Auckland Islands. The first collected specimen, incorrectly identified by von Hugel in 1875 as Rallus brachipus Swainson, 1838 (= R. pectoralis Temminck), is now in the American Museum of Natural History (Oliver 1955: 351). Otherwise known until recently only from this and the type specimen (now missing, presumed destroyed) and a live bird collected on Adams Island in 1966 (Falla 1967). In 1989 the rail was found on Adams Island in good numbers. Previously listed as Rallus pectoralis muelleri (e.g. Checklist Committee 1990) or Dryolimnas pectoralis muelleri (e.g. Marchant & Higgins 1993), we follow Sibley & Monroe (1990) and Taylor & van Perlo (1998) in placing this taxon in Lewinia. .
