#national: Consumer NZ Raises Alarm Over Supermarket Pricing as Food Costs Surge

Download AudioConsumer NZ is warning that food prices in Aotearoa may be reaching excessive levels, with growing concern that entrenched market power within the supermarket sector is leaving consumers exposed to sustained and, in some cases, unjustified increases.
Head of research and advocacy Gemma Rasmussen says the organisation is seeing clear patterns in pricing behaviour that suggest more than just global inflationary pressure is at play. Reports of inconsistent pricing, questionable discounting practices and significant mark-ups on everyday essentials are becoming increasingly common, with concerns that some promotions may not represent genuine savings.
The warning comes as the cost of basic items, including fresh fruit and vegetables, continues to climb sharply. While global factors such as fuel prices and supply chain disruptions are contributing to higher costs, Consumer NZ says the scale and consistency of price increases point to deeper structural issues within the domestic market.
New Zealand’s supermarket sector remains dominated by two major players, and that lack of competition is being identified as a key factor in sustained high prices. Despite repeated scrutiny and earlier interventions, including the establishment of a Grocery Commissioner, there are ongoing questions about whether current regulatory settings are strong enough to influence behaviour or deliver meaningful price relief.
Consumer complaints have also highlighted concerns around misleading specials, with shoppers reporting instances where discounts appear inflated or unclear. These practices are contributing to a growing sense of distrust, as consumers struggle to determine whether they are receiving fair value at the checkout.
The continued profitability of major supermarket chains, even as households face mounting cost pressures, is adding to calls for more decisive action. Consumer NZ is signalling that incremental changes may no longer be sufficient, and that stronger regulatory tools could be required to address pricing transparency, competition and market conduct.
Potential measures being discussed include tighter oversight of pricing practices, clearer rules around promotional activity, and interventions aimed at increasing competition within the sector. There is also growing pressure on the Grocery Commissioner to take a more assertive role in monitoring and enforcing fair conduct.
With fuel prices and other global pressures expected to remain volatile, the risk is that supermarket costs will continue to rise, further impacting household budgets. For many whānau, the cost of putting food on the table is becoming increasingly difficult to manage.
As scrutiny intensifies, the focus is shifting toward ensuring that any price increases are justified, transparent and fair, and that consumers are protected in a market where choice remains limited.
