Help control weeds

It's important to follow the right steps when removing and disposing of weeds, to make sure the weeds don't come back in the future.


Identifying weeds

It's important to identify weeds before you remove them, to make sure you're removing the right type of plant, and help you decide which species you should remove first.

Auckland Council's pest plant search includes pictures and descriptions of all the pest plants in the Auckland region.

This tool also outlines the requirements for controlling plants on your property under the Regional Pest Management Strategy.

If you don't find the plant you're looking for here, you can try searching on the New Zealand Plant Conservation Network website, or on the Weedbusters website.

Another option is to collect a sample or take some pictures, and go to your local garden centre for one of their expert staff to identify.

Generally, you should prioritise removing weeds which are:

  • shade tolerant
  • spread by wind or birds
  • climbing stranglers.


Removing weeds

Use our pest plant search to find advice on removing different types of weeds in a way that prevents them coming back.

If your weeding is creating bare ground, replant the area or cover it with mulch as soon as possible. This prevents weeds from re-establishing.

Sometimes weeds may be providing valuable habitat, such as a plant overhanging a waterway and providing shade for spawning. In these cases it's best to remove weeds in stages, to allow natives to establish in their place.

Remember to take care of your personal health and safety when weeding, by:

  • reading the label thoroughly before using any herbicide or pesticide
  • using tools suitable for the size and volume of weeds
  • choosing appropriate clothing and footwear
  • if working in a remote area, using a buddy system or telling someone else where you're going.


Disposing of weeds - bin locations

It's important to dispose of removed weeds responsibly, as many weeds are spread by loose fragments.

You can compost weeds in a closed compost bin, or in special weed bags designed to let air and moisture in and out, but not any plant material.

You may also be able to mulch and re-use the weeds on your garden, depending on the species. Check the pest plant search to see if this is an option.

Alternatively, there are garden companies that will supply you a bin or bag, and collect your garden waste on a monthly basis (for a fee).

Most transfer stations accept green waste, although you should check with your local transfer station before you go.

There are a number of community weed bins in west Auckland for residents to dispose of weeds.


Community weed bin. Permanent locations:

  • 54 Victory Road and 12a Western Road, Laingholm (bin alternates between locations)
  • Huia Domain, 1139 Huia Road, Huia
  • Piha Domain, by bowling club on 15 Seaview Road, Piha
  • 19 Mountain Road, Henderson Valley

  • Kauri Loop Road (next to 734 West Coast Road), Oratia - Second Saturday of each month
  • Kowhai Reserve, 28 Withers Road, Glen Eden - First Saturday of each month
  •  

    If you're transporting or dumping garden rubbish, make sure the weed material is secure so that it doesn't spread during the trip.


    Reporting weeds

    For information on reporting weeds, see report a pest.


    Weed control in your neighbourhood

    If your neighbours also have weed issues, joining together can make the removal work more manageable.

    You most likely won't be able to get everything at once, so target plants with the worst impact on the environment first.

    Define what you're trying to achieve and plan your work to suit this target. Also make sure that your group has the capacity to continue the work that's been started.

    When deciding where to start, work from areas of low to high weed density. Restrict the weeds to a specific area, then work on reducing that area.

    If you're working near a waterway, start at the top and work in the direction the water is flowing.
