In total, he took 10 packets, worth approximately $200.
Christchurch District Court Judge Gary MacAskill today discharged him without conviction.
Defence counsel Claire Hyslop had argued that a conviction would have travel consequences for Le Coubet who wanted to study and work in the tourism industry.
She said he had done more than 40 hours of voluntary work with the Salvation Army in a gesture of his remorse.
He'd already paid the penalties of having his visa taken from him, and with it his ability to gain paid employment for the past few months. He had also lost his holiday to Thailand with his $1200 non-refundable flights.
Despite the thefts, Le Coubet had "nothing but pleasant experiences" with the New Zealand public during his stay, Hyslop said.
Diversion had been twice declined by police - decisions queried by Judge MacAskill.
Police prosecutor Sergeant Paul Scott said Le Coubet had taken advantage of his access as a cleaner to steal.
In granting a discharge without conviction, Judge MacAskill noted that the cigarettes would have been disposed of and that Le Coubet was otherwise of good character.
The judge also noted that Le Coubet had lost his holiday and flights, as well his work visa and had been relying on his savings and the generosity of others for the rest of his trip.
Judge MacAskill thought police could have used their discretion in granting diversion, saying that it wasn't the case that the Frenchman was a security risk.
He granted the discharge without conviction, satisfied that the inconvenience of a conviction on his future career in the travel industry would have been out of proportion to the crime.
Le Coubet leaves New Zealand later this month.
