Sources at the station believe Mr Maxwell's appointment was moved forward to today to avoid taking the gloss off the station's 10th anniversary celebrations tomorrow.

A senior staff member said some staff were anxious and disappointed while others were "fatigued and resigned to the inevitable".
"There's been a feeling that it was all inevitable, if anything, everybody's feeling exhausted by it all."
The person said there were concerns a petition opposing Mr Maxwell's appointment that circulated last year would reveal who signed it, although it's understood former chief executive Jim Mather blacked out the names in it.
"There are quite a few people who are clearly not happy about it so there could be a few resignations," the person said.
Another source said there was an element of fear that Mr Maxwell could rein in the station's editorial department, particularly after its Native Affairs programme highlighted financial discrepancies at the Kohanga Reo National Trust.
Mr Maxwell's selection and appointment has been wrought with controversy from the outset, after revelations Mrs Te Heuheu is a close personal friend.
Mrs Te Heuheu could not be reached for comment last night.
It also emerged that Maori TV did not take up an offer from TVNZ chief executive Kevin Kenrick to discuss the reasons for Mr Maxwell leaving his role as general manager of TVNZ's Maori and Pacific unit last year.
In September, prominent board member Ian Taylor resigned over the selection process.
Willie Jackson, chairman of Te Putahi Paoho, the Maori Television electoral college which has four members on the seven-strong MTS board, confirmed his board was not invited to be part of the final selection process for candidates.
"Although my board is very angry with the Maori TV board in terms of their consultation process there is nothing but respect for Mr Maxwell if he is appointed to the position."
