Aorangi Kawiti, of Ngatiwai, countered that the TPP had already made a mockery of the Crown-Maori partnership.
"We were not consulted. We were not considered, and the thing was signed... How do you sleep at night?" she said.
Catherine Murupaenga, Ngati Kuri, also said the clauses meant little, given the Government interpreted the treaty as it suited.
"[Maori] are going to lose out because the Government controls that interpretation," she said.
Mr Finlayson responded saying interpretation issues would be dealt with through the courts, as they had been in the past. "[And] to suggest that because something is done with mandated negotiators behind closed doors, it's somehow secret and conspiratorial, I'm sorry, it's wrong," he said.
TPP opposition extended outside hui walls, where about 30 placard-wielding protesters gathered on Riverside Dr.
Among them, Paul Doherty said what could be done to stop the agreement being ratified remained "a good question", following its signing on February 4.
"The great thing that Maori are leading this resistance. They know what loss of sovereignty feels like," Mr Doherty said.
