Industry super fund Rei Super has renewed its $650 million mandate with investment consultant Intech for another three years.
Intech, which first signed with Rei Super in 2000, will implement the fund's investment strategy through Intech's multi-manager trusts.
Intech manages more than $28 billion in funds under advice.
In November, the firm was bought by Skandia.
Rei Super chief executive Mal Smith said the Skandia deal would create more opportunities for the industry fund.
"The recent acquisition of Intech by Skandia will add to Intech's strong investment capabilities and provide us with an even wider suite of products in the future," Smith said.
