# New Zealand Navy loses HMNZS Manawanui after grounding off Samoa

Standfirst: HMNZS Manawanui ran aground and later sank off Samoa, and all 75 people on board were rescued, according to New Zealand officials.

The Royal New Zealand Navy suffered its first accidental loss of a vessel since World War Two on 2024-10-05, after HMNZS Manawanui ran aground on a reef off Samoa, caught fire and later capsized and sank.

The evidence packet says the specialist diving and ocean-imaging ship came into trouble about one nautical mile from Upolu while conducting a reef survey. Bad weather made the emergency more difficult to manage, with strong winds and currents pushing life rafts and rescue boats toward the reefs and making the operation “challenging,” according to military officials quoted in the report.

All 75 people on board were evacuated onto lifeboats and rescued early the following day. That included seven scientists and four foreign military personnel, who were later accommodated in Samoa before being flown back to New Zealand. The rescue is the most important immediate fact in the incident: despite the fire, listing and sinking, no lives were lost from the crew or passengers aboard the ship.

The vessel’s final condition underscores the scale of the loss. By Sunday morning local time, smoke was visible and the ship was listing heavily. Later that morning it was reported to be below the surface. Defence Minister Judith Collins described the event as “a really sad day for the Navy,” while stressing that the crew’s training and courage helped ensure everyone came through safely.

The cause of the grounding remains unknown in the evidence packet and is expected to be investigated. Officials also noted that the area had not been surveyed since 1987, a detail that may prove relevant to any later inquiry but does not itself explain the accident.

Beyond the immediate rescue, the loss carries symbolic weight. The BBC source says the Manawanui is the first New Zealand naval vessel to be unintentionally sunk since the country’s participation in World War Two. That makes the incident exceptional in modern peacetime service and likely to draw scrutiny over operations, ship handling and whether the survey mission was adequately supported.

The packet also says military officials were turning toward salvage efforts and assessing environmental impact after the sinking. Those follow-up tasks matter because the incident was not only a maritime emergency but also a potential ecological risk in Samoan waters.

What can be verified now is straightforward: the ship grounded, fire and sinking followed, all aboard were rescued, and New Zealand lost a naval vessel in one of the rarest kinds of peacetime incidents a navy can face.
