The Government is set to announce if it's approved a compensation bid for Teina Pora, who could receive as much as $2 million for wrongful imprisonment.
Mr Pora spent more than 21 years in prison for the rape and murder of Auckland woman Susan Burdett, before his conviction was quashed last year by the Privy Council in London.
A retrial was ruled out.
Mr Pora put in a claim in April 2015 for compensation for wrongful conviction and imprisonment and could be claiming more than $2m.
Cabinet guidelines indicate Mr Pora could be asking for about $2.1m as compensation for loss of liberty and emotional harm is calculated on a starting point of $100,000 for each year in prison.
Newshub reported on Tuesday that Cabinet has approved $2m compensation.
Neither Mr Pora's lawyer Johnathan Krebs or Justice Minister Amy Adams would confirm the report.
However, a spokesman for Ms Adams confirmed she would make an announcement on Wednesday.
