Taxonomic note

Coenocorypha aucklandica, C. huegeli, C. barrierensis and C. iredalei (del Hoyo and Collar 2014) were previously lumped as C. aucklandica following Sibley and Monroe (1990, 1993).

Population justification: The species is considered extinct.

Trend justification: Populations on South Island and on Stewart Island were most likely extirpated following the introduction of Pacific Rat Rattus exulans with the Maori (Miskelly 2013). On Jacky Lee Island, naturalists recorded the species between 1897 and 1911, when only a single bird was found: none could be found in 1928 (Miskelly 2013). On Taukihepa, five pairs were known in November 1923 and five nests were located in 8 days in December 1931 (Miskelly 2013). Efforts to capture birds by the Wildlife Service in August/September 1964 following the introduction of black rats Rattus rattus obtained two males, but both died in captivity shortly afterwards (Miskelly 2012, 2013). The species is believed to have gone extinct sometime since 1964 (Szabo et al. 2012), as these were the last two records of the species.
