Prime Minister John Key is "absolutely confident" he will have confidence and supply deals with Act and United Future settled this week.
But he is only "optimistic" that he can pull off an agreement with the Maori Party.
The Act and United Future deals would give Mr Key the numbers to govern.
The expectation is, however, that Mr Key will delay going to the Governor-General until he has an answer one way or another from the Maori Party.
National negotiated support deals with all three parties after the 2008 election but the numbers are tighter this time.
Mr Key yesterday reiterated what the Herald reported on Monday - that support for partial state asset sales would be part of Act and United Future's agreements but would not need to be part of any confidence and supply deal with the Maori Party.
Numbers are needed from Act and United Future because in order for the assets to be partially floated, they have to be removed from the State Owned Enterprises Act.
Mr Key made his comments yesterday about the talks ahead of his party's first caucus meeting since the election.
The party increased its numbers by two but because of retirements and changes in list rankings, it welcomed eight new faces: Maggie Barry, North shore MP; Ian McKelvie, Rangitikei; Mark Mitchell, Rodney; Mike Sabin, Northland; Simon O'Connor, Tamaki; and Auckland-based list MPs Alfred Ngaro and Jian Yang.
