We own a home with a mortgage, have school-age children and rely on two wages. After mortgage payments, rates, power and groceries, there is little buffer. I am considering my vote in the 2026 New Zealand general election. What are the parties proposing about household costs, and which proposals would actually apply to a working family like ours?
For a New Zealand family with a mortgage, school-age children and two incomes, the key question for the 2026 general election is not simply which party promises to lower the cost of living. It is which policies would leave more money in your household budget, when they would take effect, and whether your family would actually qualify.
I'd compare the parties across five areas:
- Mortgage and housing costs: interest deductibility for landlords, housing supply, homeownership policies and any measures affecting mortgage rates.
- Tax and take-home pay: income-tax changes, tax credits and whether benefits depend on your income or number of children.
- Children and education: Working for Families, childcare subsidies, school costs and school-related assistance.
- Everyday bills: electricity, fuel, groceries, rates and public transport.
- Public services and trade-offs: whether proposed savings in taxes or bills come alongside changes to health, education, transport or other services your family uses.
One important distinction: a policy can sound generous nationally without putting much money into your particular household. For example, an income-tax cut depends on your taxable incomes; a targeted family payment depends on eligibility rules; and a proposal to increase housing supply may take years to affect prices.
1. What the main parties are proposing
The comparison below uses policies published for the 2026 election as of 11 October 2026. It separates direct household assistance from longer-term changes that might eventually lower costs. These are party commitments, not guaranteed outcomes; legislation, funding and implementation still matter.
National
National Party
National's approach centres on lower taxes, targeted help, competition and keeping government spending under control. Its 2026 policies include more grocery competition, a Home Energy Fund to help households electrify their homes, and a commitment to keep council rates affordable. 2026 Election PolicyCost of living relief
- Groceries: National proposes separating New World and PAK'nSAVE so they compete more directly.
- Power: its Home Energy Fund is intended to help households reduce energy costs by electrifying their homes.
- Rates: it proposes refocusing councils on core services to help contain rates.
- Family support: National's existing cost-of-living package includes increases to Working for Families for eligible families, as well as temporary fuel-related assistance. 2026 Election PolicyCost of living relief
For your household: grocery competition and lower energy use could help regardless of income. Family tax credits are more directly relevant if your combined income and number of children qualify. The rates commitment is not a guaranteed reduction in your particular council bill.
Labour Party
Labour is emphasising competition, lower transport and healthcare costs, and stronger consumer protections. Labour's 2026 Election PoliciesLabour's Fiscal Plan 2026
- Transport: a weekly cap of $20 on bus and train fares, scheduled for 1 July 2027.
- Healthcare: three free GP visits a year for everyone under its proposed Medicard, and free prescriptions from 1 July 2027.
- Groceries: breaking open supermarket wholesale supply so smaller retailers can compete more effectively.
- Everyday charges: a proposed Fair Go Law targeting hidden fees, cancellation traps and junk insurance, plus action against price gouging by large companies. Labour's 2026 Election PoliciesLabour's 2026 Election Policies
For your household: the transport cap matters most if you use buses or trains. Free prescriptions and GP visits could release money otherwise spent on healthcare. Grocery and consumer reforms could help, but the size of any savings is not guaranteed. These policies do not directly reduce your mortgage repayment.
Green Party
The Greens propose changing tax settings and increasing public intervention in energy and housing. Manifesto 2026Greens commit to tax the super-rich and large corporates fairly, cut income tax for 96%Power for all of us
- Income tax: a tax-free threshold on the first $10,000 of income, with a higher tax rate on income above $160,000.
- Power: a publicly owned energy company called Kiwipower, zero-interest clean-energy loans covering up to 90% of eligible homeowners' costs, and expanded insulation and energy-efficiency support.
- Housing: reversing landlord tax cuts and changing tax settings affecting investment property.
- Funding: a proposed 2.5% annual tax on net assets above $10 million, excluding family homes, alongside higher taxes on some large corporations. Greens commit to tax the super-rich and large corporates fairly, cut income tax for 96%Power for all of us
For your household: the income-tax proposal could benefit both wage earners, while energy loans could help if you own your home and want to install eligible improvements. The power company's effect on bills would depend on implementation and market outcomes. The proposed wealth tax specifically exempts family homes, but other tax changes and their effects on the wider economy would need to be considered separately.
ACT New Zealand
ACT's fiscal plan emphasises reducing government spending, controlling debt and creating scope for lower taxes. Its energy policy proposes opening electricity networks to more competition and requiring lines companies to demonstrate value for costs charged to consumers. ACT New ZealandACT New Zealand
- Taxes: ACT's longer-term objective is lower, flatter taxes, supported by spending reductions.
- Power: more competition in electricity networks, and more freedom for households to generate and sell electricity.
- Savings: removing tax on qualifying KiwiSaver investment earnings, which is mainly a long-term savings benefit rather than an immediate pay rise. ACT New ZealandACT New ZealandACT New Zealand
For your household: any tax reduction would depend on the final tax rules and your incomes. Energy-market reforms could benefit consumers over time, but they do not promise an immediate, fixed reduction in your power bill. Spending reductions may also affect public services your family uses.
New Zealand First
Its published campaign policies include breaking up the supermarket duopoly and electricity generator-retailers, as well as changing the energy sector's structure. NZ First Campaign Policy Announcement: NZ First Will Break Up the Supermarket Duopoly, Bring Food Prices Down for KiwisOur Policy
- Groceries: split Foodstuffs into two nationwide cooperatives to increase competition with Woolworths.
- Power: separate electricity generation from retail to change how the market operates.
- Families: a proposed Kiwi Kids Grant would support eligible New Zealand citizens raising children during their first three years of life. NZ First Campaign Policy Announcement: NZ First Will Break Up the Supermarket Duopoly, Bring Food Prices Down for KiwisOur PolicyNZFirst Announces Policy to Encourage Kiwis To Have More Kids
For your household: the supermarket and electricity proposals are relevant to regular bills, but savings would depend on how the market responds. The Kiwi Kids Grant is designed for families with very young children, so it would not directly assist a family whose children are already school-age.

2. Which proposals could actually help your family?
For a two-income homeowner with school-age children, the biggest distinction is between help you might qualify for directly and policies that depend on the market changing.
| Household expense | What could make a difference | What to check |
|---|---|---|
| Mortgage | Tax changes that increase take-home pay; broader economic effects on interest rates | No major proposal above guarantees a lower repayment on your existing home loan. |
| Rates | National's council-cost proposals | Rates are set by your local council; the policy does not guarantee your bill will fall. |
| Power | National's Home Energy Fund; Greens' clean-energy loans and Kiwipower; ACT's competition reforms | Eligibility, upfront costs, loan repayment terms and how quickly savings arise. |
| Groceries | National's and Labour's supermarket reforms; NZ First's proposed supermarket split | These are competition measures, not guaranteed discounts at the checkout. |
| Children's costs | Working for Families and any eligible family assistance | Your combined income, number of dependent children and their ages. |
| Transport | Labour's public-transport fare cap | Whether your family uses eligible bus and train services. |
| Healthcare | Labour's proposed free GP visits and prescriptions | Whether you currently pay these costs and when the policy starts. |

Check this before assuming you won't qualify for family support
Having two wages does not automatically rule your family out of Working for Families. Inland Revenue generally assesses the combined income of you and your partner, along with your family circumstances. The amount can reduce as family income rises. Working for Families overviewIn-work tax credit
You can check your circumstances using the official Working for Families information and eligibility tools.
Also distinguish existing assistance from new election promises. For example, the in-work tax credit has a temporary fuel-related increase under current rules from 1 April 2026. It is not simply a new benefit that every working household will receive indefinitely: eligibility, the fuel-price condition and the end date matter. In-work tax creditCost of living relief
3. What about your mortgage?
This deserves separate attention because it is likely to be one of your largest expenses.
- Your mortgage interest rate: the Reserve Bank's monetary policy and broader economic conditions affect mortgage rates. A party cannot guarantee that its policies will make your bank reduce your rate.
- Tax deductions for landlords: proposals to restore or reverse landlord interest deductibility concern investment properties, not a direct tax deduction for the interest you pay on your own family home.
- Building more homes: changes to housing supply may affect affordability over time, but they are not immediate relief for an existing mortgage.
- Take-home pay: a tax cut could give either or both wage earners more money to work with, depending on the policy's tax brackets and your incomes.
In practical terms, when comparing mortgage-related claims, look for an actual change to your household's disposable income rather than a general promise to make housing more affordable.
4. A practical way to compare the election policies
Rather than trying to decide from headline promises, calculate the effect under three time horizons:
Money available now
Existing entitlements, any immediately effective tax changes, and assistance your family qualifies for today.
Changes in the first year
Proposed changes to fares, healthcare fees, taxes or family payments, accounting for their start dates and eligibility rules.
Longer-term savings
Potential changes to electricity prices, grocery competition, housing supply and council costs. Treat these as uncertain until the savings are demonstrated.
5. If you'd like a more specific comparison
I can estimate how the relevant policies might affect your household without assuming which party you support. The two details that would make the biggest difference are your combined income and how many children you have.
Optional details — estimates will depend on the final policy rules.
You do not need to share exact salaries, your address, or your bank or mortgage details. Approximate figures are enough to make the comparison more useful.
