Matthew John Mulvey, 43, appeared in the Dunedin District Court, where he had three months added to his sentence after admitting possessing the class-A drug and unlawfully having prescription medication.
In 2016, the defendant was jailed for 10 and a-half years after a high-profile Christchurch trial featuring several Mongrel Mob members.
Mulvey lured the victim to his home, where the man was viciously assaulted by the group over several hours, Stuff reported at the time.
The man was bashed with hammers and knuckle-dusters, punched, kicked and struck with an ashtray inside a sock after being kidnapped.
Stuff reported the victim was bound hand and foot, and threatened with being stabbed in the face, or having his family home "visited".
After more than seven years behind bars, Mulvey arranged for a visit at the Otago Corrections Facility from a female associate on March 3.
While they talked, she removed a package and handed it to the inmate.
The exchange, though, was captured on CCTV and Corrections staff found it when they searched Mulvey.
The contents comprised 4g of methamphetamine and 50 Tramadol tablets (an opioid used to treat severe pain).
Counsel Josh Lucas said the crime had greater consequences than just the three-month addition to Mulvey’s sentence.
He had recently seen the Parole Board, which had declined his release for at least another two years.
"He now knows his parole chances have gone significantly downwards and he’s going to have to work very hard to bring back the trust of the Department of Corrections," Mr Lucas said.
The woman involved in the smuggling, whose name was suppressed, was sentenced to six months’ home detention and 80 hours’ community work last month.
The court heard she was under significant duress in making the delivery and had no idea what was in the package.
