New Zealand First leader Winston Peters said that he was "pretty confident" that those talks with the main parties would conclude on Thursday evening, but said the NZ First board would not meet to discuss its options until the weekend at the earliest.
Winston Peters told Newstalkzb's political editor Barry Soper he still expects the talks to be wrapped up tomorrow but there'll be no immediate announcement.
It is the third time Peters, best known as an anti-immigration campaigner, has found himself in the role of kingmaker under New Zealand's proportional voting system.
However, BusinessDesk's search for the identities of other NZ First board members hit a few roadblocks.
Both sides have the potential to form a coalition government with the NZ First Party.
"They are not politicians but New Zealanders who believe in the party and wish to make a contribution to the decision-making process".
Winston Peters needs no introduction.

However, his decision could depend on whether the team proves to be a genuine Premier League title contender this season. The Gunners are set to be without Shkodran Mustafi for the game as the defender's thigh injury continues to be assessed.
Unlike the National and Labour parties, NZ First's website gives no details on the membership of its non-parliamentary governance structures although the Electoral Commission carries the party's constitution, which opens with a commitment to "open and accountable government" and "consensus".
Which makes it odd that the party's board of directors is so secretive.
Catchpole said "some of the board members have requested for their names not to be disclosed and so it's either all or nothing so you won't be getting that list" and questioned why the board membership was of public interest.
"You don't want to be going to a vote in these matters".
Peters has previously served in both National and Labour governments. He's been the leader since forming the party in 1993.
"I can honestly tell you I wouldn't take a guess of what anyone is now thinking", Peters said at Parliament, referring to his party's caucus and board members.
"It depends upon the logistical availability of the board, which could be Saturday, Sunday or Monday", he told reporters in Wellington.
