If you're renting in New Zealand, both working steadily and trying to save a first-home deposit, it's understandable to feel that house prices and the deposit you need keep moving further away. The important question for the 2026 general election isn't just which party promises cheaper housing. It's who wants to change the tax advantages of owning investment property, who would tax capital gains, and whether those changes might make it easier for first-home buyers to compete.

There are two different issues to weigh up:

• Saving your deposit: Your take-home pay, rent, savings returns and the price of homes you can afford all matter.
• Competing for a home: Tax rules can affect the after-tax returns landlords receive, and therefore potentially affect investors' willingness to buy property, the supply of rentals and the prices first-home buyers face.

A policy can help in one way and hurt in another. For example, a tax change might make an investment property less attractive to a landlord, but it could also affect rents or the number of homes available to rent. The details matter.

1. Which parties propose property or capital-gains tax changes?

The following reflects published policy as of October 2026. The election is scheduled for 7 November, so these are campaign proposals, not enacted changes. Tax Tips: 2026 General ElectionSummary of 2026 election tax policiesElection 2026: What could change under each Party’s tax policy?

Labour

Targeted capital gains tax

Labour proposes a 28% tax on gains from residential investment and commercial property, applying to gains arising from 1 July 2027. The family home and farms would be excluded, as would shares and KiwiSaver. Labour has also said it would retain the current rules allowing landlords to deduct mortgage interest from rental income. Revenue from the proposed tax would be earmarked for health. Tax Tips: 2026 General ElectionLabour rules out interest deductibility changes for landlords

What it could mean for you: If the policy reduced the after-tax appeal of property speculation or investment relative to other assets, it might reduce some investor demand for existing homes. That could help first-home buyers compete, but the size of any price effect is uncertain.

Green Party

Changes to landlord tax rules and wealth

Rather than a new general capital gains tax, the Greens propose restoring a 10-year bright-line period for residential property and removing landlords' ability to deduct mortgage interest. They also propose an annual 2.5% wealth tax on individual net assets above $10 million, excluding the family home, and a 33% tax on gifts and inheritances above $1 million, with exemptions. Tax Tips: 2026 General ElectionElection 2026: What could change under each Party’s tax policy?Election tax policies, part one | Tax Alert - July 2026

What it could mean for you: Less favourable tax treatment could discourage some investors from buying existing homes, potentially easing competition. However, landlords could respond by raising rents where the market permits, selling properties or changing their investment decisions. The wealth and inheritance taxes are unlikely to apply directly to a typical first-home buyer.

Te Pāti Māori

Wealth and property taxes

Its tax package proposes a progressive wealth tax starting above $2 million in net assets, a 33% land-banking tax, a 2% vacant-house tax and a 5% stamp duty on residential sales. It proposes exempting first-home buyers purchasing homes below $1 million from stamp duty. Tax Tips: 2026 General ElectionElection 2026: What could change under each Party’s tax policy?

What it could mean for you: Taxes on land banking and vacant houses are intended to encourage land and housing to be used rather than held idle. A first-home-buyer stamp-duty exemption, if implemented as proposed, could directly reduce your purchase costs. The broader effect on prices and the supply of homes is less certain.

Opportunity (formerly TOP)

Annual land value tax

Opportunity proposes an annual tax of 1.75% of urban land value and 0.5% of rural land value. The tax applies to land rather than buildings, with some exemptions and deferral provisions. The party links its wider tax reform to a tax-free Citizen's Income. Tax Tips: 2026 General ElectionElection 2026: What could change under each Party’s tax policy?

What it could mean for you: Because the tax applies to land value rather than the building, it could encourage owners to use valuable land more productively and could influence land prices. But it could also raise the ongoing cost of owning a home, including for owner-occupiers. Its impact would depend on how much of the tax is reflected in land prices and how the other parts of the tax package affect your household.

National

National is campaigning against new taxes and is not proposing a new general capital gains tax or a new property tax. It has restored full mortgage-interest deductibility for residential landlords and emphasises housing supply, planning reform and faster consents. Summary of 2026 election tax policiesNZ election 2026: what it means for landlords, says economist Brad Olsen

What it could mean for you: This approach aims to improve affordability through more housing construction and investment rather than new taxes on property owners. More supply can help affordability over time, but the pace of building and population growth matters.

ACT

ACT opposes capital gains and wealth taxes and favours lower or flatter income taxes, spending restraint and a stronger focus on investment. Summary of 2026 election tax policiesElection 2026: What could change under each Party’s tax policy?

What it could mean for you: There would be no new CGT under ACT's stated approach. Its case for affordability rests more on economic growth, investment and housing supply than on changing the tax treatment of property investors.

New Zealand First

New Zealand First has not put forward a comparable comprehensive property-tax reform package. Its tax announcements include a proposed lower company tax rate for smaller businesses; it does not appear to support a new capital gains or wealth tax. Summary of 2026 election tax policiesElection 2026: Will parties’ tax policies support public health and equity?

What it could mean for you: Its announced tax measures offer less direct change to the tax treatment of residential property than the Labour, Greens, Te Pāti Māori or Opportunity packages.

2. How could these policies affect your deposit?

Here is the practical comparison for a couple who rent, have steady employment and are saving to buy their first home.

Policy approach	Possible benefit for you	Main uncertainty or trade-off
Capital gains tax (Labour)	Could reduce some investors' willingness to bid for existing homes	May have a modest or delayed effect on prices
Tighter landlord tax rules (Greens)	Could reduce investor demand for existing properties	Could affect rents, rental supply and investment in new homes
Vacant-home and land-banking taxes (Te Pāti Māori)	Could encourage more productive use of existing land and homes	Effects depend on enforcement and whether owners actually sell or develop
First-home stamp-duty exemption (Te Pāti Māori)	Could reduce your upfront buying costs directly	Only helps if you meet the proposed eligibility rules and the policy is enacted
Land value tax (Opportunity)	Could encourage more efficient use of land and potentially change land prices	Creates an ongoing ownership cost and could affect household budgets
No new property taxes (National and ACT)	Avoids introducing these additional taxes	Affordability depends more on supply, income growth and other housing policies

These are potential effects, not guaranteed outcomes. The parties' policies and independent tax-policy summaries are available through Policy.nz's 2026 election guide and PwC's tax-policy comparison. Policies for Party vote - NZ Election 2026Tax Tips: 2026 General Election

3. The key distinction: cheaper houses versus a bigger deposit

Suppose your household is saving towards a home priced at $800,000. A 20% deposit would be $160,000.

Illustrative example — not a forecast of prices

Target home price

$800,000

20% deposit target

$160,000

If the same home became 5% cheaper, at $760,000, a 20% deposit would fall to $152,000 — a reduction of $8,000.

That would be useful progress. But if your rent rises, your savings earn less than expected, or prices rise elsewhere, some of that benefit could disappear.

This is why it's worth looking beyond the headline tax rate. A policy that reduces the price of a home helps you in a different way from one that gives you extra disposable income to save each month.

Also, don't assume a capital gains tax means every house becomes cheaper. The impact depends on how investors respond, how much new housing is built, interest rates, credit availability and the wider economy.

4. What I would focus on before casting your vote

For your situation, I'd compare parties on four questions:

• Will it make the homes we want more affordable? Look for credible measures to increase housing supply and reduce competition for existing homes, not just promises of lower prices.
• Will it help us save faster? Compare proposed income-tax changes and cost-of-living measures with the likely effect on your household's take-home pay and rent.
• Will it lower the upfront barrier? Deposit assistance or a first-home stamp-duty exemption can be more immediately relevant than a tax that affects property investors over several years.
• Is the policy likely to be implemented? Under MMP, the final policy depends on coalition negotiations and legislation. A party's campaign proposal isn't a guarantee of a change in the rules. Summary of 2026 election tax policiesElection 2026: What could change under each Party’s tax policy?

My overall assessment: Labour and the Greens offer the clearest alternatives to the current tax treatment of residential property investment; Te Pāti Māori proposes more direct property taxes alongside a first-home-buyer stamp-duty exemption; and Opportunity proposes a broader shift towards taxing land. National and ACT favour avoiding new property and capital-gains taxes. New Zealand First has announced fewer direct changes in this area.

None of these positions, on its own, guarantees that you'll buy sooner. The best fit depends on whether your biggest obstacle is the deposit you can save, the prices of suitable homes, or the ongoing cost of a mortgage.

For a useful next step, compare each party's detailed housing affordability, rental and income-tax policies alongside its property-tax proposals, rather than making your decision on capital gains tax alone.
