.
