Edwards has been with DDB for 19 years, 16 of which was spent at their office in Korea. He is returning to his native New Zealand with his family on 21 June.
According to Ted Kim, who was appointed as chief executive of the Korean office in November last year, Edward's role will be divided between Kevin Koh, chief operating officer, and Leslie Oh, business and talent manager, at DDB Korea.
A spokesperson from the agency has indicated that DDB hopes to continue working with Edwards after his return to New Zealand.
