The treaty was written at a time when the New Zealand Company, acting on behalf of large numbers of settlers and would-be settlers, were establishing a colony in New Zealand, and when some Māori leaders had petitioned the British for protection against French incursions. It was drafted with the intention of establishing a British Governor of New Zealand, recognising Māori ownership of their lands, forests and other possessions, and giving Māori the rights of British subjects. It was intended by the British Crown to ensure that when Lieutenant Governor William Hobson subsequently made the declaration of British sovereignty over New Zealand in May 1840, the Māori people would not feel that their rights had been ignored. Once it had been written and translated, it was first signed by Northern Māori leaders at Waitangi. Copies were subsequently taken around New Zealand and over the following months many other chiefs signed. Around 530 to 540 Māori, at least 13 of them women, signed the Māori language version of the Treaty of Waitangi, despite some Māori leaders cautioning against it. An immediate result of the treaty was that Queen Victoria's government gained the sole right to purchase land. In total there are nine signed copies of the Treaty of Waitangi, including the sheet signed on 6 February 1840 at Waitangi.
