Abstract
 The 2020 stock assessment model of New Zealand red rock lobsters in CRA 4 fit to length-frequency data, sex ratio data, tag-recapture data, and standardised catch-per-unit-effort indices. Variable fishing mortality coupled with at least two major recruitment events since the 1990s has led to oscillations in the estimated population biomass, which is estimated to be at a low point in the cycle. The population is predicted to decline when current catch is projected five years.
