"We need a better level of understanding," he said.
Mr Wilson said innuendo could become perception and perception could poison people's minds.
He had personally encountered "volumes of misinformation" - a lot of it from Maori who had not taken the time to attend hui dealing with the Treaty settlements.
He said Maori who were opposed to the settlements held fast to the beliefs that it was all the Pakeha's fault and no amount of money or saying sorry was going to fix that.
Te Kohinga's goal was for people to hear the truth and to have their questions answered by experts who had the knowledge.
The forum will run from 7-9.30pm.
Mr Wilson said the forum was not intended as a chance for the audience to make speeches, but to allow them to ask honest questions.
It will be chaired by Tauranga solicitor Graeme Elvin.
