New Zealand's defence force has launched a formal court of inquiry into the "shocking" sinking of the HMNZS Manawanui, which sank after striking a reef in Samoa's south.
The embarrassing disaster is NZ's first naval loss during peacetime, and first since World War II.
It has also started the clock on an urgent clean-up job, and investigation into whether the wreckage can be salvaged from the sea floor.
