Abstract Annual growth, growth per moult, moult frequency, and moulting seasons were estimated for rock lobsters Jasus edwardsii tagged in three areas around Stewart Island. There were no significant differences in growth parameters between the areas within the size range 70-99 mm carapace length, although differences between Stewart Island and previously reported data from Gisborne were noted. There were significant differences in growth between the sexes. Females reached minimum legal size at about 6 years and sexual maturity at about 8 years after settlement. Males reached minimum legal size at just under 6 years.
