The King of Tonga has received the report on the sinking of the ferry Princess Ashika last August which took 74 lives last August.
The Royal Commission of Inquiry office says the report was presented by the three commissioners this morning.
The final report follows nearly six months of investigations in Tonga where the commissioners heard repeatedly that the ship's purchase was marked by lack of process, no due diligence and use of forged documents.
The inquiry also heard that many government departments were dysfunctional and there was discord between members of the Shipping Corporation of Polynesia Board.
Relatives of those who perished with the ship are hoping the report will address the facts of the disaster and who is responsible.
