Following his suspension from the kura in 2007, Mr Mutu went on to become the chief executive of a national organisation that supports the development of kura kaupapa.
However, on October 20, just 10 days after his hearing, Mr Mutu informed the tribunal that he had left his job at Te Runanga Nui o nga Kura Kaupapa Maori o Aotearoa.
Mr Mutu had worked with Te Mana Kuratahi in an administrative role on a voluntary basis, Ms Milne-Ihimaera said.
She said that she had not known the full extent of the charges faced by Mr Mutu, nor had she discussed the appropriateness of his appointment with any of the national committee.
When asked if Mr Mutu would continue to be involved with Te Mana Kuratahi in the future, Ms Milne-Ihimaera said that decision would be up to the national committee.
"It's not an appointment, they're just voluntary positions that he volunteered for,'' she said.
"It's a voluntary role but my opinion is we'd continue to value Hone's participation in kapa haka.''
The Northern Advocate was unable to contact Mr Mutu yesterday.
Mr Mutu's wife, Deborah Mutu, was also deregistered from the Teachers Council for her role in not properly investigating the allegations about her husband's misconduct.
She was principal of the Kaikohe kura, and Mr Mutu a teacher, when the incidents of serious misconduct occurred between 2004-2007.
