Green Party cost breakdown

Week 9 update:

• The Greens’ total is unchanged at $272.31 billion, or $131,425 per household. Their own fiscal plan still raises a net $28.75 billion over the same four years, leaving $243.56 billion, or 89.4 percent of their spending, unfunded: $117,550 per household.

-----------------

The Green Party’s fully costed policies amount to $272.3 billion in new spending over the next four years, equivalent to $131,425 per household. Their own fiscal plan raises a net $28.75 billion over the same period, leaving $243.56 billion of this spending unfunded ($117,550 per household).

Social spending

Social spending is costed at $179.4 billion over four years, or $86,578 per household, by far the largest single category. Extending ACC to cover all injuries, disability and illness regardless of origin accounts for $96 billion of that alone, based on a 1988 Royal Commission estimate that the extension would cost roughly four times the existing scheme. Lifting benefits to "liveable rates" adds a further $27.6 billion.

On education, a universal student allowance to cover basic needs is costed at $14.4 billion, and free tertiary education up to a first degree at $8 billion, based on 257,000 students at an average $8,000 tuition fee. The party's proposed student loan write-off carries a $16.2 billion balance sheet impact, with no confirmed profit and loss impact separately available. Free early childhood education for all is costed at $5.4 billion, free school lunches for all kids in all schools at $2.2 billion, and expanding free apprenticeship programmes at $200 million.

The Greens would pay students on nursing, teaching and social work placements $380 a week. The Greens give no costing, but we have calculated $289 million over four years. Their $1,500 relocation payments for students who have to move for a placement add a further $21 million, on our assumption that a quarter of placements involve relocation. The Greens would also abolish the training wage, with no costing. We have costed the package that goes with it at $402 million: a $2,000 equipment grant for each apprentice ($178 million), a $2,000 employer completion bonus ($103 million), and a $30 million a year Māori and Pasifika training uplift ($120 million), the last taken at the Greens’ figure.

Paid parental leave extended to 65 weeks, 39 more weeks, for an estimated 56,000 parents, is costed at $6.6 billion. Increasing Pharmac funding by 10 percent of the 2026/27 medicines budget adds $720 million, and writing off Ministry of Social Development debt a further $1.37 billion.

Economic development

The Greens’ economic development spending is costed at $54.7 billion over four years, or $26,393 per household. Transport is now the largest commitment at $24.3 billion ($11,719 per household), following the release of the Greens’ 2026 transport policy. Passenger rail and mass rapid transit is costed at $21.1 billion: $13.65 billion for light rail, $4.02 billion for intercity passenger rail (including Te Huia), $900 million for Wellington metro rail renewals and $2.5 billion for West Auckland level crossings. Taxpayer-funded and capped public transport fares add $1.28 billion, and covering councils’ public transport funding shortfalls adds $824 million, which includes bus priority lanes and replaces our earlier $1.2 billion bus lanes estimate. Inter-regional buses are costed at $407 million, walking and cycling at $290 million, electric buses at $75 million, and EV subsidies, based on reintroducing the Clean Car Discount, at $337 million.

A further $9.4 billion is costed for tens of thousands of new public homes, based on forecast 2026/27 house-building spend and the maximum build rate achieved in 2023/24, alongside $21 million for a Certified Rental Warrant of Fitness.

Regional support adds $2.44 billion for Te Waonui a Tāne, the marae trust that includes the Te Rākau restoration fund and the intergenerational fund, taken from the Greens’ fiscal plan.

Energy policies add a further $3.05 billion, made up of Kiwipower ($980.6 million), expanding Warmer Homes ($969.8 million), solar on all public housing stock ($460 million), zero-interest solar loans ($428.7 million), community-owned energy ($200 million), and increased EECA funding ($12.4 million).

Using MBIE figures provided to Cabinet in 2023, we have estimated the Greens' plans to purchase 120 supermarkets to form a state-run supermarket chain at $4.7 billion, or $2,259 per household. Creating a tribunal for dealing with disputes arising from auctioning off commercial leases on unoccupied lots has been costed at $7.2 million. The Greens’ ‘A Job for Every Young Person’ jobs guarantee is costed at $4.86 billion over four years, or $2,346 per household.

The Greens’ economic development plan, which they estimate at $5.94 billion over four years ($2,869 per household), is included at their own costing. The Greens have also promised a $225 million a year boost to tertiary, science and research funding as part of that plan. We have counted it within the $5.94 billion, so it is a nil in the table. If it is additional, it would add $900 million.

Environment and arts

Environment and conservation commitments total $1.6 billion over four years, or $773 per household. This includes $1.25 billion to expand Jobs for Nature, $200 million to introduce a price on agricultural emissions, $90 million to restore the Ministry for the Environment, and $13.5 million to increase funding for the EPA and community environment groups, based on a 10 percent uplift of the EPA’s 2026/27 functions budget. Protecting 30 percent of the Hauraki Gulf by 2030 adds $52.5 million, which we have costed by scaling the Department of Conservation’s $10.5 million cost of establishing the Gulf’s current protected areas (about 6 percent).

$200 million has also been promised for the promotion of te reo Māori.

Government services and administration

The Greens’ fiscal plan adds $21.80 billion of operating allowances above Treasury’s forecasts over four years, or $10,521 per household. The plan describes this as primarily a health uplift of $3 billion a year, rising to $12 billion in the fourth year. Net of the plan’s lower non-health allowances, the increase above Treasury’s track is $21.80 billion. The plan also restores public sector baselines ($3.17 billion) and funds the IRD ($413 million) for tax enforcement. We have assumed the baselines line replaces their manifesto's public service pledges. We have costed reinstating the pay equity regime at Treasury’s $10.97 billion, or $5,295 per household. The plan includes $4.48 billion for pay equity, about 41 percent of Treasury’s projection.

The Greens’ AI policy sets out five goals but gives no costing. We have costed at $29.2 million by assuming it mirrors Labour's similar proposals.

The Greens have proposed a lobbyist register and commission, and restrictions on political donations. We have costed this at $48 million over four years, matching the lobbying and donations part of Opportunity's clean up politics package.
