Cyanoramphus cookii is endemic to Norfolk Island (to Australia). It was once found throughout the island, and estimated to number at least 190 pairs. It is now confined to the Norfolk Island National Park and adjacent forested areas and orchards (Hill 2002). In 1994, the declining population consisted of only four breeding females and 28-33 males. Conservation management measures have allowed the population to grow, and numbers were estimated at a possible 200-300 individuals in 2004, and 150-200 birds in 2008. However, recent observations of disappearance from places where it was once common, and eviÂdence of cat predation (M. Christian, R. Ward and J. Forshaw pers. comm., in Garnett et al. 2011) suggest the population may be declining again.
