This species was found on the Chatham Islands, New Zealand, but was driven to extinction by the depredations of introduced species. The type material was collected in 1840, and it was Extinct by 1872.
|Range Description:||Gallirallus dieffenbachii was endemic to Chatham, Mangere and Pitt Islands, New Zealand (Marchant and Higgins 1993). It is known from the type, in Tring(Knox and Walters 1994), with one other specimen reported to be in Bremen (Greenway 1967), and from abundant subfossil material (Tennyson and Millener 1994). The species was already scarce when the type was collected in 1840, and was extinct by 1872 (Marchant and Higgins 1993).|
