Future Fund Management Agency has appointed Treasury Group managing director Mark Burgess as general manager.
Burgess succeeds Paul Costello, who left the fund at the end of 2010 and now is the chair of the government's Stronger Super Peak Consultative Group.
Burgess will continue in his role with Treasury Group for the next three months, while the company conducts an international search for a replacement.
"The board and I would like to congratulate Mark on his appointment to this important position," Treasury Group chairman Mike Fitzpatrick said.
"While we are of course sorry to see him go, the board firmly believes that Mark will be very well suited to this position and his appointment is a testament to his talent and achievements," he said.
"During his time as MD, Mark added three new fund managers to the TRG portfolio and oversaw the merger of IML and Cannae Capital."
"Mark successfully guided TRG through the recent global financial crisis and made a number of crucial personnel changes. He leaves the company in excellent shape with no debt and a very strong management team, who will continue to implement our current strategy," Fitzpatrick said.
Former Treasury Group managing director David Cooper will work in an interim executive capacity alongside Mark during the search.
