The Ross Dependency is 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. New Zealand`s claim to the region was formalized in 1923, when the Governor-General of New Zealand was appointed as the Governor of the Ross Dependency by an Imperial Order in Council made in London, United Kingdom. Since the Antarctic Treaty came into force in 1961, Article 1 of which states "The treaty does not recognize, dispute, nor establish territorial sovereignty claims; no new claims shall be asserted while the treaty is in force", most countries do not recognise territorial claims in Antarctica.
