Ōkahu Bay Mussel Reef Restoration

Tēnā tātou e te whānau, over the next few days you may see some activity in Okahu Bay.

We are proud to announce that Ngāti Whātua Ōrākei and the Revive Our Gulf project are working on a study that looks to build on past efforts to re-seed kūtai / mussel beds in Ōkahu Bay. This is just stage one of the works where the project team is working with Ports of Auckland to prepare a section of the bay for mussel beds using “up-cycled” shell hash from maintenance dredging.

A platform measuring 50m x 50m and approximately half a metre deep will be deposited on the inside of the breakwater piles. The shell hash will be extracted from the Rangitoto Channel just out from Ōkahu Bay. Using a shell substrate for the mussels beds is thought to improve survival rate and increase available habitat for juvenile mussels and other organisms to settle on.  We plan to deposit the mussels before the end of the year.

Exciting stuff e te whānau, keep a look out for more updates and information coming soon.
