Fiordland is an international treasure with unique but fragile marine ecosystems. The area is rich in marine life including marine mammals, fish, rock lobster and pāua.

Protecting Fiordland

It is vital that we protect this pristine area from introduced marine pests and overfishing.

Marine pests can take over natural environments, displace native species, harm fishing and tourism industries and in extreme cases, affect human health. If new species became established in Fiordland, they could cause irreversible damage.

With increased access and tourism in Fiordland, we also need to protect fish populations and the rich marine biodiversity from overfishing.

MPI has policies and programmes to protect Fiordland, including the Fiordland Marine Biosecurity Programme. If you are visiting the area, you also have a role to play by keeping pests out and following Fiordland fishing rules.

Keep pests out

Marine pests could be carried into Fiordland on vessels or equipment entering the area. Help prevent the introduction of marine pests by keeping your vessel and equipment clean and free of fouling.

Clean Vessel Pass required to enter Fiordland

All vessels traveling to Fiordland waters must hold a Clean Vessel Pass from Environment Southland. This requires you to keep your vessel and equipment clean and free of fouling when entering Fiordland waters.

The pass is a requirement under the Fiordland Marine Regional Pathway Management Plan launched in April 2017.

  • marine equipment is clean (including anchors, anchor wells, propellers, intakes and outlets)
  • your vessel’s hull has a good, functioning antifouling coating.
