The 40-year-old will be released from Otago Corrections Facility on parole for the third time after being jailed for five years in 2016 for organising a violent armed robbery, in which a man was shot in the leg.
Tamati's first release ended when he absconded from a rehabilitation programme in June 2018.
He was recalled to prison to continue serving his sentence and was granted parole again in February.
That, too, ended in relapse when Tamati was drug-tested and found to have consumed methamphetamine.
He was back before the Parole Board again last month.
''For a variety of reasons reflecting Mr Tamati's drug addiction and difficulty managing stress and other situations with which he is confronted, he has resorted to drug use and failed to comply with parole conditions,'' panel convener Judge David Mather said.
''This has jeopardised the support of his family and, in particular, his two young children who live with his partner.''
Judge Mather noted a bed was available at a 12-week rehabilitation course and gave Tamati another opportunity to prove himself.
The prisoner was described as an ''angry young man'' when he was originally incarcerated.
Tamati's associate, Corey Elliman - who was also paroled this year while serving a sentence of four years, 10 months - felt aggrieved at being evicted from a central Dunedin flat in 2015.
He told two people that the man who kicked him out was flush with cash.
''Feel free to rip him off,'' Elliman told them.
The duo, organised by Tamati, had been provided with a key to the property and went to the Maitland St house on July 2, 2015, one wearing a balaclava and carrying a .22 calibre rifle, the other wearing a beanie and a scarf over his face and wielding a knife.
They attacked the victim, who was alone watching TV.
The assailant with the knife punched him as the other man pointed the rifle at him, repeatedly swearing and demanding money and drugs.
As the melee moved to the kitchen, the man with the rifle pressed the muzzle to the victim's forehead, then shot him through the back of the left upper thigh.
The victim dragged himself back to the lounge and lay on the couch with his pet dog while the men ransacked the house.
They got away with only $70 cash and two cellphones.
Tamati's sentence ends in July 2020.
