Leigh Fisheries Ltd is the first fishery in New Zealand to be certified sustainable by Friend of the Sea.

Most of the species caught by Leigh Fisheries Ltd are officially recognized as sustainable, including New Zealand Red Snapper, Alfonsino, Red Gurnard, Grouper, Bass, John Dory, Kingfish, Ling, Snapper, Swordfish, Trevally and Spiny Rock Lobster.

In keeping with New Zealand's strict quota management system to prevent overfishing, Leigh Fisheries Ltd products are caught to order which ensures no waste and avoids the unnecessary capture of juvenile and older fish. This falls in line with part of the criteria Friend of the Sea uses for certification.

Leigh Fisheries Ltd is traded worldwide by the Lee Fish Group with companies in America, Europe and Asia.
