If your main concern is “will a government actually get the pipes, roads and public transport built without pushing the cost onto existing homeowners and renters?”, the parties are offering noticeably different answers.

One important caveat: the 2026 election is on 7 November 2026, so some policies are still being released. I’ve focused on the major parties with clearly published positions and on the funding mechanisms rather than trying to tell you who to vote for. Policy.nz

The short version

Party	How they propose to fund growth infrastructure	Who broadly pays?
National	Development levies, private finance, tolls/RUC, PPPs, central-government funding, incentives for councils	Increasingly new development/property benefiting from infrastructure, plus users/taxpayers
ACT	More user-pays funding, road-user charges, tolling and private-sector delivery; build ahead of growth	Road users/developers/users, with less emphasis on general taxation
Labour	More conventional Crown investment, funded within its capital allowances; transport funding through the NLTF	More heavily general government funding/taxation, with reprioritisation
Greens	Large public investment in public and sustainable transport, funded alongside a substantially more progressive tax system	More general taxation, particularly higher-wealth/high-income taxpayers and large corporations
NZ First	A proposed $100b New Zealand Future Fund for long-term infrastructure, plus requiring housing developments to have infrastructure funded before approval	Long-term investment fund/private capital plus public financing; developers must demonstrate infrastructure is covered

The really important distinction is that “who pays for infrastructure?” and “who finances it upfront?” are not necessarily the same thing.

National: “growth pays for growth”

National's current approach is probably the clearest example of trying to solve your particular problem through dedicated charges on development rather than asking existing ratepayers to finance everything upfront.

The government is replacing development contributions with a more flexible development levies system. Those levies are intended to recover the cost of growth-related infrastructure including water supply, wastewater, stormwater and transport. National Party

It has also changed the Infrastructure Funding and Financing Act so that private investors can finance infrastructure upfront and recover their money over time through levies on properties benefiting from it. The expanded system can cover transport infrastructure from NZTA and KiwiRail as well as water infrastructure. National Party

National is also proposing:

• a $400m Incentives for Growth Fund, rewarding councils for homes consented;
• greater use of tolls and toll concessions;
• road-user charges as the vehicle fleet transitions toward RUC;
• public-private partnerships;
• making it easier for developers or independent infrastructure providers to build enabling infrastructure themselves. The Treasury

For a first-home buyer, the upside: this is designed to prevent a situation where councils say “we can't afford the pipes, therefore we can't approve the subdivision.”

The catch: infrastructure costs don't disappear. Development levies ultimately become part of the economics of building a house. Developers can absorb them, pass them into land prices, or pass some of the cost into the price of the finished home. So “growth pays for growth” doesn't necessarily mean houses become cheaper.

ACT: push further toward user-pays

ACT is broadly aligned with the National government's infrastructure direction but places an even stronger emphasis on building ahead of growth and making users pay for infrastructure through charges.

Its transport policy says major growth corridors should trigger route protection, planning and eventually additional capacity as traffic rises. ACT also wants transport spending concentrated on core infrastructure and maintenance. ACT New Zealand

The broader ACT philosophy is that infrastructure should be funded by mechanisms such as road-user charges, tolls and development-related charges, rather than simply drawing more money from general taxation.

That makes ACT particularly relevant if your question is:

“Why should someone who already owns a house pay higher taxes/rates to provide infrastructure for a new subdivision?”

ACT's answer is essentially: the people who cause or benefit from the infrastructure should pay more of its cost.

The trade-off is that this can make development and transport more expensive at the point of use.

Labour: more emphasis on public investment

Labour's published 2026 fiscal plan commits to $12b of future capital allowances, with almost $8b currently unallocated after its announced commitments. It says infrastructure investment will be part of that capital programme and that the overall plan returns the operating balance to surplus in 2028/29. Labour Party

On transport specifically, Labour would keep investing through the National Land Transport Fund, while reprioritising 1% of it to fund its proposed public-transport fare cap. Labour Party

So Labour's approach is less centred on the National/ACT idea that each development should carry much more of its own infrastructure cost, and more on government making strategic infrastructure investment as part of the wider public budget.

For someone saving a deposit, that matters because there's a potential trade-off:

• More Crown funding can reduce the infrastructure charges confronting individual developments.
• But it means infrastructure competes with health, education, welfare and other government spending—and ultimately has to be paid for through taxes, borrowing or future spending restraint.

Labour is also explicitly promising to keep public transport investment going rather than shifting the transport system predominantly toward roads. Labour Party

Greens: much more publicly funded infrastructure

The Greens take the strongest position toward large-scale public investment in transport, particularly public and sustainable transport.

Their 2026 manifesto calls for investment in modern, sustainable and affordable transport, while their recent policies include intercity passenger rail and major rail investment. Green Party of Aotearoa New Zealand

Their funding model is also fundamentally different. The Greens propose:

• a 2.5% annual tax on net assets above $10m, excluding family homes;
• higher corporate tax for the largest corporations;
• a bank levy;
• other changes to taxing high-income/high-wealth people and corporations.

They estimate these tax changes would generate around $5.15b of additional net revenue in 2027/28, rising to $5.73b by 2030/31. Green Party of Aotearoa New Zealand

So their answer to infrastructure funding is much closer to:

“New Zealand has an infrastructure deficit; fund the investment collectively through a more progressive tax system.”

That can mean less reliance on direct charges attached to individual housing developments, but it also means a greater role for taxpayers and government borrowing/investment decisions.

NZ First: a very large long-term investment fund

NZ First has proposed creating a New Zealand Future Fund of up to $100 billion, specifically to invest in multi-decade infrastructure. New Zealand First

That's a much bigger and more unusual proposition than simply allocating infrastructure money through the annual Budget.

NZ First is also very explicit about the “don't approve housing first and worry about infrastructure later” problem. Its October 2026 policy would require fast-tracked housing developments to demonstrate that required roads, water, wastewater and other infrastructure exists, is funded and can be delivered when needed. New Zealand First

In other words, NZ First is particularly focused on preventing existing communities from effectively subsidising inadequately serviced new developments.

What this means for your deposit

I'd pay particular attention to three questions, rather than simply asking which party promises to spend the most.

1. Who ultimately pays for the pipes?

This is the biggest difference.

National/ACT increasingly favour development levies and user-pays mechanisms. Labour and the Greens put relatively more weight on central-government investment funded through the broader tax-and-Budget system. NZ First proposes a very large dedicated investment vehicle.

And there's a subtle but important point: developers paying infrastructure charges doesn't guarantee cheaper houses. If landowners can capture the value created by infrastructure, some of the benefit can show up as higher land prices rather than lower house prices.

2. Will infrastructure be built before houses?

This may matter more to you than the headline dollar amount.

New Zealand already has a Housing Infrastructure Fund specifically aimed at bringing forward transport and water infrastructure in high-growth areas, including through long-term interest-free loans. Ministry for Cities and Transport

National is trying to make financing tools such as development levies much easier to use, while NZ First is proposing a stronger requirement that infrastructure be demonstrably funded before fast-tracked housing is approved. National Party

That's potentially important for the housing supply problem: land that is technically zoned for housing isn't particularly useful if nobody can finance the wastewater plant, pipes, roads and transport capacity needed to make the homes viable.

3. Does the policy actually make houses cheaper—or merely make more houses possible?

This is where I'd be cautious about campaign claims.

Getting infrastructure financed can increase the supply of buildable land, which should put downward pressure on land/housing prices over time. But infrastructure charges, construction costs, financing costs and landowner expectations can all absorb part of that benefit.

So if you're voting primarily from the perspective of two working renters trying to get onto the property ladder, I wouldn't judge an infrastructure policy solely by its funding mechanism.

I'd ask:

Will this policy increase the number of genuinely buildable homes fast enough that the extra supply outruns demand—and who bears the cost while that happens?

That's the part most likely to affect whether the deposit target you're chasing eventually becomes more achievable.

If you want, I can next compare National vs Labour vs Greens vs ACT specifically on what their 2026 housing policies mean for a couple saving a first-home deposit—including taxes, rental policy, house prices, KiwiSaver/first-home assistance, and infrastructure.
