The executive manager of operations at a $17 billion industry superannuation fund resigned recently, with a replacement yet to be appointed.
Rachel Reynolds has exited CareSuper after just under five years.
Confirming the departure, CareSuper chief executive Julie Lander said the move was recent and the fund has not yet hired a replacement.
Prior to CareSuper, Reynolds worked as head of operations at Guild Superannuation Services.
Commenting on her decision to leave, Reynolds told Financial Standard: "I am taking a short break, spending time with my family before exploring opportunities in the New Year."
Earlier this year, Financial Standard reported that CareSuper was experiencing ongoing technical difficulties after switching administrators from Link Group to Mercer.
