From Wikipedia, The Ross Dependency is described as a region of Antarctica, defined by a sector originating at the South Pole, passing along longitudes 160° east to 150° west, and terminating at latitude 60° south.

Despite The Antarctic Treaty was brought to bear in 1961 which states countries do not recognise territorial claims, New Zealand has maintained its claim on this particular region of Antarctica.

The Dependency takes its name from Sir James Clark Ross, who discovered the Ross Sea, and includes part of Victoria Land, and most of the Ross Ice Shelf. Ross Island, Balleny Islands and the small Scott Island also form part of the Dependency, as does the ice-covered Roosevelt Island.

New Zealand Post issues stamps covering this region, many of which are quite attractive in design.
