Justification of Red List category
Mainland populations of this species are declining by 1-2% per year because of poor recruitment due to predation of chicks, mainly by introduced stoats. The overall trajectory of the large Stewart Island population is unclear because the 2.2% per annum decline in the number of territories in the only study population, at Mason Bay, may be due to predation by introduced feral cats, or, more likely, to habitat change at that particular site. The overall decline of the species warrants Vulnerable status.
