Population justification:

The population has been estimated at c.5,500-7,000 mature individuals (Mattern 2013, Long 2014). Due to the cryptic breeding habit and resulting difficulty of surveying the species, this number is likely to be an underestimate (Mattern 2013). At some sites numbers appear to have declined, while slightly increasing numbers have been reported from others making it difficult to identify clear species-wide population trends (Mattern 2013). At Open Bay Island, there was a decline of 33% between 1988 and 1995 (Ellis et al. 1998), and at Dusky Sound there were anecdotal reports of thousands of birds in 1900, but only a few hundred remained in the 1990s (Russ et al. 1992).

Trend justification: Introduced predators, human disturbance and accidental deaths caused by fisheries are all contributing to an on-going decline in this species's population. Recent historical counts used unstandardised methods and results are hard to interpret, so further research is urgently needed.
