This report summarises a stock assessment of ling on the Chatham Rise (LIN 3&4) for the 2021–22 fishing year. The main index of abundance was the trawl survey series as the commercial longline standardised catch per unit effort series was not deemed suitable. The initial biomass was similar to the previous assessment at about 110 040 t; stock status in 2021 was estimated at 56% B0. Projected stock status in 2027 was between 46% and 59% of B0 depending on recruitment and catch assumptions.
