Quota Management System
New Zealand commercial fisheries are managed under the Quota Management System (QMS), introduced in 1986. Fishing is managed via a Total Allowable Commercial Catch (TACC) for each fish stock, which may not be exceeded. To go fishing, a commercial fisherman must own or lease quota, which is a set share of the TACC.
TACCs are reviewed and adjusted each year by the Minister for Primary Industries, based on the most recent fisheries stock assessment science and catch reports from the previous year. TACCs are set at a level to meet conservation needs and ensure healthy wild fish populations for future generations.
