New Zealand Sea Lions have a highly restricted distribution and a small population that numbers approximately 11,855 animals (Campbell et al. 2006). This equates to an adult population size of <10,000. Pup production has shown a decline of 30% in the last 10 years, but this was preceded by a few years of growth. Data from one of the main colonies shows no overall trend in pup production over the past 25 years (Chilvers et al. 2007).
