FuturePlus Financial Services general manager of investments Michael Block has left the financial and investment management services organisation.
A reason for his departure has not been given and FuturPlus did not return calls to InvestorDaily.
FuturePlus is owned by Energy Industries Superannuation Scheme (EISS), and the firm is the main provider of investment management services to the super funds.
The departure of Block provides some difficulties for EISS as FuturePlus' investment analyst Chris Drew, the next most senior investment manager, is currently overseas.
But EISS said the super fund could rely on the services of its asset consultant Mercer.
"Mercer is currently EISS' asset consultant and will be able to accommodate any short term issues emerging as a consequence of Michael's departure," EISS chair John Eisenhuth told InvestorDaily on Friday.
