New KiwiSaver rules unveiled in today's Budget will mean all fund providers who look after KiwiSaver money will have to make more information available to members.
Around 15,000 New Zealand have joined each month over the past year, taking total membership to just under two million people. KiwiSaver funds have grown from $9 billion to $12 billion in that time.
A plan to start "auto-enrolling" people in KiwiSaver from 2014 has been deferred til an undisclosed future date.
One criticism of the KiwiSaver scheme has been the lack of any standardised, regular disclosure of fund performance and fees, which makes it difficult to compare rival schemes.
Changes announced today will require fund managers to report performance and returns, fees and costs, assets and portfolio holdings, liquidty and liabilities, and key personnel, along with any conflicts of interest, in a standardised form on their websites.
