New Zealand 2026 election: Grocery prices and household bills

The central economic question in New Zealand's 2026 general election is how parties would help households manage the cost of living, particularly supermarket shopping, electricity, housing, transport and other everyday expenses.

To compare the parties fairly, it's useful to separate three things: reducing prices directly, increasing the money households have available, and changing the market or public services to reduce costs over time. These approaches can produce different results, even when parties say they share the same goal of making life more affordable.

An important distinction is between policies already in place, formally announced election commitments, and proposals that parties are still developing. The comparison below focuses on the main policy differences and should not be read as a claim that every measure is a confirmed 2026 campaign promise.

1. Grocery prices: where the parties differ

One of the clearest findings of the 2026 campaign is that most major parties agree supermarket competition is a problem, but disagree about how directly the government should intervene. The proposals range from splitting up existing supermarket businesses to creating a government-owned competitor or making it easier for new supermarkets to open. Consumer NZ's election comparison explains the differences. consumer.org.nz

National: split Foodstuffs if the regulator supports it

National proposes separating Foodstuffs' supermarket brands into two genuinely competing nationwide grocery chains.

• What would change: New World and Four Square would form one chain, while PAK'nSAVE would become another, competing with Woolworths.
• How it could help: More independent competition could encourage lower prices, better specials and greater choice.
• The condition: National says the Commerce Commission must first assess whether the separation would benefit consumers. The party proposes legislation in its first 100 days in government to enable that process, with a recommendation due within six months.
• What to watch: The policy is not a promise of an immediate reduction in supermarket prices. Its effect would depend on how the separation was implemented and whether the new businesses competed more aggressively. national.org.nz, consumer.org.nz

National's broader economic approach also emphasises controlling government spending, returning the government accounts to surplus and introducing no new taxes. Its argument is that economic stability and a stronger economy support household prosperity. national.org.nz

Labour: tougher rules against excessive prices

Labour's approach focuses on curbing the market power of large companies and giving smaller competitors a better chance.

Its proposed measures include:

• Ban excessive pricing: Make it illegal for large companies to charge excessive prices for essential goods and services, including groceries, electricity and fuel.
• Recover overcharges: Require companies found to have overcharged consumers to pay back the excess.
• Open up supermarket wholesale supply: Require major supermarkets to make wholesale supplies available to smaller retailers on fairer terms, helping independent grocers compete.
• Strengthen consumer protections: Crack down on hidden fees and other practices that make everyday services more expensive. labour.org.nz, consumer.org.nz

Labour argues that households need action on both prices and their weekly budgets. Its wider cost-of-living package includes freezing fuel tax for three years, capping public transport fares and offering government-backed, low-interest loans for household solar installations. labour.org.nz

The key difference from National: Labour proposes directly regulating excessive prices and wholesale access, rather than making supermarket separation the centrepiece of its grocery policy.

Green Party: create a publicly owned supermarket chain

The Greens have proposed a more direct structural intervention: establishing a publicly owned supermarket chain called KiwiMart.

The party's Affordable Kai policy proposes:

• Requiring at least 120 supermarket stores and distribution-centre capacity to be sold into public ownership.
• Establishing KiwiMart with affordability as its priority.
• Banning excessive supermarket pricing, with the approach also extending to energy and fuel.
• Giving the Commerce Commission more funding, powers and enforcement tools.
• Investing in food security, including community food organisations and school lunches. greens.org.nz

The idea is that a publicly owned supermarket focused on affordability would introduce a new competitive force and put pressure on existing chains.

The proposal would require substantial public investment. The Greens' announcement cites Parliamentary Library modelling estimating approximately $1.3 billion to acquire the stores and distribution centres, plus another $1.5 billion to capitalise KiwiMart. greens.org.nz

The key difference from Labour: Both want stronger action against excessive pricing, but the Greens also propose creating a government-owned supermarket competitor.

New Zealand First: break up the supermarket duopoly

New Zealand First also wants a structural change to the supermarket industry.

Its proposal would split Foodstuffs into two competing cooperatives:

• One operating New World and Four Square.
• The other operating PAK'nSAVE.

The party argues that stronger competition would improve prices for shoppers and fairness for food producers. It also proposes stronger competition enforcement and tougher penalties for serious breaches. nzfirst.nz, consumer.org.nz

The key difference from National: Both support separating Foodstuffs' supermarket businesses, but National makes the change conditional on a Commerce Commission assessment. New Zealand First has campaigned for the breakup as a policy in its own right.

ACT: make it easier for new competitors to enter

ACT takes a different approach, arguing that the priority should be removing barriers that prevent new supermarkets from entering the market.

Its proposals include:

• Creating a single, streamlined approval process for new supermarkets.
• Making it easier and faster to obtain the necessary consents and licences.
• Accepting food labels from several overseas regulators by default.
• Opposing government-directed supermarket breakups and price-gouging rules of the kind proposed by Labour and the Greens. consumer.org.nz, act.org.nz

The underlying argument is that more businesses should be able to enter the market and compete on price, rather than the government dictating how existing supermarket groups are structured.

The key difference: ACT favours lowering barriers to entry, while National and New Zealand First propose separating existing businesses, and Labour and the Greens also favour stronger intervention against excessive prices.

Te Pāti Māori: Māori-owned supermarkets and direct food support

Te Pāti Māori's approach combines community ownership with direct assistance for households struggling to afford food.

Its proposed $3.1 billion Kai Sovereignty package includes:

• Supporting Māori collectives to establish Māori-owned supermarket chains and other retail alternatives.
• Providing $100 million in seed funding for those initiatives.
• Introducing a kai tax credit for people earning $60,000 or less, intended to cover up to eight weeks of food a year. consumer.org.nz

The party's approach is not simply about increasing competition between existing supermarket companies. It also seeks to expand community control over food production and retailing while helping eligible households afford groceries.

2. Household bills beyond the supermarket

Grocery prices are only part of the cost-of-living debate. Electricity, petrol, public transport, healthcare and housing-related costs can all affect how much money a household has left at the end of the week.

Here are the main differences in the parties' approaches.

Party	Main approach	Examples of proposed measures
National	Fiscal restraint, economic growth and targeted changes to markets	No new taxes; an affordable-power programme; support for household energy independence. national.org.nz
Labour	Direct help with bills and stronger consumer protections	Three free GP visits a year, removal of the $5 prescription charge, fuel-tax freeze, public transport fare caps and solar loans. labour.org.nz
Greens	Public investment, stronger regulation and community-based support	KiwiMart, food-security funding, stronger action against excessive pricing and expanded school lunches. greens.org.nz
ACT	Increase supply, encourage investment and reduce regulatory barriers	More electricity generation, easier household power generation and selling, and changes to electricity network regulation. act.org.nz, act.org.nz
New Zealand First	Structural reform of concentrated markets	Breaking up the supermarket duopoly and separating electricity generation and retail businesses. nzfirst.nz
Te Pāti Māori	Direct food assistance and community ownership	Māori-owned supermarket initiatives and a proposed kai tax credit for eligible households. consumer.org.nz

These are different mechanisms for addressing affordability. Some seek to reduce the price charged for a product or service; others aim to lower the cost of supplying it; and others would provide households with financial support or reduce what they need to spend on essential services.

3. Electricity prices: regulate prices or increase supply?

Electricity is another major dividing line. The parties broadly agree that households need more affordable power, but they differ over whether the main solution is to change market rules, increase competition, or encourage more electricity generation.

National: expand energy supply and help households reduce bills

National's energy programme focuses on a more secure electricity supply, investment in generation and measures to help households become more energy-independent.

Its policies include an energy plan aimed at addressing the factors driving up power bills and a Home Energy Fund intended to help households electrify their homes and reduce their reliance on purchased energy. National Party policy platform

The central approach is to address supply and infrastructure problems while encouraging investment.

Labour: make overcharging illegal and help households install solar

Labour proposes two main forms of assistance.

• Consumer protection: Make excessive electricity pricing illegal and require companies found to have overcharged customers to repay the excess.
• SolarSaver: Offer government-backed, low-interest loans for solar panels and batteries, with additional support of up to $3,000 for eligible low- and middle-income households.

Labour estimates that participating households could save around $1,000 a year on power bills. That is a party estimate, not a guaranteed saving for every household. Renters would also be able to benefit through plug-in solar. Labour's cost-of-living plan

ACT: increase electricity generation and competition

ACT argues that electricity prices are driven partly by insufficient supply and barriers to investment.

Its proposed measures include:

• Making it easier to invest in new electricity generation and infrastructure.
• Allowing households to sell surplus electricity to whichever provider offers the best deal.
• Opening parts of the electricity transmission market to private investment.
• Allowing more competition in electricity network connections and encouraging alternatives to expensive network upgrades.

ACT's argument is that increasing supply and reducing barriers to competition will put downward pressure on prices. ACT's electricity policy

New Zealand First: break up the electricity gentailers

New Zealand First proposes separating electricity generation and retail operations, targeting companies that participate in both parts of the industry.

The party argues that separating these functions would reduce market concentration and improve competition over electricity prices. New Zealand First policy platform

The difference is similar to the supermarket debate: New Zealand First wants structural separation of existing companies, while ACT emphasises increasing supply and opening the market to more competition and investment.

4. What do these differences mean for household budgets?

The practical effects depend on which costs matter most to an individual household and whether the proposed policies achieve their intended results.

Household concern	Policies most directly relevant
High supermarket prices	National's proposed Foodstuffs separation; Labour's excessive-pricing rules and wholesale reforms; the Greens' KiwiMart proposal; New Zealand First's supermarket breakup; ACT's easier entry for new competitors.
High electricity bills	Labour's proposed price controls and solar loans; ACT's emphasis on supply and competition; National's energy programme; New Zealand First's proposed separation of generation and retail businesses.
Petrol and transport costs	Labour's fuel-tax freeze and public transport fare caps.
Healthcare expenses	Labour's proposed free GP visits and removal of prescription charges.
Difficulty affording food	Te Pāti Māori's proposed kai tax credit and Māori-owned retail initiatives; the Greens' food-security funding and expanded school lunches.
General economic security	National's emphasis on fiscal restraint and no new taxes; Labour's combination of direct cost-of-living measures and employment policies; other parties' differing proposals for regulation, taxation and public investment.

5. What should voters look for when comparing the promises?

There are three particularly important questions to ask of any party's cost-of-living programme.

1. Will it reduce prices, or simply help people pay them?

These are different outcomes. A subsidy, tax reduction or tax credit can leave a household with more money to spend without reducing the underlying price of groceries or electricity. Competition reforms, meanwhile, aim to change the prices businesses charge, but the results depend on how markets respond.

2. How quickly could households benefit?

Some proposals, such as removing prescription charges or freezing a tax, could affect expenses relatively directly once implemented. Creating a new supermarket chain, restructuring an existing company or building additional electricity generation would require implementation and could take longer to affect household budgets.

3. What are the costs and trade-offs?

A publicly owned supermarket would require substantial government investment. Breaking up an existing supermarket group could increase its operating costs if infrastructure had to be duplicated. Conversely, making it easier for new businesses to enter a market does not guarantee that new competitors will emerge or that prices will fall.

Consumer NZ highlights these uncertainties in its 2026 supermarket policy comparison. Party estimates of savings should be distinguished from independently established outcomes.

Bottom line

The main competing approaches in New Zealand's 2026 election can be summarised as follows:

• National: Increase competition through a potential supermarket separation, encourage investment and maintain fiscal restraint.
• Labour: Regulate excessive prices, improve wholesale access for smaller businesses and directly reduce several household expenses.
• Greens: Create a publicly owned supermarket, strengthen price regulation and invest in food security.
• ACT: Remove barriers to competition, encourage new businesses and increase electricity supply.
• New Zealand First: Break up concentrated supermarket and electricity businesses and strengthen enforcement.
• Te Pāti Māori: Expand Māori ownership of food retailing and provide targeted assistance to households struggling to afford food.

The most significant divide is not whether grocery prices and household bills matter. It is whether government should primarily reshape markets, regulate the prices companies charge, provide direct financial assistance, or encourage investment and competition to bring costs down.

The important question for voters is which combination of measures they believe would address their own household expenses, while also considering the proposals' funding, implementation time and likely effects on prices.
