Mercers Australian and New Zealand chief executive Peter Promnitz has been made region head for the group's Asia Pacific operations.
Promnitz, who is also a director of the group's trustee company and chairman of its investment committee, continues to be based in Sydney but will now drive Mercer's expansion into the Asia region.
"Growth in this region is currently outpacing Mercer's global growth rate, and we expect this to continue as we bring the best of the global model to the Asian region," Promnitz said.
Promnitz has some existing experience of working in Asia. He was Mercer's Asia Pacific retirement leader in conjunction with his chief executive role.
"Issues such as talent shortage, managing an ageing population and improving financial literacy are issues common to businesses in Australia, New Zealand and Asia," he said.
Promnitz, who joined Mercer in 2000 and has been country head since 2004, will be replaced by Tim Jenkins, currently head of Mercer New Zealand.
Jenkins replacement in New Zealand will be 20-year Mercer veteran, Bernie O'Brien.
