This week, the mother-of-two told a women's magazine that her husband had resorted to taking the cleaning contract because "he has no choice, he has to provide for his family ... We have bills to pay like everyone else. We don't own a house, we're paying rent like many other people and getting by is a struggle".
Cairns and his 34-year-old wife, who works fulltime in a project management role, live in exclusive Herne Bay, Auckland's most expensive suburb, where neighbours include Karl Urban, David Cunliffe and best friend Nash.
The father-of-four has steadfastly denied all cheating claims and patiently awaits resolution to the official investigation.
On Friday night, at a Britomart hotspot where newsreader Wendy Petrie was holding court, The Diary observed Cairns at the bar.
He bowed out graciously, apparently after hearing some taunts and mockery from other patrons.
His best friend says he knows he'll just have to cop it until his name is cleared.
"I'm sure he feels like an outcast, and people don't make things easy for him," said Nash.
"But does he go someplace where no one knows him? Until he proves his innocence he just has to soak it up and work hard."
Breakfast show gag order
Mark Staufer told The Diary yesterday he is gagged from speaking out about why his breakfast radio show was dumped from The Sound after only five weeks on air for fear of breaching an exit agreement.
The Kennedy & Staufer Breakfast Show was abruptly killed off last Friday, with parent company MediaWorks quietly issuing a memorial notice on Sunday morning.
A spokeswoman candidly told The Diary it was a good leadership decision to make.
"We did lots of tracking but we felt the show wasn't a right fit for the Sound brand. We made the decision now rather than later. We are relocating both Mark Staufer and Mark Kennedy back overseas. "
Staufer, who drew headlines this month for a profanity-littered on-air rant, took to Twitter to express his sorrow. "Thanks for all your support, my friends. It's been my Septimana horribilis, truly."
A permanent replacement for the pair is yet to be found, but a radio insider says dumping the show after only five weeks at the helm is very unusual and indicates a no-nonsense "fail fast" approach by executives.
