The former Demons captain had been linked to a bid by ex-Victorian treasurer Alan Stockdale to take on the club's presidency.
"There's absolutely no ticket that I'm a part of," Neitz told AFL.com.au on Friday.
Neitz said he has spoken to Stockdale, and said he would be a "strong" candidate, but stressed he has not endorsed anyone for the job.
"It's not about me endorsing a ticket," Neitz said.
"It's not about me or any past players joining a ticket."
Neitz said he thought new chief executive Peter Jackson was doing a good job at Melbourne, and called for unity, saying it was the best path forward.
"I think some of the moves that Peter Jackson has made have been good moves," Neitz said.
"Now it's about getting the right people in place, and to do that we obviously need to work with all of our stakeholders.
"I think there's reason for optimism going into next year, but as a club we need to be sure we're united."
AFL.com.au revealed in June that Stockdale was a candidate for the Demons top job.
Since then he's had conversations with key people at the AFL, and is currently considered the leading candidate for the role.
The AFL Commission discussed a financial compensation package for the Demons at a meeting earlier this week.
AFL chief executive Andrew Demetriou said on Friday the AFL was involved in a "nominations committee" looking at the composition of the club's board.
It's understood that package is contingent on the club, and its new board, meeting a number of requirements.
"It's incorrect to say that the AFL is appointing the board. They've got a proper process in place. It'll be a joint project with the AFL and the Melbourne Football Club," Demetriou told radio 3AW.
Demetriou confirmed Stockdale was a candidate, but said there was no firm view on who should take on the job.
"Alan's been pretty co-operative and proactive," he said.
Stockdale is currently leading the Liberal party's federal election campaign, in his role as party president.
