This beautiful shearwater breeds only on the Poor Knights Islands, a small group of islands off the eastern coast of Northland. They may be encountered in the northern hemisphere during their winter migration to the North Pacific on the west coast of North America. They return to New Zealand in September. We see them in the Hauraki Gulf, often on our trips to Tiritiri Matangi Island. We also see them occasionally on our pelagic trips off Kaikoura.
