. It had three subspecies on each of the major islands of New Zealand, the North Island, South Island, and Stewart Island and nearby smaller islands. The species disappeared gradually after the introduction of invasive mammalian predators, last being seen on the North Island in 1955 and the South Island in 1968. Attempts were made to save the remaining population on small islands off Stewart Island, but they ultimately failed with the death of the last remaining known birds in 1972.

Taxonomy

German naturalist Johann Friedrich Gmelin described the bushwren in 1789.
