Abstract
 This project updated the fishery characterisation and CPUE standardisations for school shark in New Zealand, including size-frequency information. Trends in standardised CPUE differed across regions and sometimes across gears in the same region. New bottom trawl indices did not resolve the ongoing conflict in set-net and bottom-longline CPUE in SCH 2 & top of SCH 3. Trawl survey indices were accepted as index of abundance for SCH 7, SCH 8 & lower SCH 1W given declining set net effort.
