Justice Minister Judith Collins will release the controversial David Bain compensation reports this afternoon.
Pressure has been building to make public the report completed by retired Canadian judge Justice Ian Binnie in September.
Collins said a peer review by Robert Fisher, QC, must be released at the same time.
Binnie and Collins have publicly traded blows over what was in Binnie's report on the compensation bid.
He had concluded Bain was innocent on the balance of probabilities of the murder of his parents, two sisters and brother in Dunedin in 1994.
Collins says Binnie made "significant errors", misinterpreted evidence and went "well beyond" his terms of reference.
She has asked for his report to be peer reviewed by Fisher. She was due to receive the review today.
Binnie, who was paid $400,000 for his work, has said Collins was playing politics and it was unfair that Bain had not been allowed to see the report.
Bain is seeking compensation for the almost 13 years he spent in jail after being convicted in Dunedin in May 1995.
He was acquitted at a Christchurch retrial in 2009 and could get about $2 million, but the Government is not obliged to pay compensation.
