New Zealand First have released a statement saying they will be announcing their decision on the result of negotiations on the next government tomorrow afternoon.
Mr Peters avoided media after talks with his caucus this afternoon, instead choosing to release the information through a statement which read:
"New Zealand First have said they will be in a position tomorrow afternoon to make an announcement on the result of negotiations following the 2017 General Election.
"New Zealand First Leader Rt Hon Winston Peters said he had spoken to the leaders of the National Party and the Labour Party today and, amongst other matters, advised them of that."
The announcement comes after Mr Peters had one-on-one talks with Bill English and Jacinda Ardern last night leading to speculation a decision on which way his party might go was near.
It is unclear at this stage exactly what time the announcement will be made in the afternoon, but 1 NEWS NOW will bring you any updates as soon as they happen.
