Legislation allowing the partial sale of state-owned assets will be passed by Parliament without any difficulty, Prime Minister John Key says.
The government has a majority of just one vote on the legislation after completing support deals with minor parties.
With the Maori Party is has 64 votes in the 121-member Parliament, but its three MPs oppose asset sales and the agreement allows them to vote against it.
National has 59 seats and Mr Key is relying on ACT's John Banks and United Future leader Peter Dunne to get it through.
"We've got 61 votes on it and that's rock solid," he said on TV One on Monday.
"I don't have any reason to think there's going to be any problems."
Mr Key says he believes passionately that the partial sale of state asset is the right thing to do because he's going to use the money for essential infrastructure development.
