"A person studying overseas won't be eligible for member tax credits, even if they make voluntary contributions," said Bishop.
"There are few situations where members of KiwiSaver who are abroad receive member tax credits. These involve working either as a Government employee serving outside New Zealand, or as a volunteer, or for a token payment for a specified charitable organisation, relieving poverty, hunger or sickness.
"An overseas student who doesn't meet these criteria won't be eligible for member tax credits.
"If you move to a country other than Australia, you can apply to withdraw your KiwiSaver funds and close your account one year after you've permanently emigrated.
"You can withdraw everything except for member tax credits you received, so you can take all your contributions, your employer contributions, any investment income and the $1,000 kick-start.
"If you are moving permanently to Australia, you cannot withdraw your KiwiSaver funds early. Instead, you can choose to either leave your funds in a KiwiSaver scheme account in New Zealand or transfer them, including member tax credits, to an Australian superannuation scheme.
"You won't have to wait a year like you do when moving to another country," said Bishop.
At the time of writing, only a handful of Australian superannuation providers accepted KiwiSaver transfers.
