Weed Management Policy

Auckland's exotic weeds far outnumber its native plant species. We have widespread ones like the moth plant and less common ones like balloon vine or cathedral bells.

Auckland Council adopted a weed management policy in 2013. The policy aims to manage weeds in our parks and open spaces, including the road corridor.

For enquiries about the policy, email the Weeds Management team.

 


The effects of weeds

Weeds can have adverse effects on people and the environment by:

  • causing allergies and health problems
  • damaging infrastructure
  • affecting heritage sites
  • reducing amenity values in public spaces
  • invading sports fields and other playing surfaces (including artificial turf)
  • increasing the cost of asset maintenance and shortening the lifespan of assets
  • negatively impacting on Māori cultural values
  • invading areas of native vegetation, preventing seedlings from regenerating and out-competing native species
  • reducing habitat for native fauna
  • changing ecosystem types and reducing biodiversity
  • reducing water quality
  • impacting on primary industry, e.g. by reducing available grazing area.


Policy objectives

The weed management policy promotes methods that have the least potential for adverse effects.

The policy has eight objectives:

  1. Take an integrated approach to weed management and vegetation control.
  2. Ensure best practice in weed management and vegetation control.
  3. Minimise agrichemical use.
  4. Minimise non-target effects of agrichemical use.
  5. Ensure public health and safety.
  6. Protect and enhance the environment.
  7. Empower the community to manage weeds under the policy.
  8. Deliver weed management and vegetation control which is value for money.


How we control weeds and vegetation

The council uses different weed control methods. Methods vary depending on the species, site characteristics, infestation level and wider landscape characteristics. We choose methods that have the least adverse effects on people and the environment.

Current control methods are:

  • herbicide
  • manual control
  • mechanical control
  • organic herbicide
  • biological control
  • hot water and steam.

Sometimes, we do not control weeds that provide a habitat for indigenous species. An example of this species is gorse.

Together with council-controlled organisations, we control more than 200 weeds in local and sports parks, regional parks, the road corridor and waterways. Many of these are pest plants (environmental weeds).

No spray register

Auckland Transport administers a No spray register. If you do not want them to spray herbicide on the front of your property, join this register and maintain the area.
