Mr Henare, who spent six years as the chairman of the Maori Affairs Select Committee, said Ms Hickey's cross-examination should not have been allowed to drag on for almost five hours. He claimed "at least 50 per cent" of the lawyers' questions were irrelevant or statements dressed up as questions.
If time had been managed properly everyone could have been heard, he said. The Tribunal declined to comment on Mr Henare's concerns.
The view he would have put to the Tribunal was that Ngapuhi should pursue a single settlement, with mechanisms put in place to respect the mana of hapu involved.
"We should be in there, boots and all, getting as much as we can from the Crown. Why should people die waiting?" he asked.
Former Ministry of Maori Affairs chief executive and race relations conciliator John Clarke was also dropped from Thursday's speaking list.
