Prevent pests from spreading

Minimise the spread of pests on land and in water by thoroughly checking and cleaning your boat and gear. Keep your favourite spots pest-free for future generations by following these guidelines:

  • clean your hull out of the water before you leave, including the propeller and anchor - see guidelines for hull cleaning
  • clean all recreational and boating gear
  • if leaving Auckland, check the marine pests website for biodiversity rules for other regions.

Check the marine pests website for more marine biosecurity information.

Kawau Bay is a relatively pristine and highly diverse coastal ecosystem.

You’ll find sponges and ’red stones’, (or rhodolith, a kind of coralline red algae) in the channels between the islands in the bay and these extend towards the mainland in some areas.

The protection area covers part of the ‘red stone’ bed that extends into Kawau Bay. Protection isimportant for creating shelter and food sources for marine organisms.

Martins Bay historically contained many horse mussel beds that may still be present. Horse mussels play an important role in filtering water and maintaining a healthy marine ecosytem.

Mussel beds, kelp forests and sponges, provide nursery habitats for young fishes - particularly snapper and scallops.

The area is known to have been a nursery area for mako/sharks.

The Hauraki Gulf Marine Park/Tīkapa Moana/Te Moananui-ā-Toi has a rich history of human settlement. It includes the earliest places settled by Māori.

The area has supported the physical and spiritual wellbeing of mana whenua for centuries. Mana whenua use tikanga/customs that care for and protect the environment when collecting kaimoana/seafood. Mana whenua is the iwi or hapū that has customary authority in an area.

Iwi with significant connection to the Kawau Bay area include Ngāti Paoa, Ngāti Maru, Ngāti Tamaterā, Ngāi Tai ki Tāmaki, Te Kawerau a Maki, Ngāti Manuhiri, Ngāti Wai, Te Rūnanga o Ngāti Whātua, Ngāti Hako, Ngāti Te Ata, Ngāti Rehua, Ngāti Whanaunga, Ngātiwai.

Protection areas

These protection areas began in 2025. They were initiated from the Government response to the Sea Change – Tai Timu Tai Pari Hauraki Gulf Marine Spatial Plan. Sea Change was developed collaboratively by tangata whenua, environmental groups, and the fishing, aquaculture and agriculture sectors of the Hauraki Gulf between 2013 to 2017.
