, 1869,

small rocky islet off Chatham Island

.

Closely related to and sometimes considered conspecific with †C. iredalei, C. huegeli and C. aucklandica, but differs from them in its much smaller size (effect size for male bill difference 6.63; score 3); somewhat coarser breast streaking than in morphologically closest nominate aucklandica (1); apparently (fide published sonagrams#R) different song structure (accelerating where aucklandica does not) and calls (at least 3). Monotypic.
