Legislation will be introduced to Parliament in two weeks' time to allow New Zealanders returning home from Australia to bring their retirement savings with them.
It could lead to billions of dollars being repatriated to New Zealand.
Australia's tax office estimates that it holds $13 billion in lost accounts in the Australian superannuation system.
Finance Minister Bill English thinks much of that money belongs to New Zealanders who have already returned.
He says the new law will enable them to bring the money back here, but they will have to invest in KiwiSaver accounts.
Provided the same law changes are made in Australia, Mr English says, the new arrangement should take effect from the second half of next year.
