Alan Hall says he still has a positive outlook on life despite spending 19 years in prison.
Hall served 19 years in prison for a murder he didn't commit - with the Crown admitting this week that he was the victim of a miscarriage of justice.
The case centred around the violent home invasion and killing of 52-year-old Arthur Easton in his Papakura family home.
Hall was released from jail in the 1990s but sent back for breaching his parole in 2012, and was only let out of prison in March this year.
The now 60-year-old's lawyers are now pushing for an investigation into how his case was handled.
But Hall has told AM that he will continue living his life to the fullest.
"Yesterday was yesterday, today is today… right this very second I'm living in the moment," he said.
Sharing a laugh with host Melissa Chan-Green on Thursday, Hall suggested Tom Cruise could one day play him in any future movie made about the case.
In quashing Hall's conviction on Wednesday, the Crown admitted it was "trial gone wrong" and a substantial miscarriage of justice.
Hall's brother Geoff said the family got what they needed. The family has been resolute in its support of Alan - including their mother Shirley up until her death in 2012.
"Mum has always been the critical part of our team from day one and it's her mantle that led the way for us moving forward through the years, and she tried everything for Alan," Geoff told AM, sitting alongside his brother.
"She had a lot of faith in Alan and the justice system; she felt it's got to see the truth along the way.
"In 2012, when she passed, she handled the mantle over to me to carry forward and on one of her last breaths, I said, 'I promise I will bring justice.'"
Private investigator and former police detective Tim McKinnel, who helped clear Teina Pora of his wrongful murder conviction in 2015, played a massive role in getting Hall's case before the Supreme Court. McKinnel was asked to take on the case and "saw something terrible had gone wrong".
McKinnel told Chan-Green while there had been improvements across the criminal justice system, "whether they are sufficiently robust to prevent this sort of thing happening again, I'm not so sure".
He said it "absolutely" wasn't too late to reopen the investigation into who actually killed Easton.
"There's still a surviving body of evidence from the case and there are lots of unanswered questions.
"There is no reason that this case can't be reinvestigated. The Easton family deserves that."
Crown Law's top authority was launching an investigation into Hall's case. The prosecution "fell well short of meeting the legal requirements of a fair trial", the Solicitor-General said in a statement.
