 A commercial catch sampling design was developed for estimating the age-structure of hāpuku (Polyprion oxygeneios) from the New Zealand bottom longline fishery. Based on the minimum required number of otoliths, current catches, and market conditions, there may be potential for a catch sampling project in HPB 1, HPB 2, HPB 4, and HPB 5, but this would generally incur a high cost and require highly targeted sampling as well as a high degree of cooperation with fishers and licensed fish receivers.
