The Transport Accident Investigation Commission will release its report into the Rena grounding today.
The Commission's Rena investigation looked into the circumstances leading up to the grounding and not of the oil spill response or salvage involved.
The report will be presented Chief Commissioner John Marshall QC, Chief Investigator Captain Tim Burfoot and Rena Investigator Rob Thompson.
According to a media statement, the Commission's role is to determine the circumstances and causes of accidents and incidents with a view to avoiding similar occurrences in the future and not for the purposes of assigning blame or liability.
Earlier this month the Waitangi Tribunal released its final report on the MV Rena and Motiti Island claims.
Earlier this year, the Tribunal ruled that Ōtāiti (Astrolabe Reef) is a taonga to Māori and that the Crown did not properly consult with Māori in regards to leaving the Rena wreck.
In its report , the Tribunal recommended the Crown take active steps to protect Māori interests in the resource consent process and assist the active participation of affected Māori.
