Asked if he wanted to say anything else about the meeting he said he didn't. He was expecting "the same thing" from the meeting with Ardern and her team later today.
Asked if he received a good reception from National's team, Peters said, "take a wild guess", before the lift doors shut.
Previously, National's team went into a ministerial meeting room on the second floor of the Beehive, including Bill English, Gerry Brownlee, Steven Joyce, Todd McClay, chief of staff Wayne Eagleson and adviser Cameron Burrows.
"We have got full faith in whatever decision he makes that Pike River is going to be a top priority."
Anna Osborne said she had no faith that National would take action on Pike without being pushed to do so.
"[Peters] is certainly a man of principle, and he has stuck by his word. And it was one of his bottom lines. And it still is. To have that reaffirmed today has just been amazing."
Shortly before the meeting, Peters told media that re-entry was a serious matter.
"Twenty-nine people lost their lives. They have been denied justice. And it is just contaminated with a whole lot of appalling political behaviour. And so we intend to sort it out."
Asked if his message to National and Labour negotiating teams would be re-entry was a crucial issue he would not move on, Peters said he had said as much "from the very beginning".
Monk said all he wanted to say before meeting Peters was that the New Zealand First leader was a "man of his word".
"We are going to support him the whole way...he has already made his decision on what he is going to do for us...we have got full faith in Winston Peters and what he is going to do."

Peters and his team will meet Labour leader Jacinda Ardern, deputy Kelvin Davis and other senior party figures this afternoon.
Ardern met with the families of Pike River victims yesterday.
During the campaign Ardern met with family members at the Pike River memorial on the West Coast to re-state her commitment to re-enter the mine in which 29 miners died following explosions in 2010.
The National Government has refused to attempt a manned re-entry because its expert analysis said it would be too risky. That was disputed by the families who obtained their own expert analysis.
National has refused to commit to unmanned entry to mine saying it was not a decision for politicians to make and was a matter of health and safety.
However, English has said that unmanned entry to the mine by mine owner Solid Energy was planned by the end of the year.
Some of the Pike River families are in Wellington for a Supreme Court hearing beginning today to challenge a decision by District Court Judge Jane Farish to drop charges against former Pike River boss Peter Whittall.
Instead, Whittall and Pike River Coal paid victims and families $3.41 million which Whittall's lawyer argued would not have occurred if the charges had had to be defended.
That was disputed by the families who obtained their own expert analysis.
