Abstract
 The total species population size estimate of New Zealand sea lion/pakake/whakahao was updated using the available demographic and population size information up to 2022 (the 2021–22 breeding season). All analyses were conducted within a Bayesian estimation framework, and the posterior total population size estimate was approximately 10 000 individuals in 2022 (median: 10 151; 95% credible interval: 8702–12 082 individuals), slightly below the estimate for 2015 using the same method.
