Tauranga Moana iwi representative Antoine Coffin said there had been periods of positive relations between Maori and British but that was often eclipsed by the wars. "We still reflect on that conflict but not so much the time of peace and prosperity," he said.
He asked the audience to ponder a future borne out of more positive memories.
