Collins has been criticised for her decision to have Justice Ian Binnie's report peer-reviewed by Robert Fisher QC.
She said Binnie's report made assumptions based on incorrect facts and showed a misunderstanding of New Zealand law.
She also accused the report of lacking a "robustness of reasoning" in justifying its conclusions.
The Justice Minister today said she would make the findings public after lunch.
Bain's lawyer Michael Reed said the was a step in the right direction, but they wanted to see it before it was made public.
"I would think we would need just a few days because as I say the Crown's had three months, and even though we're usually faster than the Crown, we would like a few days."
