Mataitai
Mataitai reserves are created in areas of traditional importance to Maori for customary food gathering. Within them, tangata whenua are authorised by the Minister of Fisheries to manage and control the non-commercial harvest of seafood through a local committee.

Shellfish gathering
A tangata tiaki/kaitiaki can recommend bylaws to manage customary food gathering in keeping with local sustainable management practices, and issue customary food authorisations.
Mataitai reserves are permanent, though the bylaws can change over time. Once a mataitai reserve is established, commercial fishing is not allowed unless recommended by the tangata tiaki/kaitiaki. Maori and non-Maori may fish in mataitai reserves.
