The $3 billion Energy Industries Superannuation Scheme (EISS) will sell its buildings worth $200 million and reinvest the funds into listed and unlisted property.
The board approved the investment strategy following a review which found the property portfolio was too small for the fund to be sufficiently diversified.
Property developer CB Richard Ellis has been hired to sell the four properties.
"We believe we can gain more consistent returns for our members through the property trust sector without having to commit the financial resources and personnel to managing a direct property portfolio," EISS chief executive Jim Thomas said.
The properties will be sold separately or together through an expression of interest campaign which closes on 11 October, 2007.
"The sale campaign is expected to generate widespread interest as a result of the quality and diversity of assets," CB Richard Ellis director Robert Sewell said.
The buildings are two offices and two industrial properties in NSW.
