Range Description

C. aucklandica is endemic to New Zealand, where it is found on the Auckland Islands (excluding the main island; nominate C. a. aucklandica), the Antipodes Islands (20 km2) (form meinertzhagenae) and Jacquemart Island (0.2 km2) in the Campbell Island group (form perseverance). C. a. perseverance was not known to exist before a chance discovery on Jacquemart Island in 1997, but has since recolonised the main Campbell Island from Jacquemart Island following the eradication of Norway rats in 2001, and is now rapidly spreading over the 12,300 ha island (Miskelly 2013, P. McClelland in litt. 2013).
