Range DescriptionNew Zealand Sea Lions have a highly restricted distribution for a marine mammal. Their primary habitat is several subantarctic islands south of New Zealand, and their surrounding waters. The principal breeding colony is at the Auckland Islands, with the most of the remaining animals breeding at Campbell Island (Maloney et al. 2012). New Zealand Sea Lions regularly occur in small numbers at Stewart Island and on the southeast coast of the South Island of New Zealand, where there are some births (McConkey et al. 2002). However, most of the animals hauling out on the South Island are males ranging in age from 2 to 11 years old. Wandering New Zealand Sea Lions also reach Macquarie Island. Before human occupation (Maori and European), New Zealand Sea Lions had a more extensive range that appears to have included most of the New Zealand mainland and subantarctic islands. Polynesian midden records show pup and adult bones from the top of the North Island, through the South Island and into the subantarctic islands of New Zealand (Childerhouse and Gales 1998).
