Justification of Red List category
This species is listed as Critically Endangered because, subsequent to serious declines since the 1800s, it underwent a population crash following rat invasions in 1990-2000, and it now has a very small population that has declined during the last decade. However, the global population is now increasing owing to successful translocations onto four predator-free islands, and control of predators in its South Island range, and if this trend continues it may qualify for downlisting once the number of mature individuals in the population is clarified.

Population size: 50-249 mature individuals

Population trend: Decreasing

Distribution size (breeding/resident): 360 km2

Country endemic: Yes
