The coroner will not resume an inquest into the sinking of the Kotuku in Foveaux Strait in 2006, with the loss of six lives.
Coroner Trevor Savage says he has decided not to resume the inquest because two investigations have already covered the significant issues surrounding the sinking.
The coroners inquest was adjourned in May 2006 because several independent investigations were underway.
Mr Savage says he is satisfied the Transport Accident Investigation Commission report and a similar one carried out by Maritime New Zealand have identified the cause of death.
The two reports had slightly different conclusions, but did establish why the boat sank and made safety recommendations.
