Two former Dunedin detectives have been asked to appear before a retired judge as David Bain's compensation bid continues.
Ministry of Justice officials have confirmed retired Canadian Supreme Court judge Justice Ian Binnie will be in Auckland next month to interview Mr Bain, as he assesses the compensation claim.
The former Dunedin man was convicted in 1995 of murdering his family and spent 13 years in jail before being acquitted in a 2009 retrial.
An application for compensation for wrongful conviction from Mr Bain was received by former minister of justice Simon Power on March 25, 2010.
A ministry spokesman said ``Justice Binnie's role is an independent one and includes deciding the best process for assessing the claim''.
