Police say exhibits from the Bain case have to remain available for any other inquiry that might be contemplated.
David Bain's defence team has made an application to be given some of the exhibits from the acquitted man's two murder trials.
That is understood to include the rifle used to kill Mr Bain's five family members, which he owned at the time of their deaths in Dunedin in 1994, and personal family items including photo albums.
Exhibits normally remain with the court or police until all avenues of appeal have been exhausted.
Further action may be lodged though the justice system regarding possible compensation for Mr Bain, but a decision on this has not yet been made.
