"We need a level playing field where all Te Hiku iwi can participate fairly," he said.
Key evidence submitted by Te Rarawa had already been rejected by the tribunal, and iwi representatives had been required to sit in a tent outside last week's hearing at Kareponia, so had been unable to properly engage in the korero and proceedings.
"The unbalanced format used by Ngati Kahu organisers has not worked for Te Rarawa over the last four days," Mr Piripi added.
"The Te Rarawa negotiation team also has the responsibility to preserve the essence of the currently agreed and ratified Te Rarawa deed of settlement, and the filing of this application will achieve that."
He did not expect the new proceedings to necessarily delay Te Rarawa's settlement, saying that if anything the application would provide further surety for and enhancement of the agreed redress.
