ASB says a change in the way the regulator views personalised financial advice has opened the door for it to provide more KiwiSaver advice.
The bank, which is the country's second largest KiwiSaver provider, has launched a new in-house tool called KiwiSaver Explorer to help people decide whether to join KiwiSaver and which fund they should be in.
The move comes after the Financial Markets Authority revamped its guidance on financial advice after its research found just three in 1000 Kiwis were getting personalised advice for KiwiSaver.
Jonathan Beale, ASB's general manager of wealth, said introducing the tool would not have been possible without the new guidance.
"We were like a lot of other providers. We were confused by the previous guidance."
