A national interest test will be brought in through phase two of its Overseas Investment Act reforms.

Associate Finance Minister David Parker says the Crown should have a say on whether things like airports, lines companies, or water providers ... should only be sold to Kiwi companies.

He says at the moment there's no way to turn down foreign purchases - as long as the buyer's not corrupt and can manage the investment.
