Kāwhia, 3 September 1840

The last signature to be added to the Manukau-Kāwhia treaty sheet was that of Wharekawa, who may have been from Whakatīwai in Waikato. He signed with a cross next to his name on 3 September 1840, presumably with Wesleyan (Methodist) missionaries James Wallis and John Whiteley present, though they did not witness his signature. A letter from Police Magistrate W.C. Symonds to Whiteley, dated 8 April, shows that Symonds sent the Manukau-Kāwhia sheet and some blankets (as gifts for signatories) to these missionaries and instructed them to collect signatures from Ngāti Maniapoto as far south as possible.

The addition of this signature made agreement to the treaty on the west coast of the North Island almost unanimous as far south as Mōkau. This copy of the treaty was then supposed to be sent to Taranaki, but Whiteley argued that because Taranaki was considered a conquered territory, the agreement of Waikato (‘the conquerors’) would cover this area. The Manukau-Kāwhia copy of the treaty was sent back to Lieutenant-Governor William Hobson, but because it was not sent on to the Colonial Office until 26 May 1841, its signatures were not included in the then-stated total of 512.
