Coastal k?whai (Sophora chathamica), sometimes known as Chatham Island k?whai, is one of 8 species of native sophora or k?whai in New Zealand and grows naturally in the north-west of the North Island in New Zealand, as far south as the Tongaporutu River in north Taranaki, and as far north as Te Paki. It can also be found growing near Wellington and the Chatham Islands, although these later plantings are thought to be a result of Maori plantings in the late 18th century and early 19th century. Prior to 2001, it was included as variant of Sophora microphylla, therefore references to either Sophora microphylla var. chathamica or Sophora microphylla subsp. microphylla var. chathamica are considered references to Coastal k?whai.
