Mr Bain's advocate Joe Karam said the blame for the new delay and its associated costs could be placed squarely on Mrs Collins, who "secretly" asked for a peer review of an initial inquiry by former Canadian Supreme Court judge Ian Binnie.
"It's a great shame for David, for me, for the New Zealand public in general," he said. "It's extremely disappointing that this should happen from a number of points of view, not least of which is the taxpayers who now have to cough up between half a million and a million dollars."
Mr Karam said he was more confident of a positive outcome from the new review because he believed Ms Adams would be more principled than her predecessor and would not "bulldoze" any findings.
Mrs Collins shot back at Mr Karam yesterday, saying she could never have awarded compensation based on a faulty inquiry.
"I stand by everything I said and did," she told the Herald. "I did exactly what I had to do."
Justice Binnie found that Mr Bain was innocent "on the balance of probabilities", but the peer review by QC Robert Fisher found numerous errors in his findings.
Mrs Collins said the main reason for a delay in the five-year process was the decision by Mr Bain's side to seek a judicial review of the Government's handling of the case.
Ms Adams said starting the process again was "highly regrettable" but she did not blame it on her predecessor.
She said Cabinet did not have reliable information to make a decision which would withstand the close scrutiny that Mr Bain's case attracted.
"I cannot make a decision based on what is in front of us." Mr Bain could receive a payout of at least $2 million, not including pecuniary losses from his time in jail. Mr Bain was convicted of killing five family members in Dunedin in 1995, but was freed from prison after being found not guilty in a retrial in 2009.
