Dear Dan
Thank you for your email of 28 January 2025 requesting information relating to
Asparagopsis
taxiformis risk assessment. Your request has been considered under the Of icial Information
Act 1982 (OIA).
You requested the following:
Of the six management options proposed in the risk assessment (national
eradication, local eradication, suppression (reduce the population), pathway
management (slow the spread), gather additional surveil ance data, and no
response), has MPI made a decision on which option it wil pursue? If not, is there a
time frame for such a decision?
Biosecurity NZ has decided to do more surveil ance through the marine high-risk site surveil ance
programme and marine invasive taxonomic service. There is no evidence currently to suggest that
the seaweed
Asparagopsis taxiformis is affecting biodiversity in the areas where it has been found.
Scientists wil be looking out for this exotic red seaweed and continuing sampling as part of regular
surveil ance for marine pests at 12 locations around New Zealand. The seaweed that has been
found looks very similar to the native New Zealand red seaweed
Asparagopsis armata and can
grow among that seaweed.
Boaters, fishers, and divers can help stop the spread of invasive seaweeds by keeping their gear
clear of any seaweed before moving locations and keeping hulls clean.
Should you have any concerns with this response, I would encourage you to raise these with
the Ministry for Primary Industries at
[email address]. Alternatively, you
are advised of your right to also raise any concerns with the Office of the Ombudsman.
Contact details are: Office of the Ombudsman, PO Box 10152, Wellington 6143 or at
[email address].
Yours sincerely
