David Bain wants the rifle he was accused of using to kill his parents and three siblings in Dunedin in 1994.

Bain, 37, was cleared of the murders in June after 13 years in jail and a long retrial.

One News reported last night that Bain lawyer Helen Cull, QC, had confirmed that after the retrial the defence team applied to get many of the 500 exhibits - including the rifle - to ensure they were not destroyed or lost.

One News said the prosecution was holding on to the exhibits until Bain's claim for compensation for his time in jail had been dealt with.

The exhibits are in Christchurch, where the retrial was held.
