Justification of Red List category
This species is listed as Endangered because it has a very small, albeit increasing, wild population. Although the total number of mature individuals in New Zealand is now considerably larger than 250, large numbers of these are in intensively managed subpopulations and/or are located on small islands or 'mainland islands' that are too small to support self-sustaining populations, so they are not treated as wild individuals in this assessment. A re-introduced population at Kahurangi National Park has not yet been established for five years and so it is also excluded from this assessment. If the wild population continues to increase, the species will warrant downlisting to Vulnerable in due course.
