AustralianSuper has appointed Dave Oliver as the new deputy chair after Paul Howes left in July.
Oliver joined the fund's board in July 2007.
"Serving on the board of Australia's largest superannuation fund is a great responsibility because you are the custodian of the retirement savings of millions of Australian workers.
"I look forward to working with Ian Silk, Heather Ridout and the rest of the Australian Super team to continue delivering high returns to members and promoting the benefits of not-for-profit industrial superannuation funds to all Australian workers," Oliver said.
Oliver is the secretary of the Australian Council of Trade Unions and was elected in 2012.
Chair Heather Ridout welcomed the appointed and wished him the best.
Ridout also thanked Howes for his seven years of service.
