Abstract
The main breeding population of packhorse rock lobster Jasus verreauxi around mainland New Zealand is in the extreme north, near Cape Reinga. Some larvae from this area (and possibly some from Australia) are carried southeastward in the East Auckland Current along the east coast of North Island, and settlement occurs as far south as Cook Strait. Recapture of tagged animals shows that most juveniles migrate toward Cape Reinga where they mature and breed. The single major breeding population and migratory pathway may mean that the species is particularly vulnerable to overfishing. New Zealand and Australian stocks may be linked by larval transport across the north Tasman Sea.
