An inquiry report has determined that the sinking of a New Zealand navy ship off the coast of Samoa was caused by human error, specifically due to the crew mistakenly leaving the vessel on autopilot. The inquiry revealed that the HMNZS Manawanui hit a reef, leading to its sinking. Additional findings pointed to sexist comments directed at the captain as part of the problematic crew dynamics. This incident highlights the critical need for improved training and adherence to safety protocols within the navy.
