NZ First to Campaign on Breaking Up Supermarket Duopoly

New Zealand First has confirmed it will campaign on breaking up the country’s supermarket duopoly ahead of the 2026 general election, targeting the dominant market positions of Foodstuffs’ Pak’n Save and Woolworths’ New World chains.

The party’s policy announcement, made public in mid-April 2026, positions retail competition as a central economic issue, arguing that the lack of meaningful competition between the two major grocery operators has contributed to sustained food price inflation. New Zealand First leader Winston Peters stated that the duopoly structure limits consumer choice and enables price-setting behaviour that disadvantages households.

Policy Details and Targeted Chains

New Zealand First’s proposal specifically calls for the structural separation of Pak’n Save and New World, the two largest supermarket brands operating under the Foodstuffs and Woolworths New Zealand entities respectively. The party has not proposed breaking up the companies themselves but seeks to prevent any single entity from owning both formats, effectively requiring divestment of one brand from each parent group.

Market Context and Price Pressures

Grocery prices in New Zealand have risen consistently over the past three years, with food inflation outpacing general inflation since 2023. According to Stats NZ, the food price index increased by 6.8% in the year to March 2026, driven by higher costs for staples such as bread, milk, and fresh produce. While global supply chain pressures and domestic production costs have played a role, critics argue that market concentration has amplified pricing power.

Commerce Commission investigations have previously examined the supermarket sector, including a 2022 market study that found limited effective competition in many regions. The report noted that the presence of only two major national chains reduced incentives for price competition, particularly in smaller cities and towns where independent retailers have struggled to compete.

Industry Response and Regulatory Precedent

Foodstuffs and Woolworths New Zealand have not issued formal responses to the policy announcement as of April 2026. Both companies have previously defended their market positions, citing the high costs of operating in a geographically dispersed market and the need for scale to maintain supply chain resilience.

The Commerce Commission, New Zealand’s competition regulator, has the authority to investigate market power and recommend structural remedies under the Commerce Act 1986. However, any forced divestment would require a formal investigation, evidence of substantial market power, and a determination that less intrusive remedies would be insufficient — a threshold that has not yet been met in formal proceedings.

Internationally, structural remedies in retail have been rare but not unprecedented. In 2021, the Australian Competition and Consumer Commission blocked a proposed merger between Coles and Wollworths’ Australian operations on competition grounds, though no divestment of existing assets was ordered. In the European Union, regulators have occasionally required divestments in retail markets where mergers were found to significantly impede competition, such as in the 2019 Carrefour-Promodes case in France.

Political and Electoral Implications

New Zealand First’s focus on grocery prices reflects a broader strategy to address cost-of-living concerns ahead of the election. The party, which polling suggests is competing for a threshold-crossing share of the vote, has positioned economic fairness and small business support as core pillars of its platform.

Analysts note that retail competition policy could resonate with voters in suburban and provincial areas where grocery costs are particularly salient. However, the feasibility of implementing structural change through electoral mandate remains uncertain, as any regulatory action would depend on the Commerce Commission’s independent assessment and potential legal challenges.

As of mid-April 2026, no other major party has formally adopted a policy to break up the supermarket duopoly, though several have acknowledged concerns about food pricing and market concentration in their policy discussions.
