The keynote speakers will include Professor of History at AUT University Dr Paul Moon, economist and philanthropist Gareth Morgan, lawyer Annette Sykes, lecturer in law at the University of Auckland Valmaine Toki, former MP and Tainui leader Tuku Morgan and lawyer Moana Jackson.
Te Kotahitanga has called the hui.
Dr Moon, a leading commentator on the treaty, maintains there is an erroneous belief that the Treaty of Waitangi is the foundation for New Zealand's system of government.
Moana Jackson, a lawyer specialising in Treaty of Waitangi and constitutional issues, is the chairwoman of the Independent Maori Constitutional Working Group and is a strong advocate of constitutional change and the rights of indigenous peoples.
Mr Morgan, at his first visit to Ratana Pa this week, set out two challenges to the Government.
After studying the treaty for five years, and writing a newly-released book on his work, he said Pakeha nearly "exterminated" Maori and needed to make good on the intent of the Treaty of Waitangi - including compulsory te reo in all primary schools.
Mr Tipene said that in the lead-up to the 175th anniversary of the signing of the Treaty of Waitangi, more light than heat was required with regard to the country's constitutional issues so that all New Zealanders were made aware and could contribute to the debate.
He said that would include a move by Prime Minister John Key to change New Zealand's national flag with a possible referendum being mooted for the 2017 elections.
"This is an opportune time to be discussing and debating the constitutional arrangements of our country as we lead into Waitangi Day," he said.
The hui at Otiria will start with a powhiri at 11am on Friday and the keynote speakers will begin soon after that.
Mr Tipene said the hui would be open to everyone - Pakeha in particular needed to not think they weren't invited.
"They're most welcome to attend, debate and discuss how we need to move forward as a nation."
