Green Party Unveils Scaled-Back Tax Overhaul Targeting Wealth and Multinationals
The Green Party has launched its flagship tax policy ahead of the 2026 New Zealand general election, proposing a package projected to raise $32 billion over four years. The plan, branded "A tax system for all of us," focuses on a new levy on high-net-worth individuals, adjustments to corporate taxation, measures aimed at big tech companies, and changes to inheritance rules. Party co-leader Chlöe Swarbrick presented the proposals as a way to address inequality and fund income tax relief for the majority of Kiwis.
Officials describe the package as a more focused version of earlier ideas. It narrows the wealth tax threshold significantly compared with previous iterations while adding elements such as a capital acquisitions tax on large gifts and inheritances. The policy also includes reversing certain landlord tax settings introduced under the current coalition government and enforcing a withholding tax on offshore profits from major digital platforms.
Key Elements of the Proposed Tax Changes
Central to the plan is a 2.5 percent annual tax on net assets exceeding $10 million for individuals, or $20 million for couples. Family homes remain exempt from this calculation. Assets covered include property beyond the family home, shares, bonds, and business interests. The Green Party estimates this component alone would contribute the largest share of new revenue.
A capital acquisitions tax would apply to gifts and inheritances valued over $1 million, again with exemptions for family homes and farms. Corporate tax settings would see the rate rise from 28 percent to 33 percent for companies with annual turnover above $30 million. This targets larger entities such as major banks, supermarkets, and energy firms while leaving smaller businesses unaffected.
Additional measures include a 0.06 percent annual levy on the total liabilities of New Zealand's four largest banks and a requirement that big tech firms pay a 5 percent withholding tax on profits transferred offshore. The party also proposes reversing recent changes to the bright-line test for property investment and introducing a tax-free threshold for the first $10,000 of income, offset by a higher marginal rate on earnings above $160,000.
According to party calculations, these adjustments would result in lower income tax bills for 96 percent of New Zealanders. Revenue would support expanded public services and targeted spending priorities.
Revenue Projections and Funding Goals
The overall target stands at $32 billion across four years, substantially less than the $88 billion figure floated in the party's 2025 alternative budget. The super-rich tax is expected to generate more than half of the total. Other streams come from the corporate rate adjustment, bank levy, big tech withholding, and reversal of landlord deductions.
Green Party documents outline how the funds would help deliver income tax cuts while addressing what the party terms a "cost of greed crisis." Proponents argue the measures level the playing field for small and medium enterprises competing against multinational giants.
Prime Minister Luxon Labels Plan Economic Lunacy
Prime Minister Christopher Luxon responded swiftly, describing the proposals as economic lunacy that would act as a wrecking ball to growth. He argued the measures would discourage investment, drive talent and capital offshore, and ultimately hinder job creation and wage growth. Luxon emphasised National's focus on expanding the economy rather than redistributing existing wealth.
The Prime Minister noted that successful wealth creators and entrepreneurs would have little incentive to remain in New Zealand under such a regime. He linked the plan to broader coalition concerns about fiscal responsibility amid ongoing economic pressures, including fuel market volatility.
ACT Leader Seymour Attacks Tall Poppy Syndrome
ACT Party leader David Seymour went further, characterising the policy as an appeal to the dark underbelly of New Zealand culture through tall poppy syndrome. He portrayed it as a vision that treats success as inherently problematic and seeks to penalise those who generate wealth. Seymour suggested the approach would make high achievers fair game for punitive taxation.
These coalition responses highlight a clear divide ahead of the election campaign. National and ACT position their approach around growth and incentives, while the Greens frame their package around fairness and corporate accountability.

Labour Leader Hipkins Offers Mixed Assessment
Labour leader Chris Hipkins has previously described earlier Green tax ideas as a huge spend-up that appeared unrealistic, while acknowledging agreement on some underlying principles. The latest iteration has not yet drawn detailed commentary from Labour, though the party continues to navigate its own positioning on revenue measures.
Political observers note that any future centre-left government would likely need to reconcile differing tax philosophies between Labour and the Greens if coalition talks arise after the election.
Background on New Zealand's Tax Landscape
New Zealand currently lacks a comprehensive capital gains tax or broad wealth tax. The tax system relies heavily on income and consumption taxes, with recent governments adjusting settings around property investment through the bright-line test and interest deductibility rules. The coalition has prioritised tax relief measures, including changes benefiting landlords, which the Greens now seek to unwind.
The country's corporate tax rate of 28 percent sits below the OECD average in some comparisons, prompting ongoing debate about competitiveness versus revenue needs. Multinational digital companies have faced scrutiny globally for profit shifting, with New Zealand exploring digital services taxes in past discussions.
Economic Context and Inequality Concerns
Proponents of the Green plan point to rising inequality and the concentration of wealth among a small segment of the population. They argue that current settings allow large corporations and high-net-worth individuals to contribute proportionally less than wage earners. The party highlights examples of multinational platforms generating substantial revenue in New Zealand while routing profits offshore.
Critics counter that higher taxes on capital and business could reduce incentives for investment at a time when the economy faces headwinds. They warn of potential capital flight and reduced entrepreneurship, particularly in sectors reliant on foreign or high-wealth funding.
Implications for Businesses and Households
Small and medium enterprises could benefit from the proposed corporate rate differentiation and big tech measures, according to Green Party analysis. Larger firms facing the 33 percent rate would see increased costs, potentially passed on through pricing or investment decisions.
For households, the income tax adjustments promise relief for most earners, though those above the higher threshold would face increased marginal rates. Property owners with significant non-home assets would encounter new annual liabilities under the super-rich tax.
International Comparisons and Precedents
The proposals draw loose parallels with wealth taxes in other jurisdictions, though New Zealand's version includes higher thresholds and specific exemptions. Australia's approach to bank levies and corporate taxation features in discussions, as do European models for digital services taxation. Implementation would require careful design to avoid double taxation or administrative complexity.
Outlook for the 2026 Election Campaign
The tax package represents the Greens' opening major policy salvo for the campaign. It sets up a clear contrast with the governing coalition's emphasis on growth and restraint. Public reaction remains fluid, with polls likely to test appetite for redistribution versus incentives in the coming months.
Further refinements or corrections to revenue estimates have already surfaced in early reporting, underscoring the technical challenges of modelling such reforms. The party maintains the core figures remain robust despite minor adjustments.
As the election approaches, the debate will centre on whether New Zealand's tax system requires fundamental rebalancing or targeted tweaks to support both fairness and prosperity.
