Abstract
 A statistical model is proposed to estimate the catch efficiency (the proportion of fish biomass within the gear affected area that is retained by that fishing event) from catch-effort data for multiple fisheries and gear types operating simultaneously throughout the New Zealand EEZ. The model was applied to nine fish species to provide estimates of the catch efficiency for each species and gear type.
