Abstract
A SEFRA model was developed for female New Zealand sea lions at the Auckland Islands. Inputs to the model included: the estimated at-sea spatial density of female sea lions, and cryptic mortality priors relating to SLED use. Across the last 3 years assessed, the estimated annual risk ratio across all Auckland Islands fisheries was 0.24 (95% credible interval (CI) = 0.11–0.47); consistent with population recovery to 97.5% of unimpacted status when assuming deaths at the upper 95% CI level.
