Previously placed in genus Porzana. Closely related to Z. atra and †Z. monasa. Geographical variation slight, and validity of subspecies requires confirmation. Possible race plumbea (of S Australia and New Zealand) included in nominate tabuensis; various other proposed races (filipina, immaculata, oliveri, caledonica, vitiensis, tenebrosa) likewise synonymized with nominate. Three subspecies currently recognized.
