MPI has a proposal to considerably extend the Caulerpa seaweed restrictions at the Barrier from the current areas (Whangaparapara, Blind Bay Tryphena) where there is no anchoring, movement in or out and fishing to the area shown:


Reaction from those affected has already caused MPI to "reconsider" and I have just received this notice:

Kia ora koutou


Community hui in Claris, Aotea

This update is to remind you of the planned community hui in Claris on Monday (19th) and to let you know that there will be an option to listen to the session online via Zoom. 

The meeting will be attended by Mana Whenua and other members of the dual response Governance group, and the Biosecurity New Zealand response team.

Since it was first mentioned that extending the Controlled Area Notice over the south western coastline of Aotea was under consideration, we have received a lot of feedback. We have heard the concerns raised about potential effects on individuals and businesses, and, as a result, the Aotea Caulerpa response governance group is reconsidering the proposal to extend the area under controls.

We will discuss our plans to greatly increase education and communications encouraging people to do the right things voluntarily to prevent the spread of Caulerpa.

In addition, we are progressing a Caulerpa research programme which will support future management of this seaweed. There is no intention to 'give up' on managing Caulerpa in future, but there is an acknowledgement that we do not currently have the tools or treatments to get rid of it. This research will both help us understand the problem better and enable us to test some new tools. 

These issues will be discussed in more detail at Monday’s community hui.


Where: Claris Sports and Social Club
19 Whangaparapara Road
Claris, Great Barrier Island
When: Monday 19 September 2022
5.30 - 7.30 pm


There will be an opportunity for those attending the meeting in person to ask questions and provide feedback.

For those who cannot attend in person, the meeting will be streamed on Zoom. However, it will not be possible for those viewing the livestream to speak.

If you plan to attend via Zoom, feel free to submit any questions to us ahead of the meeting through our email:  mailto:[email protected]" rel="nofollow - [email protected]  

We will endeavour to answer questions through our presentation and it is highly likely your queries will be answered during this, or the open floor session after. We can answer any questions by email after the meeting if you have issues outstanding.

The issue here for me as a non-resident boating user who spends weeks at a time in the area is not whether we need to do what we can to stop the spread of this seaweed, we do, but that MPI seem to have done very little (absolutely nothing I can see) at this stage following the closure of the original areas. There are no management or eradication measures currently in play in those areas, or even identified as being usable in the future.

If they now just close a larger area, still without active measures to do anything about Caulerpa, then what we are looking at in the longer term, maybe even only another 12 months, is the complete closure of the western side of the barrier to visiting boaties and fishermen. This would obviously be catastrophic for many businesses and people who live there who rely on being able to fish and move around on the water to survive.

A temporary closure of the original areas while MPI came up with a plan is one thing, the complete closure, because there is actually no management means available, is another thing altogether.

How can MPI stop or slow the spread?? everything moves with tides and the question for me is how did it get here considering ballast tanks cannot be emptied with in NZ waters unless treatment plant onboard.

Not to knowledgeable on this issue/area, however the cynic in me asks whether this could be the implementation of a reserve by stealth.
Thoughts from those in the know?

Now a Survey has popped up that has not been promoted other than to the residents group via their Facebook page. However anyone interested can complete it.

Please complete!

I watched the Claris meeting via a barely functional zoom link, video was fine but the audio was hopeless. Even the primary speakers using microphones were barely audible and anything from the floor was just a mystery! Gave up following the official presentation, half way through the "questions from the floor".

MPI have beaten a hasty retreat from the proposals shown in the map and now are proposing extending the time period for the existing CAN by another 6 months from the expiry date of 30 September with a couple of ammendments.

They will change the "no lifting your anchor" to a straight "no anchoring" in the closed areas (Tryphena, Whangaparapara, Blind Bay) and change the "No Fishing" to allow fishing FROM SHORE ONLY.

They will strengthen the public awareness campaign and increase on water compliance.

They continue to look at research on both eradication and what the actual longer term impact of the infestation is.

Their own technical advisory group have told them it is not possible to eradicate it at this time as there are no methods available that can be used with the scale of the current infestation already.

They tried killing areas with salt applied at 50Kg per square metre then covering the area with a blanket and this was successful at killing the area covered but, it killed everything else as well. The area of investation in Blind Bay alone is already too large for it to be economically feasible of even practical to use this method anyway, apart from the dire effects on the rest of the ecology!

 I won't comment on the issues raised by the local attendees at the meeting as I couldn't hear them properly so it would be a disservice to even provide a summary of the answers I could hear. My overall impression was that there was a lot of dissatisfaction with continuing the existing closure at all.

Overall, they have no usable method of control or eradication, but still want to remain in a holding pattern for another 6 months, I suspect we will see them back with a better backed closure of a larger area in another 6 months!

This attempted extension of the area was based on detection of smaller areas of Caulerpa at 4 locations outside the existing closed areas, 2 of them fairly close to the existing areas and 2 further north on the coast but south of Bowling Alley bay. I heard nothing in the presentation about attempting to eradicate these smaller infestations.

It’s not subtle. For every square metre of weed, you need 50 kilograms of coarse-grained salt crystals—600 kilograms for every three-by-four-metre test plot. Jeff Cleave went out on the NIWA boat to help with the application, upending the 25-kilogram bags into a hopper connected to a PVC pipe, while divers on the bottom angled the hail-like flow of salt onto the algae, then stapled a tarpaulin and hessian mats over the top.

Do nothing !! Save time and $$. Weed will move where it wants ! Why do people think that it can be stopped ? Nature will take it's course.

Inevitable really. I bet it's in other places around the east coast north island too. By the the time they actually find it, it has to have been there to quite a period.

BOI and virtually all of the North Island is going to be ****ed soon.

Everyone going waa waa waa, we need more $$$ ! . ( seems to b the in thing these days ) No one yet to say how to stop spread , because you can not stop it. Better to spend $$ else where...much like climate warming !.

Need accept its there and treat it like didimo? at the lakes wash anchors  etc before moving off? but once disturbed it will get in currents and spread,apparently we have 2 or 3 native species.

I believe fish wont eat it as its poisonous to them, kina wont eat it.

May of been here 5yrs or more,just like the Waikato river asian cockles,now think they have been there 2 or 3 yrs.

Another bio security/mpi failure

More than 1000 hectares of the Bay of Islands moana now has a fishing and anchoring ban due to new government biosecurity controls and a mana whenua rāhui in the wake of caulerpa being found across 200 hectares of the iconic New Zealand visitor marine destination. The bans took effect yesterday, 12 June.

Hopefully the mana whenua, as guardians of the NZ coastline will find a solution without needing monetary grants from the other 85%.

Think I heard somewhere they, the marine scientific community, are going to try placing chlorine tablets around the area and then covering that area with a tarp/cover so hopefully, the dissolved chlorine only affects the area concerned. Believe it to be only a trial at present. Here's hoping.

They tried salt by the ton then covered with sacking,but too costly

The salt application method is an absolute joke. If you have to apply 50 kg/m2 then that is 500,000 kg/ha (10,000m2) = 500 tonne/ha, with ag salt currently costing $330/tonne (Ballance Agri Nutrients - they may be able to get it a bit cheaper but it won't be much) this works out at $165,000/ha for the salt alone, plus probably that much again for labor, boat hire etc etc. If we say conservatively the cost of treatment is $300,000/ha coupled with the likelihood that there is probably several hundred hectares of infestation area already spread far and wide between Great Mercury Island and the Bay of Islands and growing all the time (it will spread faster than the area that can be treated - also this is something that will be run and administered by the public sector, so don't expect anything to go quickly or smoothly). 

The numbers are just mind blowing. It has never been eradicated from open water anywhere in the world, only place from what I have heard where an infestation was in a small enclosed waterway.
