Every question, every answer, every source

If you’re weighing the 2026 election mainly through the lens of “can my partner and I get from renting to owning without the goalposts moving again?”, the most useful distinction is between policies that change who is bidding for existing homes and policies that change how many homes can be built.

The big picture

There are three main policy levers:

1. Investor demand: make owning additional properties more or less attractive through capital-gains, interest-deductibility and other tax rules.
2. Land supply and planning: make it easier and more profitable to turn land into housing.
3. Construction and infrastructure: make actual building cheaper/faster and make sure councils can provide roads, water and other infrastructure.

For first-home buyers, those mechanisms can pull in different directions. Reducing investor demand can put downward pressure on prices relatively quickly, while building substantially more homes is the longer-term route to making housing less scarce. Deposit assistance can help an individual buyer, but if it increases purchasing power without increasing supply, some of that benefit can be capitalised into higher prices.

There is unusually good New Zealand evidence for the supply side: research on Auckland's large 2016 zoning reform finds that allowing more development increased housing supply and reduced rents. Dispelling myths: Reviewing the evidence on zoning reforms in Auckland | Motu Treasury, the Ministry of Housing and Urban Development and the Reserve Bank have also found evidence that restrictions on Auckland's urban land supply increased land prices.

How the major positions differ

Party	Investors	Land use / planning	Building more homes	Possible first-home effect
National	Keep current pro-investor tax settings; no new taxes	Strongly expand developable land and require competitive urban land markets	Faster consenting, infrastructure-financing reforms	More supply could restrain prices over time; 5% deposit policy helps access but could add demand
Labour	28% CGT on gains from investment residential/commercial property, excluding family homes	Less emphasis than National/ACT on a sweeping land-supply change	More Kāinga Ora and community/social housing	Investor demand could fall, putting downward pressure on prices; public building adds supply, but effect on private prices is less direct
Greens	Reverse landlord tax cuts and bright-line changes; much stronger anti-speculation approach	Housing treated primarily as a necessity rather than investment	Tens of thousands of public homes + community/council housing	Stronger downward demand pressure from investors plus more non-market supply; effects depend heavily on implementation
ACT	Keep/reinforce investor-friendly settings, including opposition to landlord tax restrictions	Very strong deregulation: easier development, consenting and infrastructure provision	Private-sector-led construction, infrastructure incentives, building-material reform	Relies heavily on a much larger housing supply response to bring down costs
Opportunity	Tax land rather than labour/property transactions; use LVT to discourage land banking and large portfolios	LVT creates an incentive to develop valuable urban land	Government/CHP finance and GST refunds for qualifying new builds	Potentially substantial downward pressure on land values, but a major change to the tax system
NZ First	Its housing position is less developed in the material I could verify than the parties above	—	—	I wouldn't infer a price effect without a specific current policy

National: attack the shortage of developable land

National's current policy is particularly focused on land markets and supply. Its proposed planning system would require councils to maintain urban land markets that respond to demand, with an independent Urban Land Market Officer able to identify councils restricting supply. National also wants private plan changes to be easier. Achieving competitive urban land markets in new system | National Party

It is also expanding infrastructure-financing mechanisms so that infrastructure needed for developments can be financed through levies on benefiting properties rather than councils having to fund everything upfront. Better tools to fund and finance new infrastructure | National Party

For someone saving a deposit, there is a second, quite different National policy: widening the First Home Loan income cap to $300,000, allowing qualifying first-home buyers to use a 5% rather than 20% deposit. National is backing first home buyers | National Party

Price mechanism: the supply reforms could reduce land scarcity and eventually put downward pressure on house prices. The 5% deposit policy does the opposite on the demand side: it gives some buyers more purchasing capacity. If there aren't enough additional houses, that extra purchasing power can partly show up in prices.

So National is effectively combining more purchasing power for first-home buyers with a major attempt to increase supply.

Labour: reduce the investment advantage and build public housing

Labour's most significant investor proposal is a 28% capital-gains tax on gains made after 1 July 2027 on investment residential and commercial property, excluding the family home, farms and several other asset classes. Labour explicitly says the purpose is partly to shift investment away from housing and reduce the number of investors bidding against first-home buyers.

On construction, Labour proposes $2.9 billion of capital for Kāinga Ora to resume building state houses, plus $745 million of operating funding. It also proposes a $950 million Crown guarantee for community-housing finance, which Labour says would reduce borrowing costs and allow providers to build more homes. Start Work Now - NZ Labour

Price mechanism: fewer investor buyers can mean less competition for existing homes, while additional public/community housing increases total housing stock. The important caveat is that social housing isn't necessarily a substitute for the private homes you would be looking to buy, so the effect on your eventual purchase price is less direct than a broad increase in private construction.

Labour's stronger KiwiSaver settings could also improve deposit accumulation over time, although that's primarily an effect on your ability to buy rather than on the underlying price of a house. Strengthening KiwiSaver for the Future - NZ Labour

Greens: the strongest shift away from housing as an investment

The Greens' housing policy goes further on investor taxation. They propose reversing the landlord tax cuts and changes to the bright-line test introduced under the current government, alongside building tens of thousands of public homes and supporting community and council housing. Greens announce plan to end homelessness & fix housing crisis - Green Party of Aotearoa New Zealand

They also propose rent controls and stronger renter protections, which are much more consequential for you while you're saving than for the eventual purchase price.

Price mechanism: the intended effect is to make investment property less attractive and shift housing toward owner-occupation. That could reduce investor demand for existing homes. The public-housing programme could also increase total housing supply, although again its direct effect on the price of a privately sold first home is uncertain.

One thing to watch is that policies affecting landlords can have mixed effects on renters: if landlords exit or reduce investment in rental property faster than other providers replace those homes, the rental market could tighten. That's separate from the question of what happens to purchase prices.

ACT: let the market build its way out of the shortage

ACT's approach is closest to a supply-and-deregulation strategy. It has argued that Auckland has enough land zoned for housing and that the bottlenecks are infrastructure and consenting; its proposals include easier development, alternative infrastructure financing and wider acceptance of building materials approved by comparable regulators. ACT New Zealand

ACT has also consistently opposed policies that make residential investment less attractive, arguing that landlords and investors should not be treated as the housing problem. ACT New Zealand

Price mechanism: ACT's theory is essentially that if development becomes sufficiently easy and profitable, developers will build enough homes that scarcity rents and land prices fall. That's consistent with the Auckland evidence that large-scale zoning reform can increase supply and reduce housing costs. Dispelling myths: Reviewing the evidence on zoning reforms in Auckland | Motu

The critical question isn't simply “does ACT allow more building?” but whether the reforms actually produce a large enough construction response. Planning reform on paper doesn't automatically translate into completed houses.

Opportunity: tax the land rather than the buildings

Opportunity is a rather different proposition. Its 1.75% annual Land Value Tax would be charged on land value, with the stated aim of discouraging land banking and large property portfolios and shifting investment away from property. It would be used alongside a Citizen's Income. Tax Reset Calculator 2026 - Opportunity Party

It also proposes GST refunds to councils for qualifying new environmentally efficient builds, government-backed finance for affordable/social housing, and allowing developers to defer the land tax while development is occurring. Affordable Housing - The Opportunity Party

Price mechanism: because the tax attaches to the underlying land, rather than simply taxing transactions or building improvements, it could reduce the amount buyers are willing to pay for land. Opportunity explicitly presents this as a way of making housing more affordable. Tax Reset Calculator 2026 - Opportunity Party

But this would be a very large change to the tax system, so its effects on existing homeowners, landlords, land prices, development and rents would be considerably more complex than a conventional investor tax.

What matters most for your deposit problem?

There's a useful distinction between “helping us buy a house” and “making houses cheaper.”

Suppose you and your partner need another $80,000 to reach a deposit. A policy that lets you borrow with a smaller deposit may solve the first problem. But if thousands of other buyers simultaneously gain purchasing power while the number of houses doesn't change, sellers can capture some of that additional purchasing power through higher prices.

By contrast, policies that make it possible to build many more houses in the places people actually want to live attack the scarcity underneath the price.

The Auckland experience is important here. The 2016 Unitary Plan substantially increased development capacity across the city, and research finds that this translated into more construction and lower rents. Dispelling myths: Reviewing the evidence on zoning reforms in Auckland | Motu Treasury's work also finds that constrained land supply had materially increased the price of urban land. Analysis of availability of land supply in Auckland | The Treasury New Zealand

Investor policy matters too. The Reserve Bank found that earlier restrictions on interest deductibility and the bright-line test reduced investor activity; it reported investment-property lending falling from about 26% to 17% of new mortgage lending after those measures, although that was also affected by other factors. House prices above sustainable levels - Reserve Bank of New Zealand - Te Pūtea Matua More recently, the Reserve Bank says restored interest deductibility has provided some support to investor demand. Financial Stability Report November 2025 - Reserve Bank of New Zealand - Te Pūtea Matua

So the two sides of the debate aren't really contradictory:

Less investor demand → fewer competing bidders → downward pressure on existing-home prices.

More housing supply → less scarcity → downward pressure on land/rents/prices over time.

The question is which combination is large enough, and fast enough, to matter to you.

One thing I'd particularly watch as a renter saving a deposit

I'd be wary of judging policies solely by whether they advertise a particular dollar amount of help for first-home buyers.

For your situation, I'd look at four questions:

• Does it increase the number of homes that can actually be built where jobs and transport are?
• Does it make development financially viable, including infrastructure?
• Does it reduce or increase the incentive for investors to compete for existing houses?
• Does it increase your purchasing power without increasing supply at the same time?

The last question is especially important. A $50,000 improvement in your ability to buy isn't necessarily equivalent to a $50,000 reduction in the price of the house you're trying to buy.

And because you're in the position of renting while accumulating a deposit, there's a fifth question: what happens to your rent while you're waiting? A policy can improve eventual purchase affordability but make the intervening rental market more or less comfortable.

I would therefore separate the parties' proposals into “reduce the price of housing”, “increase our ability to buy housing”, and “make renting easier while we wait.” Those are three different objectives, and the 2026 parties have quite different mixes of them. Affordable homes for all

If you want to take this one step further, I can also make you a neutral “first-home-buyer scorecard” covering National, Labour, Greens, ACT, NZ First and Opportunity on house prices, deposit saving, rent, mortgage access and housing supply, without telling you which party to vote for.
