This report updates the CPUE analysis for the New Zealand surface longline fishery for swordfish, to be used in a revised stock assessment for the wider South Pacific region. Effective targeting of swordfish increased over time due to greater use of light-sticks, a concentration of fishing around the full moon and at night, and the legalisation of swordfish targeting in 2004.

A shore-based catch sampling programme for swordfish was developed and implemented which was cost-effective, statistically sound and achieved high coverage of landings. Individual processed weights were collected electronically from licensed fish receivers, and a predictive relationship was used to convert these to catch-at-length. Length-specific sex ratios derived from scientific observer data was projected onto the estimates of catch-at-length to estimate sex-specific catch-at-length.
