Jail commissioner Joseph Ponte will pay the city back for the gas, mileage and tolls that he racked up during his unsanctioned trips to Maine, a spokesperson says.

City Hall confirmed Monday that the Department of Correction head had agreed to cough up the $1,043.44 that he spent on fuel and $745.56 in E-ZPass charges.

Ponte, who ran Maine’s correction department before landing in New York in 2014, logged more than 18,000 miles of out-of-state travel over the span of 90 days as he made the trips to his home state in a city-owned vehicle.

Thirty-five of those days were said to have fallen during the work week, according to a Department of Investigation report.

Ponte’s gallivanting — which was completely unsanctioned — was later defended by Mayor de Blasio.

“I don’t begrudge someone if they need downtime, so long as they get the job done,” the mayor said. “And he worked very hard, and has continued to work hard for the people of New York City.”

Hizzoner also rushed to his defense on Monday, as well.

“He was ill advised by colleagues, I believe, and made a mistake and he’s been very straightforward about it,” de Blasio explained on NY1. “He never intended to do anything wrong. And I think he’s doing the right thing by making the city whole.”

When asked about the fact that he was out of state for so long, the mayor said: “Judge by his results — look what he has achieved….It’s a tough job. He’s done it well.”

It is unclear if Ponte will have a deadline on paying the money back.
