Mr Rankin informed Mr Joyce of what he believed was a breach of the Education Act, on May 11. He said for an educational institution to call itself a university when it was not recognised as such was a breach of the Education Act.
"I am not so concerned about this technicality. What really bothers me is that those Maori students graduating from Awanuiarangi are being told they are graduating from a university and this is a lie.
"Awanuiarangi is selling a product claiming it has the stamp of a university on it when it doesn't," Mr Rankin said.
Speaking to The Daily Post from Australia, Te Whare Wananga o Awanuiarangi chief executive Professor Graham Smith said the term was used as a describing word and not a noun.
He said that legally they could not name themselves a university.
"It's not in the name itself," Dr Smith said. "You're not allowed to use it as a noun."
He said Te Whare Wananga o Awanuiarangi was a wananga and that was what they wanted to be.
They did not want to be a university, he said.
