Asked if he held any resentment for his incarceration, Iti replied: "Not at all".
"You just move on ... kaore oku raruraru (I don't have any problems with it)."
Iti said he was saddened by the number of young Maori men he met while in jail and he plans to work more with the Department of Corrections to aid inmates.
He spent time working in the prison's garage earning 20 cents an hour before moving to a prison farm where his pay doubled to 40 cents an hour.
Iti was also looking forward to writing a book about being a political prisoner and training for the Iron Maori event that will take place in the Hawkes Bay later this year.
Iti's lawyer Russell Fairbrother said he had applied for leave to appeal to The Supreme Court.
"The Crown has responded and the court is now considering whether to grant leave."
"There are two considerations; one is a point of law and public interest - we think we cover both bases."
Iti's son, Wairere Iti, told Newstalk ZB this morning said the process including his father's incarceration and trial had been six years in the making.
"There's still the Supreme Court and that kind of thing, and it has at times been quite trying - the sentencing particularly."
The Parole Board decision said Iti had shown leadership qualities in prison, and was described as a role model prisoner.
"Iti spent his time in prison working with other inmates. He was in the Maori focus unit there, so ... he was able to contribute to that kind of stuff really easily, obviously, and be a good influence to some of the inmates," Wairere Iti said.
Iti's co-offender, Te Rangikaiwhiria Kemara, will also be released next week.
Urs Signer and Emily Bailey were also found guilty of firearms charges and were sentenced to nine months' home detention at their home in Parihaka, Taranaki.
Earlier, a photo was posted on Twitter of Iti enjoying a cappuccino, with the caption: "An early rise this morning to meet with my whanau in kihikihi. It feels good to be out ... Now where is my cappuccino."
