Clemenger Group's Hylton Mackley AM dies

Chairman Emeritus of Clemenger Group New Zealand and former Colenso founder, Hylton Mackley AM, has passed away.

In 1969, Hylton became one of four founders of Colenso, New Zealand's largest marketing communications company at the time.

Clemenger Group purchased a stake in the agency in 1973 before it merged into the Group in 1987.

Hylton Mackley was then appointed finance director of Clemenger Group until 2011, which he then became a non-executive director of the company and, more recently, chairman emeritus of Clemenger Group New Zealand.

Outside of Clemenger Group, Hylton also served as treasurer of the Victorian Artists Society (FVAS).

He supported the restoration of the Society's Heritage Victoria and National Trust listed building, which led to an award and exhibition hosted in his name.

He was a director of the Barnett Foundation, a not-for-profit organisation involved in the affordable housing sector. 

Hylton received an Order of Australia (AM) in 2018 for his contribution to the Advertising Industry and the Arts.

“Hylton’s contributions shaped Clemenger Group and the industry in both New Zealand and Australia for more than 50 years," said former chairman of Clemenger Group, Robert Morgan.

“His mischievous and entrepreneurial spirit has also remained part of Colenso’s DNA.

"The agency’s annual celebration of Founders Day recalls the story when Hylton and his co-founders would leave the lights on at the end of the day, making the other agencies think they were working through the night. For those who knew Hylton, this story would come as no surprise.

“On behalf of those who worked with or were mentored by him, I extend our heartfelt condolences to Hylton's family, friends and all those who had the privilege of knowing him. Our thoughts are with them during this difficult time.”
