State Super chief investment officer Martin Drew left the $31-billion super fund last week.
"We are looking for a new CIO," a State Super spokesperson told Investor Weekly.
Drew joined State Super in 2006, when he transferred from Superannuation Trust of Australia.
He managed the fund's investment advisory team, which monitored all aspects of the investment management process and the performance of the pooled fund.
This included liaison with investment service providers, such as asset consultants, investment managers and custodians.
The fund also appointed a new trustee board member.
Origin Energy chief financial officer Karen Moses has joined the fund as an employer representative.
