The Total Allowable Commercial Catch (TACC) is the maximum weight of a species of fish that can be taken by commercial fishers from a specified management area, in any one year. The TACC is specified in tonnes or kilos and is decided by the Minister of Fisheries every year. The TACC is shared amongst quota holders on a proportional basis, relative to how much quota each shareholder possesses.

The TACC is set by the Minister of Fisheries after the Total Allowable Catch (TAC) has been set, and after allowances have been set aside to provide for Māori customary fishing, recreational fishing, and for other mortality caused by fishing.
