Petroica longipes; Print; The North Island robin (Petroica longipes) is a species of Australasian robin endemic to the North Island of New Zealand. It and the South Island robin (P. australis) of the South Island and Stewart Island were once considered conspecific (and called the "New Zealand robin"); but mitochondrial DNA sequences have shown that the two lineages split prior to the Pleistocene and support the classification as two different species.; 1825-1838
