The known geographical distributions of the genus Astrostole and the New Zealand species A. scabra are modified extensively by new records presented here. The supposed dispersal agency, West Wind Drift, is shown to have been incapable of producing the present pattern, and interaction, between a west to east current north of the sub-tropical convergence, an eastern Pacific surface gyre and the Peru Coastal Current is suggested as the dispersal mechanism.
