If you’re only moving to Australia temporarily
You can keep you KiwiSaver account open. Your money will remain invested while you’re away.
If you transfer your savings to an Australian Super scheme, you won’t be able to transfer it back to the OneAnswer KiwiSaver scheme.
If you move to a different country
Once you’ve transferred your KiwiSaver savings to an Australian Super Scheme (or vice versa), those funds can’t be transferred to a third country.
