South Waikato iwi Ngati Raukawa has resolved disputes with neighbouring tribes on overlapping land claims - clearing the way to sign a Deed of Settlement.
Raukawa and the Crown are due to sign the deed on Saturday at Aotearoa Marae in Te Awamutu.
To reach this stage, the Raukawa Settlement Trust has been working directly with neighbouring tribes, such as Tuwharetoa, Te Arawa and Ngati Maniapoto.
As a last resort, tribes were able to call for help from the Waitangi Tribunal.
Lead treaty negotiator for Raukawa Vanessa Eparaima says the tribunal was called in.
She says neighbours' concerns covered a diverse range of issues, but she is happy they have been resolved.
Ms Eparaima says one issue dealt with was the situation of Raukawa and one of its neighbours being able to both claim ties to a piece of land by using the name of a tipuna, or ancestor, to whom they are related.
