Māori Television CEO Keith Ikin has resigned from his role in the sender.
Māori TV Board welcomed Ikin and thanked him for his contribution to the business over the past year.
"Keith took over the intestines during a period of significant change and led to the development of a new and ambitious strategy for linking innovative Māori content with the audience in a digital age," said chairman Jamie Tuuta.
Deputy CEO Shane Taurima will be in the role of acting CEO until a replacement is announced.
Māori TV said it had already begun the recruitment process to find a replacement.
In his statement, Ikin spoke of the privilege of working on Māori TV.
"I want to thank the team, who works extremely hard every day to create and send Māori content and the board for the ability to support them to implement changes on Māori Television," he said. "I also want to acknowledge those who fought for Māori Television and what it stands for."
Ikin will leave Māori TV at the end of the year.
This news comes on the back of last week's announcement that Māori TV would cancel current business programs Te Kāea, Kawekōrero, Native Affairs and Rereātea.
Earlier this year, staff members also attended a strike due to a pay gap.
