Mr Pora will attend Joseph Parker's 13th professional bout in Auckland tonight against American Jason Pettaway.
"I used to watch him fight inside, in the place where I've been for the last 22 years," Mr Pora told One News today.
"To get to meet him [Parker] has been an honour and a privilege."
Parker was pleased to have Mr Pora in his corner.
"I definitely have sympathy for Teina and what he's been through," he said.
"Twenty years in prison's a long time."
Despite his lawyer saying Mr Pora would not be speaking publicly "for the foreseeable future" given there was still a chance he could face a third trial for the murder of Susan Burdett, he shared his feelings about Tuesday's Privy Council decision.
"I can just be happy and be myself."
He said the last two days "have been crazy".
"[I've] just been relaxing especially with my daughter and my grandson - that will be the most precious thing that a father can want in their life."
Mr Pora revealed he had been training "all of his life" in prison and had plans to step into the boxing ring himself.
It is understood his debut bout would be against a police officer within the next few months.
