Foodstuffs, officially Foodstuffs (NZ) Ltd is a group of two New Zealand grocery and liquor retailers' cooperatives based in the North Island and the South Island which collectively control an estimated 52% of the New Zealand grocery market. The group owns retail franchises 4 Square, New World and Pak'nSave, in-store private labels Pam's and Budget, and a ten percent stake in The Warehouse.[1] The effective duopoly in New Zealand's supermarket industry[2] means that Foodstuffs' only real competitor is Australian supermarket chain Progressive Enterprises.
