The person who recorded the row between outgoing National MP Nick Smith and a staffer no longer works at Parliament.
After 30 years, Smith abruptly threw in the towel on his political career on Monday, citing the loss of the Nelson seat and a Parliamentary Service inquiry into a "verbal altercation" in his Wellington office last July.
He was also under the impression details of that inquiry had been leaked and would hit the headlines on Tuesday, but no such story has appeared and it's not clear why he was told one would be coming.
National leader Judith Collins has previously said a staff member of another MP recorded the spat and then made a complaint to the Parliamentary Service.
She told reporter Sarah Robson Nick Smith is in good spirits.
