Labour's launching a campaign to ensure Kiwibank stays in New Zealand hands.
Leader David Shearer wants the Government to support a private members bill which he says will help keep it locally owned.
The bank is currently owned by New Zealand Post, which is a state-owned enterprise - and Mr Shearer says it's vulnerable to future asset sales.
"We felt that it was important that Kiwibank, which is an icon of New Zealand, is actually put into a situation where it would need three-quarters of Parliament to vote in favour of selling it before it would be able to be sold off, whether in whole or part."
John Key has ruled out selling Kiwibank while he's Prime Minister, and Mr Shearer says he should back that up by supporting Labour's bill.
