Accenture Song ANZ has split the remits of the customer “promise and delivery” firm under two new leads to replace former regional boss Mark Green, who has relocated to New York to be Droga5’s global CEO. Bronwyn van der Merwe steps up from her current role in the high-demand customer service unit to run Accenture Song’s marketing, commerce, design, digital products and service business while veteran Monkeys exec, Matt Michael, becomes CEO of Droga5, officially rebranded from The Monkeys on 1 December. He also has responsibility for Accenture Song’s foray into media planning and buying.
