Population justification: In 2016 there were 126 individuals, including 109 breeding adults (A. Digby in litt. 2016).
Trend justification: The species was described as still abundant in Fiordland and some other parts of South Island in the early twentieth century. The current population comprises of at least 109 mature adults and 153 birds in total (A. Digby in litt. 2016), but although the population is now increasing, it has declined by >80% in the last 100 years (<3 generations) (P. Jansen in litt. 2004, D. Merton in litt. 2005, Merton 2009).
