The New Zealand quail (''Coturnix novaezelandiae''), or ''koreke'' (the Māori name), has been extinct since 1875. The male and female were similar, except the female was lighter. The first scientist to describe it was Sir Joseph Banks when he visited New Zealand on James Cook's first voyage. Terrestrial and temperate, this species inhabited lowland tussock grassland and open fernlands.〔(), Pappas, J. 2002. "Coturnix novaezelandiae", Animal Diversity Web.〕 The first specimen to be obtained by a European was collected in 1827 by Jean René Constant Quoy and Joseph Paul Gaimard on Dumont D'Urville's voyage. Research was conducted between 2007 and 2009 into whether the quails on Tiritiri Matangi Island – which was spared the worst impact of introduced predators – might be a surviving population of this species, or ''koreke''-brown quail (''Coturnix ypsilophora'') hybrids.〔(NZ quail may not be extinct say scientists after Haurauki Gulf island discovery ), ''Massey News'', 24 March 2007.〕 However, a genetic study showed instead that the quail on Tiritiri Matangi are Australian brown quail, ''Coturnix ypsilophora''.〔(Scientists nail quail mystery — Tiri quails found to be Aussie imports ), ''Massey News'', 23 October 2009.〕 Sequences were derived for all quail species within the Australian and New Zealand ''Coturnix sp''. complex.〔Seabrook-Davison, M.; Huynen, L.; Lambert, D.M.; and Brunton D.H. (2009). Ancient DNA Resolves Identity and Phylogeny of New Zealand's Extinct and Living Quail (Coturnix sp.). ''PLoS ONE'' 4(7), e6400. A neighbour-joining phylogenetic distance tree was constructed in PAUP4 with 1000 bootstrap replications to determine the strength of groupings. The sequences used for the tree were derived from 3 separate mitochondrial control region sequences..〕 It has sometimes been considered conspecific with the Australian stubble quail ''Coturnix pectoralis'', which would then be named ''Coturnix novaezelandiae pectoralis'' as the New Zealand bird was described first. However, the genetic analysis showed that they are separate though closely related species.〔Seabrook-Davison, M.; Huynen, L.; Lambert, D.M.; and Brunton D.H. (2009).
