Kāwhia, 27 August 1840

The twelfth signature gained for the Treaty of Waitangi in Kāwhia was from Ngāmotu, a rangatira who may have been from Ngāti Maniapoto. This signature is not specifically witnessed, but is part of the series of signatures that were obtained in Kāwhia by the local Wesleyan (Methodist) missionaries, James Wallis and John Whiteley.

They had been sent the Manukau-Kāwhia treaty sheet on 8 April by W. C. Symonds, a recently appointed police magistrate who had been charged with collecting signatures in the Manukau and Waikato regions. As news of the gifts given at Waitangi and Hokianga had preceded the arrival of the treaty in this region, blankets were also sent to the missionaries to be distributed as gifts to the signatories. Symonds made it clear in his instructions that the blankets should not be construed as bribes or payment for signatures. Wallis and Whiteley carried out their task of securing signatures in Kāwhia for several months, gaining signatures on six different occasions over this period.
