FirstChoice is also offering advisers the ability to agree with investors to dial down trails on FirstChoice Investments, Super and Pension investment options, CFS chief executive Brian Bissaker said.
"It's important to offer flexible pricing arrangements that are in line with changes to industry practice to enable advisers to determine the most suitable strategies for their clients," he said.
Some of the new investment options will also include no ongoing management fees or transaction costs.
The investment options available on the platform include FirstChoice Multi-Index Series - Balanced and Conservative and FirstRate Term Deposits.
The FirstRate Term Deposits, with no ongoing management fees or transaction costs, will be available to investors on 13 July 2009.
The Multi-Index Series options combine fundamental and traditional index capabilities and provide diversification of asset classes in one investment option.
The latest enhancements, effective from 1 June 2009, reflected ongoing consultation with advisers about what they needed to help manage their clients' investment objectives and in turn navigate through these challenging economic times, Bissaker said.
"Colonial First State is committed to ensuring the range of investment options available on the FirstChoice menu can help meet investors' needs by giving them access to relevant specialist options from leading Australian and global investment managers," he said.
"We're excited to be able to further expand our investment choices for investors, particularly those seeking a defensive allocation as part of their portfolio mix."
