"We're all a big family when we go on tour and you have little incidents there but we all dealt with that," said Kidwell.
"We had standards, we had protocols. Everyone else followed them. I trusted those guys, those senior guys in the team, and we've moved on from that decision and we're moving forward."
Kidwell also refused to be drawn on an interview Bromwich did last week with Melbourne's Herald Sun, suggesting the Storm NRL front-rower kicked-off a seven hour drinking session after the Kiwis 30-12 defeat at GIO Stadium and consumed more alcohol at the team hotel before going out on the town at around 1am.
The official line from the NZRL was that the players had returned late to the team hotel for a dry dinner before a small group of players and team staff went out for a quiet drink.
"We've reported what happened from us," said Kidwell. "We had a dry dinner. No one in that dinner had any alcohol."
Kidwell then declined to confirm reports that Bromwich was on pain medication after the game and under explicit instructions from the Kiwis team doctor to stay off the drink.
When pressed on why he could not provide an answer, the NZRL's general manager of marketing and communications, Philippa Ivory, interjected saying the matter could not be discussed due to doctor-patient confidentiality.
"We've made it really clear what we believe happen and we can't comment on what other people say. It's not reasonable," said Ivory.
Kidwell also refused to discuss claims that Bromwich has been left unhappy, after he reportedly volunteered to stand down himself down from World Cup selection, with Kidwell insisting he make the public announcement that both players would be banned from playing in the end of season tournament.
"I'm not going to get into the details," he said. "I've had private conversations with both of those guys. They know and I know what decision we came up with. They knew that that was the decision that I made and they accepted it and we move on."
Kidwell and Blair, together with the Kiwis senior leadership group, are now reassessing their team protocols and considering whether to go alcohol-free throughout the World Cup.
New Zealand and Australia will co-host the end of season tournament with seven matches being played between Auckland, Hamilton, Wellington and Christchurch.
Blair believes a no-booze policy would be a small sacrifice for the players to make over the duration of their five-week campaign.
"If you look at the bigger picture, no (it isn't a great sacrifice)," said Blair.
"When you get selected in this team we're here for a purpose and we make sure that we're driving the same purpose.
"So if we have to make some sacrifices, we'll do what we have to do to make sure we're there in the end to achieve the main goal that we're there for."
