Better ways to stop marine pests?

Working together on better ways to stop marine pests in the top of the North Island.

Infected hull keel and starboard side

To protect the coastlines we all love, the four northern-most regions are considering new marine biosecurity rules.

As the movement of boats increases, so too does the risk of marine pests spreading.

With support from Biosecurity New Zealand, four regional councils – Northland, Auckland, Waikato and Bay of Plenty Toi Moana – are exploring whether having hull-fouling rules that are applied consistently across several regions would be a better way forward.

Your feedback

Earlier this year, we asked the public whether we should develop consistent rules across these four regions and, if so, what those rules might look like.

A two-month feedback period closed on Friday 24 May 2019 – thank you to everyone who took the time to have their say.

You can now read the feedback summary to find out what people said.


You can also read the consultation discussion document to find out more about the problem and the options being considered.

What happens next?

The feedback has provided useful insight toward our approach to marine pest pathway management and has been provided to the four councils involved.

Our next steps (and indicative timings) are:

  • Late 2019 – staff from the four councils, along with Biosecurity NZ, will work together to outline benefit, impacts and costs of the options and develop a preferred option for managing marine pest pathways.
  • Early 2020 – The preferred option will be presented to the councils for consideration and their decision.

If councils decide to develop a formal proposal for an inter-regional marine pathway plan, there’ll be further opportunity for input.
