Labour's leader Jacinda Ardern says her talks with New Zealand First and the Greens have been extremely productive.
In a message to Labour supporters, she said she was looking forward to forming a government she would be proud to lead.
Ms Ardern said the talks with both the Greens and New Zealand First had been robust.
"There is a period of a wait now while the different parties consider their different positions.
"But I can certainly tell you as the leader of the Labour Party, I think the process has been robust, it's been exactly the kind of process we need to make sure that we give full consideration to the best government to take New Zealand forward.
"It would be a government that I would be proud to lead."
Monday is the day the New Zealand First board and caucus will meet to decide whether to support National or Labour in government.
Winston Peters has said the timing of any announcement will depend in part on the outcome of that meeting.
