This species is known from subfossil remains that were found during excavations on the island of Rapa, Austral Islands.
These remains somewhat fill the giant gap in the distribution area of the genus, which is found on the one hand with many species in the western Pacific region (New Caledonia and New Zealand faunal regions) and on the other hand with two species on the Society Islands in central Polynesia.
There are hundreds of suitable island groups and islands between these two areas where not a single member of the genus was ever found. [1]

The Rapa Parakeet very likely was a ground-dwelling species, like most members of its genus, and was also very likely very tame and thus was probably among the first birds to be eradicated by the first human occupants of the island. [1]
