Abstract Growth rates of three species of abalone in New Zealand were estimated by fitting data to the von Bertalanffy growth equation. Length-frequency analysis and tagging were used for Haliotis iris Martyn, and shell growth-checks were used for H. australis Gmelin and H. virginea Gmelin. The relative growth coefficient (K) and the asymptotic length (Leo) were found to be 0.3104 and 146.2 mm respectively for H. iris, 0.3205 and 86.75 mm for H. australis, 0.4460 and 61.5 mm, and 0.3231 and 64.4 mm for H. virginea from two separate localities. An absolute growth curve could be calculated only for Haliotis iris.
