Longline catch effort data targeting snapper or hapuku/bass/bluenose were used to evaluate alternative longline survey designs, to monitor changes in the abundance. Commercial longline skippers were interviewed to identify commonly used gear configurations that could be used for a survey, and to understand factors that might affect catch rates. A longline survey could be used to monitor the SNA 1 stock, a catch sampling monitoring approach appears more feasible for the hapuku/bass.
