UBS Australasian chief Colin Woods said an opportunity to "go and build" has led him to leave the top job to drive the bank's business growth in South East Asia.
Woods is to head UBS Global Asset Management's retail third party distribution arm in Asia from February 2007.
Based in Singapore, Woods will work with fund managers and financial service providers in Singapore, Hong Kong, Taiwan, Thailand, Indonesia and Australia.
The Australian head of the Swiss investment bank says he has had "a great job" for the last three and a half years but welcomes the opportunity to grow the business on the strength of the Asian economy.
Woods added that the Asian operation will encompass 'the whole gamut in the UBS factory" of asset management. He will continue to coordinate the bank's retail third party efforts across the Asia Pacific region.
Earlier this week AMP announced it enlisted UBS to assist with the start its new Capital China Growth fund. Alliance Bernstein institutional head Paul Bolinowsky will succeed Woods.
Alliance Bernstein chief executive Michael Bargolz said he will assume Bolinowsky's responsibilities until a successor is found.
