Disaster officials in Papua New Guinea are calling on relatives of those who may be missing in the Rabaul Queen sinking to come forward to help ascertain the exact number of people who lost their lives in the tragedy.
The ship sank off Morobe nearly two weeks ago
There have been estimates of about 100 to more than 300 people missing.
Our correspondent in Lae, Oseah Philemon, says the disaster centre has published lists of those on the manifest and are asking relatives to check if their family members were among those who drowned or were rescued.
"There may be people who are missing who are not actually on the list and were never on the manifest. So this is the real problem now and once those people come forward with the names - they have given a week to do this and after that then a declaration will be made about the final figure on the actual missing, presumed dead and the survivors."
