Quek, who will depart this summer, led the agency through a period of sustained growth in China, netting Consultancy of the Year at the 2006 Asia-Pacific PR Awards.
Meanwhile, Hill & Knowlton has continued to bolster its regional leadership, naming Australasia technology director Myrna Van Pelt to oversee industry analyst relations.
"Technology analysts are critical influencers who shape the development and roll-out of products, solutions and services in the technology sector. Their views help drive sales, influence stock valuations, and can build or hurt corporate reputations," said Joshua Reynolds, Hill & Knowlton's global technology practice director, and a former Gartner analyst.
In addition, the agency has promoted Rachel Chan to head its Greater China financial communications, and has appointed Crystal Dong as director of financial communications in Beijing.
