Some action's already been taken to try and prevent a repeat of the HMNZS Manawanui sinking.
The navy vessel went down nearly two months ago after hitting a reef during a survey of the Samoan coast.
The interim Court of Inquiry report's found it was caused by a series of human errors - with the crew failing to turn off the ship's auto-pilot when they were supposed too.
As they tried to slow it down, they instead accelerated faster into the reef.
Defence Minister Judith Collins told Heather du Plessis-Allan it’s incomprehensible.
“Except that we also know that sometimes even with the best will in the world, people make mistakes, and then someone else makes a mistake, and it becomes, in this case, a lost ship and people’s lives being unnecessarily put at risk.”
