The Norwegian vessel Edda Fonn, built in 2003, has been modified and outfitted with the dive and hydrographic systems required by the New Zealand Defence Force.
HMNZS Manawanui will deliver 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.
Contributing towards New Zealand’s maritime presence in the region, HMNZS Manawanui will also be supporting government agencies including the Police, Customs, Ministry for Primary Industries and Ministry of Civil Defence and Emergency Management.
