Population justification: The total population was estimated to be 19,000-26,000 breeding pairs (Moore and Moffat 1990, Sagar 2014), with the most recent censuses in 2006-2012 giving an estimate of 21,648 pairs (Sagar 2014).

Trend justification: Numbers decreased steeply in the 1970s and 1980s, attributed to bycatch longline fisheries. One colony declined at a rate of 5.9% per year between 1966 and 1981, and 10.5% per year between 1981 and 1984, equating to an overall population reduction of 72% during that period. However, numbers have been either stable or increasing slightly since 1984 (Waugh et al. 1999a), with a 1.8% increase recorded in selected colonies between 1992 and 1997 (Moore 2004), although the last census was in 1996/7. The trend over the past three generations (85 years) is assumed to be negative, but, based on the decrease in fishing effort following a peak in 1971-1983, the population is considered likely to continue to expand.
