Updated 12.06PM: The Justice Minister won't be drawn on a call for Teina Pora to receive compensation and requests for an independent body. 

The long-running Teina Pora case has now come to a conclusion with the Privy Council recommending he not be re-tried for the murder of Auckland woman Susan Burdett.

Maori Party co-leader Marama Fox says it shows serious flaws in our system that now won't be picked up without the Privy Council, and an independent commission is needed.

"Use the evidence then to determine what the next steps are. If I'm wrong, the evidence will tell us I'm wrong, but I'm absolutely sure it will tell us there is a need for a shakeup in the justice system."

"There needs to be some sort of recompense for the life of a man that has been lost. Wrongfully convicted, without support, behind bars for 21 years."

Justice Minister Amy Adams won't be drawn on the likelihood of that happening.

"I'm not going to speculate. That's entirely a matter for him, if and when he makes an application we'll deal with it from then."

Adams believes the outcome shows the justice system is working as it should.

"I think it shows the justice system is working as it should, which is that the appeal courts are undertaking the role that they're are intended to take which is to review the decisions of lower courts and change them it there's a concern."

"I think it shows the system is working as intended."

Maori Party co-leader Te Ururoa Flavell says the costly and time-consuming appeals process puts many people off.

"Should there be another way, a tribunal or commission, that can look at these cases as they come through?"

Flavell insists not everyone would have had the support or determination Teina Pora did.

"Cost is a factor, I suppose the belief that people in you is a factor, so we think there's got to be an easier way."

Pora may have a much stronger case for compensation than David Bain, according to Canterbury University Dean of Law Chris Gallivan.

"The court has said effectively the only thing linking him to the crime was a confession, that wasn't worth the paper it was written on."
