Moturoa is a steeply sloped island off the coast of Taranaki, New Zealand.

It is separated from the Taranaki coast of the North Island mainland by an 800-metre (2,600 ft) wide channel.

[2] The island has lent its name to Moturoa, a suburb of New Plymouth, which lies on the mainland 1.5 kilometres to the southeast.

Moturoa is uninhabited, but it and several of the other Sugar Loaf Islands were hunting, fishing and gathering grounds and places of refuge for local inhabitants and the Taranaki and Te Āti Awa for hundreds of years.

After this was abandoned focus turned to mining Paritutu, west of New Plymouth.
