Cooper declined to talk to the Herald about his role in Coliseum but Martin said the company had a clear game-plan to package up English Premier League soccer to meet consumer demand for slick sports content.
Coliseum was looking at other soccer competitions for online coverage and would ultimately target other sports, he said.
The company had already worked with New Zealand Cricket and the Rugby Union on other marketing roles.
Cooper was approached because he would open doors for the company, Martin said.
Martin and his wife, Kate - who both have a background in advertising and marketing - co-own MMCT with Simon Chesterman and Kate's father, Kenneth Taylor, who introduced them to Cooper.
Cooper is well liked in Auckland business circles and known as the developer of Britomart.
He and his family have homes in Newport Beach, California, and Takapuna. It is understood he also spends time at Cooper & Co's Mountain Landing Development in the Bay of Islands.
"Peter has a lot of interests beyond property - including some very interesting green projects," Martin said.
"But Coliseum is a left-field investment for him, as this sort of investment is for anyone," he added.
Cooper is a former executive director of Lion Nathan and chief executive of LD Nathan. He practised law for 11 years andwas a partner at Russell McVeagh in Auckland, where he specialised in commercial and property law.
