A grocery duopoly: New Zealand supermarkets



The grocery retail market in New Zealand is worth billions of dollars each year and is one of the most concentrated supermarket sectors in the world. The industry is dominated by two large groups: Foodstuffs and Woolworths New Zealand. Together, these firms account for around 80–90 per cent of grocery sales, with Foodstuffs operating brands such as Pak’nSave, New World and Four Square, while Woolworths operates the Woolworths supermarket chain.

The market displays many of the characteristics of an oligopoly. The two dominant firms compete through store location, loyalty schemes, advertising and product range, and to some extent through pricing. At the same time, they benefit from substantial economies of scale, extensive distribution networks and strong relationships with suppliers. These factors mean that there are significant barriers to entry in the market and this can prevent new firms from entering the market and surviving.

Competition concerns

Concern about competition in the sector has led to investigations by New Zealand’s Commerce Commission. The Commission concluded that although there was competition in the market, it was less than optimal and both firms were earning higher profits than they would have been able to earn had they been in operating in a more competitive market.

It identified various barriers to entry that limited competition, including access to suitable retail sites, ownership of distribution networks and the difficulty of establishing large-scale supply chains in a country with a relatively small population.

Despite the market being dominated by these two big firms, there are also many smaller retailers operating within the market, including independent grocery stores, convenience stores and specialist food retailers. However, they lack the scale that is needed to challenge the dominance of Foodstuffs and Woolworths at a national level.

Potential international entrants, such as Aldi and Lidl, have often been suggested as possible competitors, but the costs of establishing a nationwide network of stores and distribution facilities in New Zealand are significant. There have been examples of large and dominant supermarkets in one country attempting to enter the market in other countries but failing to survive or deciding to exit the market early. For example, Tesco entered the Chinese market in 2004 but, despite its efforts, exited the market in 2020.

Response by the New Zealand government

In response to concerns about competition, the New Zealand government has introduced a series of measures designed to make market entry easier. These include restrictions on anti-competitive land covenants, the introduction of a Grocery Commissioner and changes intended to improve access to wholesale grocery supply.

But, despite these measures, recent reports suggest that the overall market structure has changed little, with the two major firms continuing to dominate grocery retailing.

The public interest

Supporters of the current market structure argue that large supermarket chains deliver lower costs through economies of scale and provide consumers with extensive product choice.

Critics counter that limited competition leads to higher prices, reduced innovation and weaker bargaining power for suppliers.

The debate illustrates the difficulties faced by policymakers when attempting to balance efficiency against the promotion of competition.

Whether greater competition will emerge in the future remains uncertain. Much will depend on whether existing reforms can encourage new entrants or whether the structural advantages enjoyed by Foodstuffs and Woolworths continue to deter potential rivals.

Competition policy – the evolving approach towards firms that misuse market power

The enforcement of Article 102 of the Treaty on the Functioning of the European Union (TFEU) by the European Commission (EC) tends to focus on exclusionary abuses by firms with significant market power. Exclusionary abuses are actions that limit or prevent competition, as opposed to exploitative abuses that directly harm the consumer, such as charging high prices.

The treatment of exclusionary abuses has evolved over time. Initially, the approach towards enforcement was form-based (i.e. the nature of the abuses), but this changed when the EC produced new guidelines in 2009 which signalled a move to a more effects-based approach.

The EC plans to produce a new set of guidelines in 2025 and published a draft version in August 2024 as part of the consultation process with businesses and other stakeholders. These draft guidelines indicate a partial shift back to a form-based approach. Any moves in this direction made by the EC are likely to influence both national-level competition authorities and the courts.

The form-based approach to policy enforcement

A form-based approach to the enforcement of Article 102 assumes that certain types of business conduct are inherently anti-competitive except in very exceptional circumstances. In other words, there is a presumption that the characteristics or form of the behaviour mean that it must have a negative impact on competition and consumer welfare in virtually all real-world cases.

With a form-based approach to enforcement there is no requirement for the authorities to carry out detailed case-specific analyses of business conduct as part of an investigation. This had been the approach adopted by the EC before 2009. It is possible, however, that the same form of business conduct could have anti-competitive effects in some market situations but pro-competitive effects in others. The EC was criticised for not making enough allowance for the chances of this happening.

The effects-based approach to policy enforcement

In response to this criticism the European Union published a new set of guidelines in 2009 which signalled that the enforcement of Article 102 was moving to a more effects-based approach. The effects-based approach uses economic analysis to assess the impact of a dominant firm’s conduct on a case-by-case basis. Context-specific evidence is examined by the competition authorities to see if the behaviour effectively excludes rival businesses from the market that are just as efficient as the dominant firm.

The use of economics in this effects-based approach gradually increased over time. Initially, the analysis was predominately based on theoretical arguments, but increasingly cases included sophisticated analysis of market-specific evidence using econometric models and market simulations. This, however, led to the following issues.

  • The increasing use of complex economic analysis makes it more difficult to meet the evidentiary standards of the courts and prove a case. As the effects-based approach places a greater burden on the competition authorities to meet these evidentiary standards (i.e. provide evidence of case-specific anti-competitive effects of the conduct) it disproportionality affects their ability to prove cases.
  • Businesses with significant market power are more likely to make large profits and so have access to greater resources than government-funded competition authorities. Therefore, they will be able to employ more economic consultants with the relevant technical expertise to (a) carry out the analysis and (b) communicate the findings effectively in a court case

This led to concerns that the competition authorities were losing cases where there was strong evidence of exclusionary conduct by the dominant firm.

In response to these concerns, the EC announced in 2023 that it would be revising its 2009 guidelines to improve enforcement of Article 102.

The draft guidelines

The draft guidelines published in August 2024 split different types of potentially anti-competitive conduct by dominant firms into three categories.

The first category includes types of conduct where there is a strong presumption of anti-competitive effects: i.e. the sole purpose of the business behaviour is to restrict competition. These types of conduct are referred to as a ‘naked restriction’ and the documentation provides the following three examples:

  • making payments to customers (typically other businesses) on the condition that they cancel or postpone the launch of a product that uses inputs produced by the dominant firm’s rivals;
  • threatening to withdraw discounts offered to suppliers unless they agree to supply the dominant firm’s product in place of a similar product produced by a rival firm;
  • actively dismantling infrastructure used by a rival firm.

The guidelines indicate a form-based approach will be taken when investigating these types of conduct as the EC will not have to provide any case-specific evidence of anti-competitive effects. A business under investigation can challenge the presumption of anti-competitive effects with appropriate evidence, but the guidelines make it clear that this would only succeed in exceptional circumstances. In other words, it is highly unlikely that the conduct could ever be justified on pro-competitive grounds.

The second category of anti-competitive conduct includes actions that are also presumed to have a negative impact on competition. The presumption, however, is not as strong as with naked restrictions, so firms have a better chance of proving pro-competitive effects.

There is a form-based element towards this second category of conduct as the EC will not have to provide any initial case specific evidence of anti-competitive effects. But, if a business under investigation does submit evidence to challenge the presumption of anti-competitive effects, the EC must demonstrate that (a) it has fully assessed this evidence and (b) the evidence is insufficient to prove that the conduct does have pro-competitive effects. As part of this process, the EC can provide its own case-specific evidence. Therefore, for this second category of conduct, the initial burden of proof effectively shifts from the competition authority to the firm under investigation, making it more of a form-based approach. However, if the firm uses relevant evidence to appeal its case, the burden shifts back to the competition authority and becomes a more effects-based approach.

The third category includes types of conduct where the EC must initially provide case-specific evidence that it reduces competition. For this category of conduct, the approach towards enforcement remains the same as in the 2009 guidelines and an effects-based approach is adopted.

It will be interesting to see the extent to which the final guidelines (a) follow the approach outlined in the draft guidance and (b) influence the enforcement of Article 102 by the EC and other national-level competition authorities.

Vetting vets

The Competition and Markets Authority (CMA) is proposing to launch a formal Market Investigation into anti-competitive practices in the UK’s £2bn veterinary industry (for pets rather than farm animals or horses). This follows a preliminary investigation which received 56 000 responses from pet owners and vet professionals. These responses reported huge rises in bills for treatment and medicines and corresponding rises in the cost of pet insurance.

At the same time there has been a large increase in concentration in the industry. In 2013, independent vet practices accounted for 89% of the market; today, they account for only around 40%. Over the past 10 years, some 1500 of the UK’s 5000 vet practices had been acquired by six of the largest corporate groups. In many parts of the country, competition is weak; in others, it is non-existent, with just one of these large companies having a monopoly of veterinary services.

This market power has given rise to a number of issues. The CMA identifies the following:

  • Of those practices checked, over 80% had no pricing information online, even for the most basic services. This makes is hard for pet owners to make decisions on treatment.
  • Pet owners potentially overpay for medicines, many of which can be bought online or over the counter in pharmacies at much lower prices, with the pet owners merely needing to know the correct dosage. When medicines require a prescription, often it is not made clear to the owners that they can take a prescription elsewhere, and owners end up paying high prices to buy medicines directly from the vet practice.
  • Even when there are several vet practices in a local area, they are often owned by the same company and hence there is no price competition. The corporate group often retains the original independent name when it acquires the practice and thus is is not clear to pet owners that ownership has changed. They may think there is local competition when there is not.
  • Often the corporate group provides the out-of-hours service, which tends to charge very high prices for emergency services. If there is initially an independent out-of-hours service provider, it may be driven out of business by the corporate owner of day-time services only referring pet owners to its own out-of-hours service.
  • The corporate owners may similarly provide other services, such as specialist referral centres, diagnostic labs, animal hospitals and crematoria. By referring pets only to those services owned by itself, this crowds out independents and provides a barrier to the entry of new independents into these parts of the industry.
  • Large corporate groups have the incentive to act in ways which may further reduce competition and choice and drive up their profits. They may, for example, invest in advanced equipment, allowing them to provide more sophisticated but high-cost treatment. Simpler, lower-cost treatments may not be offered to pet owners.
  • The higher prices in the industry have led to large rises in the cost of pet insurance. These higher insurance costs are made worse by vets steering owners with pet insurance to choosing more expensive treatments for their pets than those without insurance. The Association of British Insurers notes that there has been a large rise in claims attributable to an increasing provision of higher-cost treatments.
  • The industry suffers from acute staff shortages, which cuts down on the availability of services and allows practices to push up prices.
  • Regulation by the Royal College of Veterinary Surgeons (RCVS) is weak in the area of competition and pricing.

The CMA’s formal investigation will examine the structure of the veterinary industry and the behaviour of the firms in the industry. As the CMA states:

In a well-functioning market, we would expect a range of suppliers to be able to inform consumers of their services and, in turn, consumers would act on the information they receive.

Market failures in the veterinary industry

The CMA’s concerns suggest that the market is not sufficiently competitive, with vet companies holding significant market power. This leads to higher prices for a range of vet services. However, the CMA’s analysis suggests that market failures in the industry extend beyond the simple question of market power and lack of competition.

A crucial market failure is asymmetry of information. The veterinary companies have much better information than pet owners. This is a classic principal–agent problem. The agent, in this case the vet (or vet company), has much better information than the principal, in this case the pet owner. This information can be used to the interests of the vet company, with pet owners being persuaded to purchase more extensive and expensive treatments than they might otherwise choose if they were better informed.

The principal–agent problem also arises in the context of the dependant nature of pets. They are the ones receiving the treatment and, in this context, are the principals. Their owners are the ones acquiring the treatment for them and hence are the pets’ agents. The question is whether the owners will always do the best thing for their pets. This raises philosophical questions of animal rights and whether owners should be required to protect the interests of their pets.

Another information issue is the short-term perspective of many pet owners. They may purchase a young and healthy pet and assume that it will remain so. However, as the pet gets older, it is likely to face increasing health issues, with correspondingly increasing vet bills. But many owners do not consider such future bills when they purchase the pet. They suffer from what behavioural economists call ‘irrational exuberance’. Such exuberance may also occur when the owner of a sick pet is offered expensive treatment. They may over-optimistically assume that the treatment will be totally successful and that their pet will not need further treatment.

Vets cite another information asymmetry. This concerns the costs they face in providing treatment. Many owners are unaware of these costs – costs that include rent, business rates, heating and lighting, staff costs, equipment costs, consumables (such as syringes, dressings, surgical gowns, antiseptic and gloves), VAT, and so on. Many of these costs have risen substantially in recent months and are reflected in the prices pet owners are charged. With people experiencing free health care for themselves from the NHS (or other national provider), this may make them feel that the price of pet health care is excessive.

Then there is the issue of inequality. Pets provide great benefits to many owners and contribute to owners’ well-being. If people on low incomes cannot afford high vet bills, they may either have to forgo having a pet, with the benefits it brings, or incur high vet bills that they ill afford or simply go without treatment for their pets.

Finally, there are the external costs that arise when people abandon their pets with various health conditions. This has been a growing problem, with many people buying pets during lockdown when they worked from home, only to abandon them later when they have had to go back to the office or other workplace. The costs of treating or putting down such pets are born by charities or local authorities.

The CMA is consulting on its proposal to begin a formal Market Investigation. This closes on 11 April. If, in the light of its consultation, the Market Investigation goes ahead, the CMA will later report on its findings and may require the veterinary industry to adopt various measures. These could require vet groups to provide better information to owners, including what lower-cost treatments are available. But given the oligopolistic nature of the industry, it is unlikely to lead to significant reductions in vets bills.

The increasing use of dynamic pricing strategies

In September 2023, the Stonegate Group, the largest pub company in the UK with around 4,500 premises, announced that it was going to start increasing the pint of beer by 20p during busy periods. There was an immediate backlash on social media with many customers calling on people to boycott Stonegate’s pubs such as the Slug & Lettuce and Yates.

This announcement is an example of dynamic pricing, where firms with market power adjust prices relatively quickly in response to changing market conditions: i.e. to changes in demand and supply.

Traditionally, prices set by firms in most retail markets have been less flexible. They may eventually adjust to changing market conditions, but this could take weeks or even months. If a product proves to be popular on a particular day or time, firms have typically left the price unchanged with the item selling out and customers facing empty shelves. If the product is unpopular, then the firm is left with unsold stock.

One business that makes extensive use of dynamic pricing is Amazon. Prices for popular items on Amazon Marketplace change every 10 minutes and can fluctuate by more than 20 per cent in just one hour.

Conditions for dynamic pricing to operate

The Amazon example helps to illustrate the conditions that must be in place for a firm to implement dynamic pricing successfully. These include:

  • The capacity to collect and process large amounts of accurate real-time data on the demand for and supply of particular items i.e. the number of sales or the interest in the product.
  • The ability to adjust prices in a timely manner in response to changing market conditions indicated by the data.
  • Effectively communicating the potential advantages of the pricing strategy to consumers.

Consumer attitudes

The last point is an interesting one. As the Stonegate example illustrates, consumers tend to dislike dynamic pricing, especially when price rises reflect increases in demand. A previous article on this website discussed the unpopularity of dynamic pricing amongst fans in the ticket market for live musical events.

The precise reason for the increase in demand, can also have an impact on consumer attitudes. For example, following a mass shooting at a subway station in New York in April 2022, the authorities shut down the underground system. This led to a surge in demand for taxis and this was picked up by the algorithm/software used by Uber’s dynamic pricing system. Fares for Uber cars began to rise rapidly, and people started to post complaints on social media. Uber responded by disabling the dynamic pricing system and capping prices across the city. It also announced that it would refund customers who were charged higher prices after the subway system shut down.

There is a danger for businesses that if they fail to communicate the policy effectively, annoyed customers may respond by shopping elsewhere. However, if it is implemented successfully then it can help businesses to increase their revenue and may also have some advantages for consumers.

The growing popularity of dynamic pricing

It has been widely used in airline and hotel industries for many years. Robert Cross, who chairs a revenue management company predicts that ‘It will eventually be everywhere’.

More businesses in the UK appear to be using dynamic pricing. In a consumer confidence survey undertaken for Barclays in September 2023, 47 per cent of the respondents had noticed more examples of companies raising prices for goods/services in response to higher demand at peak times.

It has traditionally been more difficult for bricks-and-mortar retailers to implement dynamic pricing because of the costs of continually changing prices (so-called ‘menu costs’). However, this might change with the increasing use of electronic shelf labels.

It will be interesting to see if dynamic pricing becomes more widespread in the future or whether opposition from consumers limits its use.
