MediaWorks CEO Michael Anderson has stepped down from his role and will leave the company at the end of the year.
Anderson, an Australian, has been in the role for four years and in that time has driven growth in the radio and television divisions.
Most recently, he oversaw the acquisition of QMS Media Limited's New Zealand out-of-home, digital media and production business.
In a statement released on Wednesday Anderson said: "I have absolutely loved the experience of leading this exceptional company over the past four years and it has been a privilege to do so."
"When I joined MediaWorks back in October 2016, my focus was to bring stability to a company that had been through years of turmoil and to get all arms of the business into a position where they would be sustainable and competitive in their own right."
"Fast forward to now and we have welcomed QMS into our family and alongside our radio business, they have come together into one building that allows collaboration across our brands."
"With MediaWorks well and truly on the path to a sustainable and profitable future, it’s time to look at the next phase of our business journey and it is time for a new leader with a fresh perspective to drive MediaWorks over the next five years and beyond."
Chairman Jack Matthews paid tribute to Anderson saying after four years MediaWorks was in a much better position both strategically and financially.
"Supported by a talented executive team and an engaged staff, Michael has driven all areas of the business and as a result, MediaWorks is very well positioned for the future."
"I and the Board would like to acknowledge and thank Michael for his huge contribution. We will be sorry to see him go but he will leave behind an exciting business ready for the opportunities ahead."
