Population justification: The Snares Islands population is c.410 pairs (Miskelly 2020), with the population of the translocated Putauhinu Island growing to an estimated 500 birds in early 2013. Translocated birds were confirmed breeding on Whenua Hou/Codfish Island in late 2012 (P. McClelland in litt. 2013), suggesting that the total population now numbers over 1,000 mature individuals. Given that the population is thought to be stable overall (Robertson et al. 2021), the population is estimated to be in the range 1,000-1,500 mature individuals.

Trend justification: The population has increased following successful translocations. Overall the population trend is considered to have been stable over the last three generations (Robertson et al. 2013, 2017, 2021).
