Ballast Water Requirements for fishing vessels

Fishing vessels on an international voyage that take on water or use brine to maintain stability must comply with Part 300

New Zealand’s Marine Protection Rules Part 300: Ballast (Part 300) set out rules for the control and management of ships’ ballast water. Part 300 aims to prevent harmful aquatic organisms and pathogens entering New Zealand’s marine environment. If harmful aquatic organisms become established, they can severely harm our marine environment. Pathogens in ballast water can also present a risk to human health and marine ecosystems. 

Part 300 gives effect to the provisions of the International Convention for the Control and Management of Ships’ Ballast Water and Sediments 2004. 

This position statement clarifies how Part 300 applies to: 

  • New Zealand‑flagged fishing vessels within New Zealand's jurisdiction on an international voyage to or from New Zealand, and 

  • foreign fishing vessels within New Zealand's jurisdiction on an international voyage to or from New Zealand. 

Fishing vessels on an international voyage that take on water or use brine to maintain stability must comply with Part 300

When on non‑fishing international voyages, fishing vessels that use refrigerated sea water tanks (RSW) or non‑dedicated ballast water tanks for stability, are considered to be carrying ballast water in ballast water tanks. Therefore, these vessels must comply with Marine Protection Rules Part 300 when on international voyages.
