Undaria Pinnatifida (Wakame) is an invasive species in New Zealand.
It came in our country in the ballast water of cargo ships and it has spread throughout the coastal waters.We collect this seaweed only from mussel farms which are man made structures and not from natural surfaces .Undaria colonizes all hard surfaces, displacing native seaweed and altering the ecological balance in marine environment. For mussel farmers, the Undaria causes many issues by displacing and chocking mussels, reducing harvesting productivity and increasing fuel usage and maintenance costs.


At Waikaitu, we believe in third party, Independant testing, verification and licensing.
