CBC News has learned that the Progressive Conservative party helped Campbellton-Restigouche Centre MLA Greg Davis pay an outstanding rent bill at his constituency office in 2012.
The information has come to light days after a bailiff's notice was placed on the door of Davis's office, stating he owes $6,665 in rent, dating back more than six months.
He has until Saturday to pay the rent owed or 15 items of office furniture will be seized by the bailiff.
The PC party has confirmed the bill would be paid, but would not say by whom.
A similar situation arose at the office two years ago, according to JP Soucy, the executive director of the PC party.
He says on that occasion, the local association came to an arrangement with Davis that was handled "en famille …kept in the family."
Soucy declined to say whether the payment was a loan or a bailout.
The new revelations surrounding Davis's office finances are raising questions about his decision to not seek re-election in September's provincial election.
In a statement on Tuesday, Davis said he won't reoffer due to health reasons, but didn't address the unpaid rent or explain the nature of his health issues.
NDP Leader Dominic Cardy says the PC party should be more transparent about the unpaid bills.
"Why this has happened twice now, why they've had to bail out Mr. Davis and deal with the situation twice," he said.
Members of the Legislative Assembly receive an allowance to pay for local office rent, staff, and office expenses.
Former house Speaker, Roy Boudreau, lost his seat to Davis in the 2010 provincial election. He said "it's hard to justify" the outstanding rent.
"I don't know how it happened or what went on, but something definitely is amiss," said Boudreau.
CBC has been unable to reach Davis for comment.
