Why and how we control weeds

Ā mātou tikanga patu tarutaru

Why we control weeds

We manage 230 species of weeds in the region and control other vegetation.

We do this to:

  • protect and maintain assets
  • maintain infrastructure
  • keep people safe
  • meet our amenity, safety and environmental goals.

The Weed Management Policy sets out our objectives for weed management in parks and open spaces, including road corridors. 

The policy defines a weed as a plant unwanted in a location.

How we decide on weed control methods

The implementation of our Weed Management Policy is supported by two groups:

  • Weed Management Political Advisory Group, who provide oversight on how the policy is being implemented.
  • Weed Management Best Practice Reference Group, who provide external technical advice to council as required.

To contact either of these groups, email our Weed management team.

The implementation of this policy is monitored by two groups:

  • Weed Management Political Advisory Group
  • Weed Management Best Practice Reference Group.

To contact either of these groups, email our Weed Control team.

Current weed control methods

We use a range of methods to control different weeds in different environments:

  • mechanical
  • manual
  • high-pressure steam
  • hot water
  • plant-based herbicide
  • synthetic herbicide (including glyphosate)
  • biocontrol
  • no control (where no weed control is intentionally undertaken).

For more information about these weed control methods, including where and when they are used in Auckland, see Weed control methods or email our Weed management team.

​For examples, see how weeds are controlled in the Māngere-Ōtāhuhu Local Board area.

Weed control projects

Many local boards target specific problem weeds in their areas.

Some recent examples are:

  • Howick – mothplant, rhamnus
  • Waitakere Ranges – climbing asparagus
  • Rodney – climbing asparagus in Takatu.

We also have weed control programmes on the Hauraki Gulf islands and in our regional parks.

Community groups work together in and around local parks.

No-spray register

If you don't want us to spray weeds with herbicide (synthetic or plant-based) on the street outside your property, you can join Auckland Transport's no-spray register.

To register, visit the Auckland Transport website.
