A report on how Cook Islands authorities handled a triple shooting in October last year has been completed.
Escaped prisoner Chris Rimamotu killed his former wife, Mary Dean and her new partner, Roger Tauarea, before killing himself.
A former Australian Federal Police Assistant Commissioner Denis McDermott and former Cook Islands police commissioner Tevai Matapo, were asked to investigate the shooting's circumstances.
They interviewed 100 witnesses, and their report is said to detail the primary causes and actions that led to the shooting, and the actions of the police, corrections, health and customs agencies.
It also reviews Cook Islands firearms laws and identifies recommendations to avoid a repeat incident.
The report was handed to Prime Minister Henry Puna on Friday, who would take it to cabinet on Tuesday before handing to the police and justice ministry.
A spokesperson for Mr Puna said it was likely to made public after that.
