"Sorry. I can't do much about it. He's a Government minister,'' the official reportedly said.
Today's R&M column has the headline: "Kiwi PM really is off Key: our 'gossip' is pure gospel.''
"Jeeves'' has never let me down,'' Growden wrote.
"All I can say is that my sources are impeccable.''
Government ministers Maurice Williamson, Wayne Mapp and Jonathan Coleman were the three in the box but all categorically deny having behaved badly.
Prime Minister John Key said yesterday he had also spoken to others who were in the box and had been told the ministers' behaviour was appropriate.
"It's worth putting a bit of perspective on this, this is an unnamed gossip columnist reporting a theoretical unnamed minister in a gossip column.''
Growden's column was dismissed by Mr Key and his ministers as essentially "made up''.
Others who were in the box have backed up the ministers' version of events, although Mr Williamson was described as being "boisterous'' during the game.
