Hāmuera (Samuel) Taumaru signed Te Tiriti at Tāwhirihoe on 21 May 1840. He was the first clergyman at Parewanui (the old church is still there).
A local historian described Hāmuera as an educated and aristocratic man with a gentle disposition. He and his wife Ria raised Tahupōtiki Wiremu Rātana, the founder of the Rātana movement. Hāmuera was a missionary-educated teacher who, at the time of the Treaty, moved frequently between Ōroua and Rangitīkei.
In the Native Land Court in 1868, he said that Henry Williams had not told him what the Treaty was about when he signed it.
