Winston Peters says he has a 'totally open mind' and has not yet made a decision

NZ First leader Winston Peters says he has not yet made a decision about which party to choose for a coalition in government.

He also expects his board to have the same "open minded" approach when they meet this weekend to come to a final decision.

"I said I would go into it with a totally open mind and I've asked my board and caucus to take the same approach," he said.

Peters has announced that, due to funeral engagements, it is impossible to get all of his party's board members together for a decision tomorrow.

"We are doing the best we can in the way we can best organise it ... this country is the same size as Japan. The same size as the UK. We are not a little island nation. It takes people time to organise things, particularly since we are coming up to Friday, Saturday and Sunday," Peters told media this afternoon.

Peters said it wasn't an option for those board members to dial or Skype into the meeting.

"We wouldn't want to do it by Skype. You wouldn't want to have a serious discussion like this, over hours on the technology of Skype. Too much can go wrong."

The "Kingmaker" is wrapping up negotiation meetings with Labour and National today and he will now present both proposals to the party's board.

He said the board meeting can happen any time over the weekend or maybe even on Monday, so no doubt the country will remain in suspense.

He added that he does not yet know who to support.

"I can honestly tell you I wouldn't take a guess what anyone is currently thinking."
