The length and age of trevally in TRE 1 and 2 was investigated by sampling bottom trawl (BT) and Modular Harvest System (MHS) landings between 2017 and 2020. East Northland/Hauraki Gulf had small and young trevally, but older fish have become more common. Bay of Plenty had an increasing proportion of large and old trevally. TRE 2 was dominated by small and young fish. The level of precision achieved was marginally acceptable. BT may have a higher selectivity for small trevally compared to MHS.
