The Australia–New Zealand Maritime Treaty is a 2004 treaty between Australia and New Zealand in which the two countries formally delimited the maritime boundary between the two countries.
The treaty was signed in Adelaide on 25 July 2004 by Foreign Minister of Australia Alexander Downer and Foreign Minister of New Zealand Phil Goff. It formalised the ocean borders that had been de facto recognised by both countries since the early 1980s, when the United Nations Convention on the Law of the Sea was created.
The treaty defines the boundaries between Australia and New Zealand's exclusive economic zones and continental shelf claims. Specifically, it defines two separate maritime boundaries, both of which are approximate median points between Australian and New Zealand territory. The two separate boundaries are not connected.
The first and more northern boundary separates the North Island and Three Kings Islands of New Zealand from Australia's Norfolk Island and Lord Howe Island. The northern boundary is composed of 27 individual straight-line segments defined by 28 separate coordinate points.
The second and more southern boundary defined by the treaty separates Australia's Macquarie Island from New Zealand's Auckland Island and Campbell Island. The southern boundary is composed of nine individual straight-line maritime segments defined by ten separate coordinate points.
