Following the protests of Hori Te Whetuki on behalf of Ngāi Tai, in 1854 the Commission granted a "Native Reservation" of just over 6000 acres at Duders Beach (Umupuia) to "the chiefs of the Ngatitai" and paid them £500 compensation, on the condition that they sign an agreement to vacate all other lands within the original purchase boundaries, and order all other iwi to do the same.
