Overview

HMNZS Manawanui delivers the ability for diving and hydrographic specialists to embark and conduct specialised operations such as surveying of lakes, coastlines and harbours, underwater explosive disposal, mine counter measures and underwater search and salvage. Possible missions for the ship includes surveying harbours and approaches after a natural disaster prior to larger support ships landing support equipment and personnel, providing support to the ongoing mission to eradicate explosive remnants of war in the South Pacific and salvage operations to find and recover submerged objects.

Contributing towards New Zealand’s maritime presence in the region, HMNZS Manawanui also supports government agencies including the Police, Customs, Ministry for Primary Industries and Ministry of Civil Defence and Emergency Management.
