The news follows the resignation of Geraldine McDonagh, who was the chief digital officer of the company. She will leave the agency on June 28. Her role will not be replaced.

“It’s now time for me to build on the great experience I have gained at Zenith and look for a new challenge within the media and marketing industry,” McDonagh said.

Prior to joining Zenith, Johnson was group director of digital at MediaCom Australia for three years. He has also worked as performance director and senior search manager for MediaCom, as well as digital insight consultant at Latitude.

Johnson said: “Zenith has a strong digital team and a great offering for clients. With the agency’s focus on ROI and marketing-led growth, we are well placed and I’m excited to lead the team in Sydney to deliver results for our clients.”

Zenith Australia CEO Nickie Scriven said: “Mark came to Zenith earlier this year with a wealth of digital experience. In just six months he has made exceptional inroads into our digital performance structure, people, product and processes.

“With Geraldine’s departure we have an opportunity to recognise this great work and allow Mark to lead the entire digital team in Zenith Sydney and ensure we are well prepared for the future in this constantly evolving media landscape. I’d like to thank Geraldine for all of her hard work and commitment to Zenith. She will be missed by the executive team and the broader agency and we wish her all the best in her future endeavours.”
