The Treaty of Waitangi, concluded between many Māori chiefs and the British Crown in 1840, is the foundational testament of Aotearoa New Zealand. Despite the constitutional character, its status, subject matter, and terms of the treaty are disputable. Legal positivists deny the validity of the treaty; the English text, but not the Māori version, supports cession of sovereignty despite the Māori probably not sharing the European conception of sovereignty. Such ambiguities and paradoxes obstruct categorical conclusions being drawn about sovereignty and the treaty. This article destabilizes and remystifies the positivist conception of Crown (state) sovereignty, rather than establishing illusory certainties about sovereignty in Aotearoa New Zealand. Stripped of its positivist certainties, sovereignty, on a day-to-day basis, may be seen to concern the ways self-determining peoples protect, preserve, and develop their cultures. Viewed in this light, sovereignty in Aotearoa New Zealand cannot plausibly be claimed by one particular culture; therefore, other solutions must be considered. [sovereignty, Treaty of Waitangi, Aotearoa New Zealand, Indigenous constitutions] If the treaty were void, a radical view might hold that the Crown has no legal grounds for its presence in New Zealand. In fact, those who claim the treaty is a nullity argue that the territory was not acquired by cession "but rather by occupation of "vacant" territory and the assertion of sovereignty by certain acts of state" (Joseph 2001:49). Patently, Aotearoa was not terra nullius (unoccupied land), and acts of state by the Crown were possible because the Māori generally did not resist them; it may be inferred they did not resist alien governance because they had concluded the treaty in good faith. Furthermore, in the early colonial period and again in recent decades, the Crown has recognized the validity of the treaty.
