Three executive managers have been affected by changes to UniSuper's management team following a review.

The fund's executive manager of member and employer services Val Abbott and executive manager of technology Sean Churchward have left the fund.

Executive manager of marketing and business development Paul Murphy will be leaving the fund in August 2010.

The changes were a result of a review of the business, according to a statement from the fund.

Under the restructure, teams focused on members and employers will be merged into a single business unit called UniSuper Advice & Services. The business will be led by Chris Davies, who is currently the executive manager of UniSuper Advice.

Administration, operation and technical teams have also merged into a single business called Business & Technology Operations, led by Tony Loprieato. Loprieato is currently UniSuper's executive manager of project delivery and change.

The investment team led by chief investment officer John Pearce has been unaffected by the changes, the super fund said.

"UniSuper wishes to place on record its sincere appreciation for the significant contributions that Val, Sean and Paul have all made to UniSuper during their long tenure with the organisation," the statement said.

"The ultimate aim of this restructure is to achieve better outcomes for our members as we align our resources to best meet our business requirements into the future."
