Papua New Guinea police are asking for witnesses from central Bougainville to the sinking of the inter island ferry, Rabaul Queen, to meet with them in Buka.
The ship sank off Morobe just over a year ago with at least 141 people losing their lives.
A full scale police investigation was launched this month with police teams visiting the island provinces,
Bougainville, and West and East New Britain, that had provided the passengers for the ill fated voyage.
New Dawn FM reports that a 3 person team led by Sergeant Kepae Iubha has already spoken with survivors and the families and friends of victims from the north of Bougainville province.
An earlier commission of inquiry was strongly critical of the ship's owner and government agencies but Sergeant Iubha says it is important for police to carry out their own investigations.
He says they hope to have completed their work in Bougainville in two weeks time.
