Population justification:

The population is estimated to number a minimum of 3,000 mature individuals, assumed to equate to a total population of over 4,500 individuals, based on an estimated minimum of 3,000 mature individuals from distance sampling on Little Barrier (Department of Conservation unpublished report 2012, per J. Ewen, K. Richardson and P. Brekke in litt. 2012). Population estimates from each translocated population in 2011/2012 sum to c.430 adults (Department of Conservation unpublished reports 2012), but these are not counted in the total since it is uncertain how many translocated birds have bred successfully in the wild and can therefore be counted as mature individuals sensu IUCN.

Trend justification: No comprehensive surveys have estimated population trends on Little Barrier, where the only natural and self-sustaining population remains. However, it is not thought to be in decline there, although confirmation is needed.
