Observer data were used to assess the species composition of the New Zealand tuna longline fisheries and to estimate CPUE and the number of fish caught by observed vessels during 2015–16 to 2017−18 fishing years, and added this to the time series from 1989–90. Data were summarised by fishing fleet and area. Reported catches are presented. Discard practices and life status are summarised for the main non-target species.
