MediaWorks chief executive Sussan Turner has resigned, saying it is time for her to move on.
Turner had been chief executive for four years, but said in a memo to staff today that after "30 years of nonstop action" the time had come for her to contemplate what was next.
"As we went into receivership, I made a promise to get us safely through that and out the other side," Turner said.
The board was working to find a new leader for the company and had been "understanding" of her decision to move on, she said.
"My family is looking forward to reacquainting themselves with their mother/wife (I think)."
MediaWorks owns TV3 and FOUR and numerous radio stations, including The Edge and More FM.
