The HMNZS Manawanui sank off the south coast of Upolu Island on Saturday after running aground, catching fire, and capsizing. Some crew members are back in New Zealand, while teams from the New Zealand Defence Force and Maritime NZ are beginning to assess the situation and plan salvage operations.
Brent Ross, who runs a surf adventure company on Upolu, reported seeing debris and fuel oil near the wreck. He expressed concern for local fishermen and the marine environment since many locals rely on fishing for their livelihoods.
Experts say it is unclear how much damage the sinking will cause. Factors include the seabed type, water depth, weather conditions, and the chemicals on board the ship. Coastal science Professor Chris Battershill, who worked on the Rena cleanup, noted that quicker actions by agencies can help minimize harm.
The Defence Force confirmed that the ship carried standard marine chemicals and Automotive Gas Oil, a light diesel fuel. Professor Battershill mentioned that lighter oils can evaporate quickly, potentially reducing toxicity over time. However, if the oil washes ashore, it may cause immediate contamination.
While the Manawanui has third-party insurance for salvage and cleanup, it is not covered for replacement due to high costs. Defence Minister’s office stated that insurance spending has not changed for the ship.
Labour Party spokesperson Peeni Henare has called for better insurance for defense ships in the future since the navy’s vessels often face operational challenges.
Later this month, leaders from Commonwealth nations will meet in Samoa for the CHOGM summit. This situation could impact how New Zealand is viewed internationally, and Henare emphasized the need for a strong response to ensure a good reputation.
