The move follows the launch in August last year of full-service research offices in Jakarta and Kuala Lumpur.
Kadence has also revealed plans to further expand its presence within the Chinese market with the launch of a Shanghai office before the end of the year.
Kadence said that it has increased its reach in Asia-Pacific within the last year in response to the growing demand for business research into the progressive economies of this high-growth region.
It said that the Hong Kong office was prompted by the continuing success of Kadence's other Asian operations and the need to offer a permanent local site capable of efficiently coordinating and managing the growing volume of research studies into Chinese business markets by regional and international clients.
Simon Everard, Kadence group chairman, said: "Kadence's success as a global insight agency has always been based on having a strong 'on the ground' presence in the markets it researches.
"As well as offering benefits to clients that are exclusively researching a Chinese audience, our Hong Kong office will also offer significant advantages to international clients requesting regional insight within the context of a global campaign."
Matthew Coulter, research director of Kadence China, said: "Kadence already works with many clients that operate within the Chinese market, or are looking to do so. We are delighted to align our offering with their needs by establishing a formal presence within the country."
