Winder, with 25 years' experience in financial markets, joined Westpac in 2010 and has been acting chief financial officer for the institutional bank since June 2012.
"Terry's broad experience brings a strong commercial focus to the role, along with a deep understanding of the institutional banking business and an ability to navigate a changing regulatory environment," Westpac group executive Rob Whitfield said.
Between 1998 and 2009 Winder held senior treasury positions at Merrill Lynch in the investment bank's Tokyo, Sydney and London offices. His roles included international treasurer covering EMEA and Pacific Rim regions and chief administrative officer in Australia.
