June 2026 grocery report found major supermarkets retained over 80% of the market
A look back at the Commerce Commission’s 2 June 2026 update on competition and the growth of smaller grocery retailers.

What the Commission reported in June
The Commerce Commission released its third Annual Grocery Report on 2 June 2026. It said the major supermarkets retained more than 80% of the national retail market.
The report primarily covered the 2025 financial year. The Commission described margins and profitability as relatively flat, alongside higher retail prices. These are findings from that reporting period.[1]
Smaller retailers were expanding
The Commission also reported new stores and expanding specialty grocers, particularly in Auckland. It said some greengrocers and butchers were broadening their ranges.
That helps explain why a useful price comparison may include retailers beyond the major supermarket chains. It does not establish that every smaller retailer has a lower price.[1]
