Justification of Red List category

This species is classified as Vulnerable because it has a very small range (a single remnant population on 28 km² Hauturu/Little Barrier island) such that it is susceptible to stochastic events and the impacts of human activities. The plausible threat of introduced predators could drive the species to Critically Endangered or Extinct in a very short time period. Intensive conservation efforts aim to improve its status, but these have resulted in only partial success with translocated populations requiring intensive and ongoing management.

Population size: 2500-3400, 3100 mature individuals

Population trend: stable

Extent of occurrence (breeding/resident): 48 km²

Country endemic: yes
