The HMNZS Manawanui was the first ship New Zealand lost since World War II, and was one of nine ships in the country's small navy fleet.

Summary

The New Zealand navy ship HMNZS Manawanui sank near Samoa during an ocean floor mapping mission after crew errors left it on autopilot, causing it to accelerate into a reef.

The vessel, lost in October, was the country’s first navy shipwreck since WWII. A military inquiry blamed human error, with crew failing to disengage autopilot.

The ship carried 950 tons of diesel, raising environmental concerns, though fuel tanks appeared intact.

No fatalities occurred, but minor injuries were reported.

Social media criticism unfairly targeted the ship’s female captain, prompting defense officials to denounce sexist remarks. Salvage efforts are ongoing.
