The Ngāti Raukawa iwi confederation will present the next round of its treaty claims to the Waitangi Tribunal at Parewahawaha Marae in Bulls on November 9-13.
It will be the third week of hearings in a series that started in March this year.
Dennis Emery (Ngāti Kauwhata), chairman of Te Hono ki Raukawa Council, a main claimant group, said it is one of the last big Treaty claims in Aotearoa.
"The iwi comprise some 30,000 members and belong to Ngāti Raukawa ki te Tonga, Ngāti Kauwhata, Nga Iwi O Te Reureu, Ngāti Tūkorehe and Ngati Wehiwehi and are based in the Manawatū, Horowhenua and Kapiti Coast," Emery said.
"The main grievance and highly contentious issue is termed 'te pene raupatu' or land loss by the stealth of the pen for over 320,000 acres."
