Population justification:
The estimated annual breeding population is 32,134 pairs, made up of 8,704 pairs on the Snares Islands, 5,280 pairs on the Solander Islands, 16,000 pairs on the Forty-Fours, 2,130 pairs on Big and Little Sister Islands in the Chatham Island group, and 20 pairs on Rosemary Rock, Three Kings Islands off North Island.
Trend justification:
The Snares Islands population has almost doubled since 1969, but the rate of increase slowed in the 1990s and then became stable 2002-2014 (Sagar et al. 1999b, Sagar and Stahl 2005, Sagar 2014). The Solander Islands population appears to have remained relatively stable during 1985-1996, and increased by around 1.36% /annum during 1996-2016 (Sagar and Stahl 2005, Thompson et al. 2016).
