Publicis prevailed after a final round that also involved Grey, Ogilvy & Mather and JWT.
A further four agencies – BBDO, Leo Burnett, M&C Saatchi and DDB – took part in the pitch’s first phase.
“They have gone through a very rigourous process,” said Publicis Hong Kong CEO Laurie Kwong. “To beat the other agencies is something we’re very proud of.”
