What you need to know

To help protect our environment:

• You must not breed, distribute, release or sell bushy asparagus. As bushy asparagus is a National Pest Plant Accord species, these restrictions apply within the Auckland region and across the whole of New Zealand.
• You must not plant bushy asparagus within the Auckland region, unless you are transferring an existing plant on your land to another location within the boundaries of the same property.
• You must destroy any bushy asparagus on land that you occupy if it has been planted in breach of the above rules and you are directed to do so by an authorised person.

If you occupy land within the buffer area of a park where bushy asparagus is being managed, and Auckland Council has carried out initial destruction of bushy asparagus on that land, you must undertake follow up the destruction of all bushy asparagus on that land.

View a map of park buffers where this applies. To find out more about how we’re protecting Auckland’s parkland from pest plants, visit our pest plant buffer pages.

Auckland Council will control bushy asparagus at all sites within the Aotea/Great Barrier Island group where it is known to occur.

If you see bushy asparagus anywhere on Aotea/Great Barrier Island group, please report it to Auckland Council at pestfree@aucklandcouncil.govt.nz.
