From rubbish to rodents: five things you can do to help protect the Hauraki Gulf this summer
As Aucklanders prepare to make the most of long summer days on the water, it’s worth remembering the Hauraki Gulf is more than just a playground; it’s home to some of our most treasured wildlife and island sanctuaries. With more boats expected on the water, Auckland Council is urging boaties to do their bit to protect this unique environment – here’s how you can help:
One of the most pressing threats is the spread of exotic caulerpa, a fast-growing seaweed that smothers the seafloor, displacing marine life and likely impacts fishing, boating, and cultural activities.
It has been found at Aotea/Great Barrier Island, Kawau, Rakino, Hauturu/Little Barrier, Mokohinau, Coromandel and Waiheke, this super-spreader must not be allowed to spread further. Boaties can help by checking anchors and equipment, avoiding anchoring in known areas and following the Control Area Notices (CAN) rules. To learn more about caulerpa and CANs visit the Ministry of Primary Industries website.
If you are boating in the Hauraki Gulf check out the new Marine Protected Areas that came into effect on 25 October and follow them.
Rodents, ants, skinks and other pests are another serious risk. Pest-free islands like Rangitoto, Motutapu, Tiritiri Matangi, and Little Barrier are vital sanctuaries for rare species like takahē and shore plover. But those pests can easily hitch a ride on shoes, gear, or boats and once established, cause devastation. That’s why visitors are urged to check, clean, and close before heading out. Clean clothing, footwear and camping gear thoroughly, scrub soil from shoes, and make sure bags and food are sealed tight.
