What did Hobson’s sovereignty proclamations actually do?
The 21 May 1840 proclamations are Crown acts asserting sovereignty. They are central to the Crown legal chain, but an assertion made by the Crown is not the same evidential category as consent given by rangatira.
On 21 May 1840 William Hobson issued proclamations declaring British sovereignty over New Zealand. For the North Island, the proclamation recited the Treaty of 6 February and asserted that sovereignty had been ceded. For the southern islands, Hobson relied on a different Crown theory: discovery.
The North Island proclamation went further than merely announcing an intention. It declared that full sovereignty vested in Queen Victoria and her heirs and successors. The proclamation therefore operates inside the British legal narrative as a formal executive assertion of the Crown's territorial authority.
Timing matters too. Treaty signatures were still being collected after 21 May. The Crown therefore proclaimed sovereignty over the whole country before the signing process had finished.
What this instrument establishes
A dated Crown act; the Crown's stated legal basis; the territorial scope of the assertion; and the point at which Crown officials began treating sovereignty as formally proclaimed.
What it does not independently establish
That the Māori text of Te Tiriti conveyed the same thing Hobson's proclamation said had been ceded, or that every political community had authorised the Crown to make that declaration.
The proclamation is therefore a bridge in the Crown's legal chain, but it is evidence of assertion first. The next question is how that assertion was converted into a functioning colonial governmental structure.
