Population justification: In 1975, the population was estimated at c.2,000 pairs or 8,000 birds (Marchant and Higgins 1990, Heather and Robertson 1997). However, the breeding season may be quite prolonged and staggered between colonies, and therefore the census may have underestimated numbers (P. Moore in litt. 1999), so the number of individuals may be a more reasonable reflection of the breeding population. Nevertheless, a more up-to-date population estimate is required for this species.
Trend justification: In the absence of significant known threats, this species's population is suspected to be stable.
