Story: Marine invaders

Waitematā Harbour

Waitematā Harbour

The zone most at risk from marine invasives is shallow coastal water, including the intertidal strip. Auckland’s Waitematā Harbour offers a huge area of shallow water and mudflats where a variety of introduced species can thrive. Auckland’s ports handle 43% of New Zealand’s total container trade, with ships arriving from over 200 ports. There are many opportunities for the accidental introduction of species that might do well in the New Zealand environment.
