Dog Island (Motu Piu in Māori) is located in Foveaux Strait some 5 kilometres (3.1 mi) from Bluff, New Zealand.

[1] Dog Island is low-lying and rocky, and its highest (natural) point is about 15 metres (49 ft) above sea level.

[10] Due to its remote location, children could not attend school on the mainland, and supplies arrived by ship every three months.

[7][8] A Dog Island Motu Piu Charitable Trust has formed to work on heritage preservation and public education.

[11] Sarah Dowie, Member of Parliament for the Invercargill electorate, is the current deputy chair of the trust.
