Winston Peters says NZ First board meeting will be on Monday
NZ First will hold an all day joint-caucus and board meeting on Monday to decide which party to give their support to.
Leader Winston Peters, wearing a tie emblazoned with the acronym "TGIF", told media on Friday that the board members will be flying in to Wellington from all over the country on Sunday evening and Monday morning.
"TGIF" stands for "Thank God It's Friday."
His party could put either National or Labour in power, although Labour would also need the support of the Green Party.
While formal negotiations with the two parties had wrapped up Peters, said he was still in contact with them to nail down fiscal and policy issues.
"We have to get the policy thing cleared up first. And also an understanding of the fiscals. We've been through their budgets and our own and we've got to make sure that we do it on the figures we've agreed upon," Peters said.
There would be "constant communications" between the parties.
NZ First are holding an all day caucus meeting on Friday.
"We worked overnight and early in the morning with the objective of getting as much completed in terms of a summation both from the caucus' and the board's point of view ... making sure we have a very clear idea of what we need to enquire from the other parties to make sure there is doubts," Peters said.
"The board members will be flying in on Sunday and early Monday-morning for an all-day board meeting on Monday," Peters said.
He said the board members had hotels booked in case the meeting went into the night.
However, this did not mean that a final decision would necessarily be made public on Monday.
"It's extraordinarily difficult to meet timelines, particularly on this matter that if you are jamming a timeline against a public statement of a date, and you compromise the quality of your decision, that would not be a very good idea, but we know time is of the essence."
He said his comments about the decision being ready "by the end of next week" had been "seriously misconstrued" - he meant that the decision would likely be far sooner than that.
However he was keen to get the decision announced publicly as soon as possible.
"The quicker we make it the less the chances are of it being leaked," Peters said.
Peters told media he has a "serious comprehensive dossier" from both parties to take to his caucus and board, promising that a new Government would be decided by next Friday.
He already missed his first self-imposed deadline of Thursday, or "Writ Day".
"I'm very very pleased we've got it finished. We've got a serious comprehensive dossier from both sides and there's some fiscals to be shared to make sure we do agree but the substantive part for discussion of caucus tomorrow has been done," he said following the final negotiation meeting on Thursday.
JAMES SHAW: 'READY TO GO'
Green Party leader James Shaw said he had a standing conference call booked with party delegates for every day, so they would be ready to approve the decision as soon as it was ready.
"We're pretty much ready to go," Shaw said.
He said negotiations with Labour have mostly finished but there were still some small things to finalise.
"There's still bits and pieces that we need to tidy up," Shaw said.
"We're nearing the end stages."
He was still keen on a full coalition arrangement with all three parties inside Cabinet.
Labour leader Jacinda Ardern did not answer questions about what steps her party would go through on Friday morning, other than to say "we have our own process."
"Overall this has been a good process that has been followed," Ardern said.
On his way into work on Friday morning new NZ First MP Shane Jones said the amount of time taken to make the decision was reasonable.
"I think Winston has outlined the election result was announced relatively recently, we've made good progress on our policy matters," Jones said.
NZ First's Mark Patterson said there would be a lot to get through in the meeting.
"The talks have been conducted with the highest integrity, at my level we haven't had any visibility of what's happening," Patterson said.
"I expect there will be a lot to get through."
Finance Minister Steven Joyce would not comment on the content of the meetings or the timeline on his way into work on Friday morning.
