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. How would party tax and family-support plans change the finances of a two-income family?
How 2026 election policies could affect your household finances
For a family with a mortgage, school-age children and two working parents, the important question is not simply which party promises tax cuts. It is:
How much extra money would actually remain in your bank account each fortnight after tax, childcare and family costs—and would that be offset by higher costs elsewhere?
I would compare the parties across five areas:
- Income tax changes for both earners.
- Family payments, including Working for Families.
- Childcare and education support.
- Rates, housing and household-related costs.
- Public services and other costs that might affect your disposable income.
One important distinction: a tax cut is not necessarily a family benefit. A household with two moderate incomes can have a different outcome from one high-income household, even if their combined income is identical.
1. What the main parties are proposing
The following reflects published 2026 election policies and announcements available around October 2026. These are proposals, not enacted changes.
| Party | Main household tax approach |
|---|---|
| National | No new taxes pledge; has indicated interest in addressing bracket creep, but no formal personal tax-cut package was published in the tax comparison. |
| Labour | 28% capital gains tax on investment and commercial property gains, excluding the family home; free healthcare measures and higher employer KiwiSaver contributions. |
| Green Party | First $10,000 of each person's income tax-free, with higher rates for higher earners; wealth and inheritance taxes. |
| ACT | A proposed simpler, flatter income-tax structure with a 28% top rate; tax-free KiwiSaver investment gains. |
| New Zealand First | Proposes making the temporary Working for Families in-work tax credit increase permanent, as well as small-business tax changes. |
| Opportunity | A $19,400 annual Citizen's Income for eligible adults, alongside a land-value tax and redesigned income-tax and benefit systems. |
| Te Pāti Māori | First $30,000 of income tax-free, targeted food-related tax credit and wealth taxes. |

2. What this could mean for a family with two incomes
There is a particularly useful published comparison from RNZ and the Otago Daily Times.
They modelled a family with:
- One parent earning $100,000.
- The other earning $50,000.
- Two primary-school-aged children.
- A $900,000 home.
- An $800,000 mortgage.
- Land valued at $600,000.
This is an illustrative scenario, not a prediction for every family.

Here is what sits behind those differences.
National
- Expanding the First Home Loan scheme to households earning up to $300,000 combined could help families still trying to buy.
- Extending paid parental leave to 30 weeks could help if you have another child.
- Compulsory KiwiSaver contributions would eventually rise to 6% from both employers and employees.
For an existing homeowner, the first-home scheme is unlikely to help directly. Higher employee KiwiSaver contributions could also reduce take-home pay, even though retirement savings increase.
Labour
- The family home would be excluded from its proposed capital gains tax.
- Three free GP visits per year and free prescriptions for fully funded medicines could reduce out-of-pocket healthcare costs.
- Higher compulsory employer KiwiSaver contributions would eventually reach 6%.
The employer contribution proposal is worth examining carefully: it could improve retirement savings without requiring the same increase in employee contributions.
Green Party
- The first $10,000 of each adult's income would be tax-free.
- Its model estimated the example family would gain around $1,086 annually.
- Its proposed wealth tax would not affect the modelled family, which is well below the relevant threshold.
The higher 45% income-tax rate applies to income above $160,000, so it would not directly affect the example household.
ACT
- A lower, flatter income-tax structure could reduce income tax, particularly for higher earners.
- Removing tax on KiwiSaver investment earnings could improve long-term retirement balances.
The benefit depends on the final tax brackets and each person's individual income.
New Zealand First
- Proposes making the temporary $50 weekly increase to the Working for Families in-work tax credit permanent and adding another $70 weekly.
- Proposes a Kiwi Kids Grant of up to $5,000 per child annually for up to three children, subject to its eligibility rules.
The Working for Families proposal is particularly relevant to households with children, although the actual benefit depends on eligibility and the way the credit interacts with existing payments.
Opportunity
- Offers eligible adults $19,400 annually through its Citizen's Income.
- Proposes an annual 1.75% urban land-value tax.
- For the example household, the estimated land tax was $10,500 annually, compared with $38,800 in combined Citizen's Income.
The reported net improvement was approximately $13,836 annually. However, existing Working for Families and other payments could change under its proposed redesigned system. This needs to be assessed as a whole, rather than simply adding the Citizen's Income to existing support.
Te Pāti Māori
- No income tax on the first $30,000.
- A proposed Income Tax Kai Credit for people earning $60,000 or less.
- The modelled household was estimated to gain approximately $9,236 annually.
The lower-earning parent in the example could qualify for the Kai Credit. The family home and its first-home-buyer status also matter when considering its proposed property-related taxes.

3. What about your mortgage, rates and everyday bills?
This is where it is important to look beyond income tax.
| Household expense | What party policies could change |
|---|---|
| Mortgage | No major party proposal directly reduces existing mortgage principal or guarantees lower mortgage rates. Fiscal policy can indirectly affect interest rates. |
| Council rates | National has proposed keeping rates affordable through changes to council responsibilities and spending. |
| Electricity | National has an affordable-power programme; other parties have different energy and competition policies. |
| Groceries | Labour proposes stronger grocery-price competition measures; NZ First also proposes addressing supermarket dominance. |
| Healthcare | Labour's free GP visits and prescriptions could reduce costs. |
| Children's expenses | Working for Families, food credits, childcare and education support can make a significant difference. |
One important point: Opportunity's proposed land-value tax deserves particular attention from homeowners. It is based on land value rather than the value of the house itself.
Also, Labour's proposed capital gains tax would exclude your family home, so simply owning a home with a mortgage would not make you liable for that proposed tax.

4. The questions I would investigate before voting
Given that you are already meeting substantial fixed expenses, I would pay particular attention to:
- Fortnightly cash flow: How much additional take-home income would both parents receive?
- Family support: Would you qualify for additional Working for Families payments or other child-related assistance?
- Mortgage exposure: Could the proposed fiscal settings affect interest rates over the next three years?
- KiwiSaver: Would increased contributions come out of your wages, or be additional employer contributions?
- Cost shifting: Could lower taxes be accompanied by increased costs for healthcare, education or other services?
Another consideration is that New Zealand uses MMP. The policies a party campaigns on may be modified during coalition negotiations. There is no guarantee that every proposal will become law.
5. Let's calculate what the parties could mean for your actual household
The published $100,000/$50,000 example is useful, but your own income split and mortgage situation could produce quite different results.
I can build a household comparison showing estimated annual and fortnightly differences under each party's proposals.
I just need four details:
Your household details
My aim would be to show you not just which policies offer tax relief, but which proposed changes could realistically leave your family with more money available for groceries, bills, mortgage payments and savings.
You deserve to be able to compare the actual household consequences rather than having to rely on campaign slogans.
