"I can confirm no changes really that are taking place because I haven't been fully in the loop -- and I must be in the loop before changes take place."
Asked for assurances about the future of the station's news and current affairs department, Dr Sharples said: "I can assure you they will keep going."
He was also unsure whether there had been any political interference from both the National and Maori parties for the station's Native Affairs show allegedly taking a sometimes hard line on their politicians.
"What I have asked for is that due process take place and that they consult their stakeholders which is the Minister, the other Minister (of broadcasting, Bill English) and Te Putahi Paoho."
Dr Sharples said "all Maori support" Maori Television and it was hard fought for. He said he was awaiting a report outlining the changes in full.
Maori Television last night also denied Mr Harawira's claims.
The Mana leader said other questions including whether Native Affairs would be turned into a "magazine-style show" and if the head of news and current affairs, Julian Wilcox, would see his role disestablished demanded "immediate answers".
Mr Harawira blamed political bias and interference from the National and Maori parties in downgrading Native Affairs and dumping Te Kaea.
He asked why news and current affairs staff were not consulted in the broadcaster's "structural realignment". Dr Sharples should stop the process dead in its tracks, he said.
Last week, CEO Paora Maxwell told staff the strategic alignment plan had been accepted by the MTS board and "change was imminent".
An MTS spokeswoman acknowledged last night that a review was under way and said an announcement to staff would likely be made in the next few days.
