The present study provides estimates of seabird bycatch in commercial fisheries in New Zealand waters. Estimates were derived using statistical models that integrated fishing effort and observer data up to the 2017–18 fishing year. In 2017–18, there were 3328 (95% credible interval, c.i.: 2971–3782) estimated seabird captures, including 1506 (95% c.i.: 1344–1696) captures in trawl, and 1186 (95% c.i.: 913–1589) and 635 (95% c.i.: 536–758) captures in bottom and surface longline, respectively.
