What the parties' tax plans would mean for a retired couple
RNZ has compared how party policies could affect household budgets, under the title 'Which political party would make you better off?'.
The piece, by Money Correspondent Susan Edmunds and published on 4 October 2026, models two households. It is listed in the broadcaster's RNZ Election Policy Guide 2026 with a date of 5 October. RNZ
Scenario 1 is a retired couple with a $2 million freehold home, about $15,000 a year of other income on top of NZ Super in one person's name, and no children in their care. Scenario 2 is a young first-home-owning family with two primary-school-age children and incomes of $100,000 and $50,000.
For the retired couple, RNZ reported the basic financial position would be broadly unchanged under a future National government.
Finance Minister Nicola Willis said National will campaign on some tax policies and wants tax brackets to change, but said that would not be appropriate until the books were back in surplus. A surplus means the Government collects more than it spends. The party's 2026 policy position is for no new taxes, keeping taxes unchanged so people retain more of their earnings.
ACT has a goal of a two-rate income-tax structure with a top rate of 28 percent. New Zealand First pledges to restrict superannuation to citizens from 2029. RNZ did not attribute a dollar figure to either position for the retired couple in the material provided.
Labour, Greens and Te Pāti Māori
Labour proposed a 28 percent capital gains tax applying only to residential investment and commercial property, with the family home exempt. The tax applies to the profit when an investment is sold. That design means the Scenario 1 couple, in a mortgage-free owner-occupied home, fall outside its scope.
Labour's Fiscal Plan 2026 also proposes freezing fuel tax for three years. It proposes capping weekly public transport fares at $20 in Auckland, Wellington and Christchurch, and $10 everywhere else.
The Green Party proposes a $20 million wealth threshold for a couple and a $10,000 tax-free income band, the amount earned before tax starts. RNZ's modelling estimated Green Party policies would leave the retired couple about $2,769 a year better off. RNZ
The Greens also propose a 33 percent capital acquisitions tax on inheritances above $1 million, with exemptions for family homes and farms. Separately, the party proposes a 2.5 percent tax on net assets above $10 million, with an exemption for family homes.
Te Pāti Māori proposes a $4 million wealth tax exemption for a couple. It proposes no tax on income up to $30,000 and 15 percent from $30,001 to $60,000, which RNZ estimated would leave the retired couple about $7,809 a year better off.
The party also proposes a 5 percent stamp duty usually paid by the buyer, a purchase tax added at sale time, equating to $100,000 on a hypothetical $2 million sale price. The duty would not apply unless the property transacts. It would fall on the purchaser rather than the Scenario 1 vendors if they sold.
The Opportunity Party offer
The Opportunity Party proposes a 1.75 percent annual urban land value tax, which RNZ calculated as about $19,250 a year for the $2 million property, deferrable until the property is sold. Deferral shifts timing of liability rather than removing it.
The party proposes a $19,400-a-year Citizen's Income for each eligible adult, topped up so superannuitants receive the same amount they currently get from the pension. For the retired couple, the interaction is therefore between a new land-based liability and a flat-rate payment that holds superannuitants at existing pension levels.
Other publishers are running parallel guides. The New Zealand Herald publishes an Election 2026 Policy Grid covering education, health, housing and tax to compare major party policies. New Zealand Herald The Conversation publishes a 2026 New Zealand election policy tracker guide to what the parties are promising.
The broader context here is familiar to anyone who has watched Budgets and election campaigns from the Gallery. Illustrative households clarify trade-offs, but they do not settle them. A couple with most of their wealth in an exempt family home faces a different question from an investor or a buyer, and a land tax that can be deferred still changes incentives at the point of sale. For policy staff, the numbers to watch are thresholds, rates and timing rules rather than the headline annual gain or cost.
In my view, the value of this exercise is in the side-by-side treatment of income tax scales, wealth thresholds and transaction taxes. National and ACT are offering restraint and flatter income tax structures, with action conditional on surplus. Labour, the Greens, Te Pāti Māori and The Opportunity Party each use a different base: realised gains on investment property, net wealth above a high threshold, stamp duty at purchase, or annual land value. Readers in the Beehive will already be asking how each base would be defined in legislation, how it would be valued and audited, and what behavioural response Inland Revenue would be asked to cost.
