Description: While 9 species have been identified in New Zealand’s waters, this map includes haul out sites, colonies and breeding sites for 3 seals and sea lions: the southern elephant seal, New Zealand fur seal, and the New Zealand sea lion. All marine mammals including pinnipeds are protected under the Marine Mammal Protection Act of 1978, which requires people to stay at least 20 m from them and avoid disturbing or harming them. Pinnipeds experienced dramatic population declines coinciding with peak whaling activities in the early 1900s. Southern elephant seals (Mirounga leonine), the largest and deepest diving pinniped, are an Antarctic species which are found on subantarctic islands, where populations have been declining, and occasionally haul out on the mainland of New Zealand, though they are not currently thought to breed here. The New Zealand fur seal (Arctocephalus forsteri) is the most commonly encountered pinniped in New Zealand breeding at several locations on the mainland and subantarctic islands from mid-November to mid-January. The New Zealand, or Hooker’s sea lion (Phocarctos hookeri), is endemic to New Zealand with a small and declining population with main breeding colonies on Auckland and Campbell subantarctic islands as well as relatively new colonies in Stewart Island, Otago and Southland regions. Breeding occurs during the summer with pupping in early December through mid-January. Pups are dependent on their mother’s milk for a year and are often left alone on beaches while she feeds at sea. Foraging areas of pinnipeds can be large and are not well described around New Zealand’s waters. Harm by humans and dogs while onshore in addition to direct fishing mortality, declining food sources and pollution are major threats to pinniped populations. The locations included on this map are based on NABIS Fisheries Mapping Tool breeding colony datasets as well as communications with DOC experts.<div><br /></div><div>Haul out and breeding locations are subject to change and the most recent information for these areas should be confirmed in each region.
