The colony of New South Wales is founded. New South Wales, according to Arthur Phillip's amended Commission dated 25 April 1787, includes "all the islands adjacent in the Pacific Ocean" and running westward to the 135th meridian east. This included the islands of New Zealand. When drawing up the territorial boundaries of the colony of New South Wales, established in 1788, the British government set its western boundary at the meridian of 135° East of Greenwich, as it appeared on Melchisédech Thévenot's chart, Hollandia Nova‒‒Terre Australe, published in Relations de Divers Voyages Curieux (Paris, 1663).
The colony of New Zealand is proclaimed by Letters Patent. Although not represented on a map here, New South Wales was significantly reduced in size by this proclamation. Separation was effected on 3 May 1841.
