Taken separately, the tax policies released by Labour, the Greens and Te Pāti Māori look quite different. Put them alongside each other, however, and something interesting emerges: there is considerably more philosophical alignment than contradiction — but there would also be some very difficult coalition negotiations over how many taxes could reasonably operate at the same time.
All three start from broadly the same proposition: New Zealand relies too heavily on taxing wages and consumption, while accumulated wealth, property gains and some forms of corporate income receive comparatively favourable treatment. Where they differ is how aggressively they would rebalance that system, which forms of wealth they would tax, and how far they would cut income tax at the bottom.
The three approaches
Labour has chosen the narrowest approach.
Its centrepiece is a 28 percent capital gains tax on profits from residential investment and commercial property, excluding the family home and farms. It would apply only to gains accruing after 1 July 2027 and only when the property is sold. KiwiSaver, shares, businesses, inheritances and gifts are excluded. Labour says all of the revenue would be ring-fenced for health, including three free GP visits each year.
The Greens go considerably further. Their plan creates a $10,000 tax-free threshold, increases income tax for people earning above $160,000, imposes a 2.5 percent wealth tax on net assets above $10 million, excluding the family home, and introduces a tax on very large inheritances and gifts above $1 million, with exemptions including family homes and family farms.
The Greens would also raise the company tax rate to 33 percent for the largest 0.7 percent of corporations, introduce a 0.06 percent bank levy, enforce a 5 percent withholding tax on profits sent offshore by big technology companies, and reverse the Government’s landlord tax changes. The party says 96 percent of people would receive an income-tax cut.
Then there is Te Pāti Māori, whose newly announced Kiwi Tax Plan is potentially the most redistributive of the three.
Its income-tax proposal makes the first $30,000 tax-free, followed by rates of 15 percent from $30,001–$60,000, 33 percent from $60,001–$90,000, 39 percent from $90,001–$180,000, 42 percent from $180,001–$300,000 and 48 percent above $300,000. The party says 97 percent of taxpayers would pay less income tax and estimates around 4.2 million people would receive an average benefit of roughly $4,000 annually.
Te Pāti Māori would finance that partly through a wealth tax beginning at 1.5 percent above $2 million, increasing to 2 percent above $5 million and 2.5 percent above $10 million. Its package also includes returning company tax to 33 percent, a 5 percent international profit-transfer tax, a 33 percent land-banking tax, a 2 percent vacant-house tax and a new 5 percent stamp duty on residential property sales, with an exemption for first-home buyers purchasing below $1 million.
It has also moved away from simply removing GST from food and instead proposes a targeted kai credit for people earning $60,000 or less, described as worth up to about eight weeks of food each year.
Where they fit together surprisingly well
There are four areas where forming a common tax platform would be relatively straightforward.
First is tax relief for ordinary incomes.
The Greens want the first $10,000 tax-free. Te Pāti Māori wants $30,000 tax-free.
That isn’t an ideological disagreement. It’s essentially an argument about how large the tax-free threshold should be and how to pay for it.
A coalition could therefore negotiate a number somewhere between $10,000 and $30,000, or phase a $30,000 threshold in over several Budgets.
That could become one of the most politically powerful parts of a Labour-Green-Te Pāti Māori tax agreement because people would see the benefit directly in their pay packets.
Labour’s published CGT policy doesn’t propose such a threshold, so Labour would have to accept a substantial expansion of income-tax relief for this to happen.
Second: taxing very high wealth
The Greens and Te Pāti Māori already agree on the principle of an annual wealth tax.
Their disagreement is primarily over where it begins.
The Greens propose 2.5 percent above $10 million, with the family home exempt.
Te Pāti Māori starts much lower — 1.5 percent on net wealth above $2 million, rising through higher bands.
That is a substantial negotiating gap, but it is still a negotiation over thresholds rather than the existence of a wealth tax itself.
A compromise could theoretically set the threshold at, say, $5 million or $10 million while adopting progressively higher rates for extremely large fortunes.
Labour would be the obstacle here, because its announced tax strategy deliberately concentrates on realised property gains rather than an annual wealth tax.
Third: corporations and offshore profits
Here the Greens and Te Pāti Māori are remarkably close.
Both want significantly more revenue collected from large companies and offshore profit flows.
The Greens propose a 33 percent company rate for the largest 0.7 percent of corporations and a 5 percent withholding tax on profits sent offshore by big tech.
Te Pāti Māori proposes restoring the company rate to 33 percent more broadly and imposing a 5 percent international profit-transfer tax.
A coalition negotiation could therefore readily produce a 33 percent large-company tax rate plus stronger rules around offshore profit transfers.
The argument would probably be over which companies face 33 percent rather than whether larger corporations should contribute more.
The big problem: property could be taxed three different ways
This is where attempting simply to bolt all three manifestos together becomes problematic.
Under Labour, an investment property’s capital gain could be taxed at 28 percent when sold.
Under Te Pāti Māori, the property transaction itself could also attract a 5 percent stamp duty.
And depending on the owner’s overall wealth, the property could contribute to an annual wealth-tax liability.
Meanwhile, the Greens want landlord tax concessions reversed and changes to the bright-line regime.
Those policies can technically coexist.
But that doesn’t necessarily mean they should all coexist unchanged.
Imagine an investor with substantial assets selling a second property.
That person could potentially have faced an annual wealth tax while holding the asset, lose interest deductibility under Green policy settings, face Labour’s CGT on the eventual gain and encounter Te Pāti Māori’s stamp-duty regime when the property changes hands.
The danger for a coalition would be creating overlapping taxes aimed at essentially the same economic behaviour.
The better solution would be tax-system design rather than policy accumulation.
The most logical coalition package
If the objective were to take the central ideas from all three parties rather than simply stack every tax on top of every other tax, a coherent compromise could look something like this:
| Area | Possible combined approach |
| Income tax | Introduce a substantial tax-free threshold |
| Low/middle incomes | Deliver the largest reductions here |
| High incomes | Add higher rates for very high earners |
| Property | Adopt Labour’s 28% CGT rather than multiple overlapping property taxes |
| Wealth | Negotiate a high threshold for an annual wealth tax |
| Family home | Continue broad protection/exemption |
| Corporates | Higher company rate targeted at very large businesses |
| Multinationals | Stronger taxation of offshore profit transfers |
| Banks | Consider Green bank levy |
| Empty property/land banking | Targeted measures rather than taxing ordinary homeowners |
| Inheritance | Probably one of the hardest coalition negotiations |
| Kai | Targeted assistance for lower-income households |
| Revenue | Health, housing, education and whānau support |
That would create something much closer to a tax switch than simply a tax increase.
The political proposition becomes:
tax wages less at the bottom and middle, while taxing accumulated wealth, property gains, extremely high incomes and some corporate profits more heavily.
And that is the common thread running through the Green and Te Pāti Māori plans, while Labour’s CGT moves partially in the same direction.
What could it mean for whānau Māori?
This is where combining the policies becomes particularly interesting.
Māori households generally hold substantially less accumulated wealth than the wealthiest households targeted by the Green and Te Pāti Māori proposals. At the same time, many Māori households derive most of their income from wages.
Consequently, the architecture of a large tax-free threshold combined with taxes concentrated on substantial wealth could shift more disposable income towards many working whānau.
But that conclusion needs an important qualification: the three parties have not published a jointly modelled package, so we cannot simply add each party’s claimed revenue and household savings together.
Tax policies interact.
A $30,000 tax-free threshold changes the revenue generated by every other income-tax bracket. A CGT changes investment behaviour. A wealth tax can change asset structures. Corporate taxes can affect investment decisions and distributions. Stamp duties can affect property transactions.
So claims that combining the three packages would automatically produce a particular multibillion-dollar surplus would be premature.
There is also a fundamental Labour problem
The economics may actually be easier than the politics.
Labour has deliberately chosen a relatively narrow CGT.
The Greens and Te Pāti Māori are effectively proposing structural tax reform.
That distinction matters.
Labour’s policy reflects: tax some property gains and use the money for healthcare.
The Greens’ argument is closer to: rebalance taxation away from ordinary incomes towards concentrated wealth and large corporations.
Te Pāti Māori goes further again: dramatically reduce income tax for most people and transfer a greater proportion of the tax burden onto high incomes, wealth, property transactions and corporate activity.
Those aren’t mutually exclusive ideas.
But they represent very different levels of ambition.
And Te Pāti Māori has now described transformational tax change as a bottom line for coalition negotiations, while reporting around Labour’s position indicates it has been unwilling to adopt the broader tax proposals of potential coalition partners.
That potentially makes tax one of the defining negotiations if the election produces a Parliament in which Labour requires both the Greens and Te Pāti Māori to govern.
The fascinating political possibility
There is nevertheless a potentially powerful compromise sitting underneath all three policies.
Labour gets its capital gains tax.
The Greens get a wealth tax and greater taxation of large corporations.
Te Pāti Māori gets a much larger tax-free threshold and greater redistribution towards low- and middle-income households.
In return, some of the overlapping proposals — particularly stamp duty, bright-line rules, wealth-tax treatment of property and Labour’s CGT — would need to be rationalised into a single coherent system.
Such an agreement would represent one of the biggest changes to New Zealand’s tax architecture in decades.
The real dividing line would no longer simply be higher taxes versus lower taxes.
It would be:
Who should New Zealand tax less — and who should it tax more?
That is ultimately where these three policies intersect.
Labour wants to tax property gains more.
The Greens want to tax extreme wealth and large corporations more while cutting income tax for most people.
Te Pāti Māori wants to go considerably further by making the first $30,000 earned tax-free, while transferring much more of the burden towards high incomes, accumulated wealth, property and corporate profits.
The unanswered question isn’t whether elements of the three plans could work together.
They could.
The much bigger question heading towards Election 2026 is how much of their individual tax agendas Labour, the Greens and Te Pāti Māori would be prepared to surrender in order to build one tax system they could all govern with.
And if the numbers on election night make all three necessary for a government, that may become one of the most consequential coalition negotiations of them all.
The other story here is economic credibility
There is another important conclusion emerging from comparing these policies, and it is one that risks being overlooked amid the inevitable political argument over wealth taxes, capital gains and tax cuts.
Look at the level of detail.
Whatever voters ultimately think of the policies themselves, the Greens and Te Pāti Māori have not simply arrived with slogans about taxing the wealthy. They have attempted to construct broader tax systems: setting thresholds, defining exemptions, changing income-tax brackets, identifying new revenue sources and explaining how additional revenue would be redistributed.
Te Pāti Māori’s package is particularly significant in this respect because it has accompanied its political proposition with costings and estimates of who gains, how many taxpayers would receive reductions and where the revenue required to fund those reductions would come from.
That doesn’t mean every assumption will survive scrutiny. Nor does it mean economists, businesses or other political parties will agree with the modelling. Tax policies of this scale should be stress-tested precisely because behavioural changes can alter the amount of revenue eventually collected.
But there is a difference between disagreeing with an economic policy and claiming there is no economic policy.
And that distinction matters in Election 2026.
Challenging an old political narrative
For decades there has been a recurring political narrative that parties of the centre-right are naturally better economic managers, while parties of the left are stronger on social policy but weaker when it comes to taxation, business and fiscal management.
The level of detail now being presented makes that much harder to simply assert without evidence.
Te Pāti Māori is attempting to demonstrate how a substantial reduction in income taxation could be financed.
The Greens have set out how they would redistribute the tax burden between ordinary incomes, very high wealth and larger corporations.
Labour has chosen a more conservative route through its proposed capital gains tax, including defining what would and would not be captured and earmarking the resulting revenue for health.
You can argue with all three.
Business can challenge the assumptions. Economists can debate behavioural responses. Political opponents can argue that particular taxes would discourage investment or raise less money than forecast.
But that is now an argument about competing economic models — not an absence of economic thinking.
And that is an important distinction.
Labour is still the missing part of the puzzle
There is an obvious qualification.
Labour is yet to release its complete election policy programme.
It would therefore be premature to describe what a Labour-Green-Te Pāti Māori fiscal programme would ultimately look like.
But based on what has been released so far, there is already considerable common ground.
All three are moving towards the proposition that the tax system should place less pressure on ordinary working households and derive more revenue from some combination of capital gains, accumulated wealth, very high incomes and corporate activity.
Their disagreement is predominantly about how far to go.
That is potentially much easier to negotiate than three parties beginning from fundamentally incompatible economic positions.
And business should pay attention to that
There is another reason this matters.
Investors and businesses don’t necessarily require governments to have the lowest possible tax rates. What they value enormously is certainty.
Businesses make investment decisions over years, not election cycles. They want to know what company tax is likely to be, how capital will be treated, whether investment-property rules are going to change repeatedly and whether a government has a credible fiscal framework.
Constantly changing the rules can itself impose costs.
That means one of the more interesting possibilities arising from these policies is that a Labour-Green-Te Pāti Māori negotiation could ultimately produce greater long-term certainty, provided the parties agree on one coherent system rather than simply stacking their individual taxes together.
For example, agreeing that a capital gains tax will replace some existing property-tax mechanisms would be considerably easier for investors to plan around than CGT, stamp duty, bright-line rules and other measures continually being switched on and off by successive governments.
The same principle applies to corporate taxation.
Whether the eventual company rate is 28 percent, 30 percent or 33 percent, business can price that into investment decisions.
What is much harder to price is policy instability.
That may be the bigger opportunity
This is why the common ground between these parties could become more important than their differences.
Imagine a coalition agreement that establishes a tax framework intended to last beyond a single parliamentary term:
lower taxation on low and middle incomes; a clearly defined treatment of capital gains; an agreed high-wealth regime; stable corporate taxation; strong rules around multinational profit shifting; targeted measures against land banking and speculation; and clearly identified spending priorities.
That would provide households with greater certainty about what they keep.
It would provide government with greater certainty about revenue.
And importantly, it could provide business and investors with greater certainty about the rules under which they are expected to operate.
That is fiscal policy rather than simply tax policy.
It also changes the election argument
The political debate therefore shouldn’t simply become:
“Who is introducing another tax?”
The better questions are:
What does the entire system raise? What does it cost? Who pays more? Who pays less? What economic behaviour might change? And does the package leave the Government with enough revenue to sustainably fund health, education, infrastructure and public services?
Those are the tests that should now be applied equally to every party.
And if Te Pāti Māori can produce costings for a major restructuring of personal taxation, it is entirely reasonable to expect National, ACT, New Zealand First, Labour and the Greens to subject their own promises to the same level of scrutiny.
That is where this election could become particularly interesting.
Because the emerging tax debate is beginning to undermine the simplistic proposition that the political right inherently understands economic management while the left inherently understands spending.
Economic credibility doesn’t come from where a party sits in Parliament.
It comes from whether the numbers add up.
And while Labour still has considerably more of its 2026 economic programme to reveal, what we can already see across Labour, the Greens and Te Pāti Māori is enough common ground to suggest that a negotiated tax and fiscal programme is entirely possible.
The real test would be whether they could turn three manifestos into one coherent, costed and durable economic programme — one that delivers redistribution for households while also giving businesses and investors the stability and certainty they need.
If they can do that, the argument heading into Election 2026 may no longer be about whether the left can manage the economy.
It may instead become a much more demanding question for every party:
Who has actually done the work?
