The Auckland region has over 3000km of coastline, including three major harbours. It is considered a high risk area for marine pest invasion.
Marine pest invasion in Auckland is inevitable. This is due to the large number of recreational and commercial activities operating in the area, especially around the Ports of Auckland.
Invasive marine species pose risks to our environment, economy, culture, as well as social and recreational activities (boating, fishing).
We have a responsibility to:
- prevent the spread of invasive marine species
- minimise the risks to the marine environment by invasive species.
Marine pests to know

How to stop marine pests spreading
Species spread by way of hull-fouling and ballast water.
Here are some tips to help stop the spread of marine pests:
- clean your hull (out of the water) before you leave, including the propeller and anchor
- clean all recreational gear including fishing and diving gear
- check the marine biosecurity rules in other regions before leaving.
The Auckland Unitary Plan will have rules in place when the plan becomes operational later this year.
