What you need to know
To help protect our environment:
- you must not breed, distribute, release or sell gorse within the Auckland region
- you must not plant gorse 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 gorse 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
- you must destroy all gorse plants on any rural land in Auckland within 10m of any property boundary that is a) adjacent to land being used for commercial primary production; and b) where the neighbouring land occupier is destroying all gorse on their land.
Transport corridor operators must destroy all gorse on any transport land that is located within the Waitākere Ranges road corridor weed control zone.

Impact on environment
Forms dense stands and outcompetes native vegetation. Alters vegetation composition and native diversity. Reduces food for livestock. Nitrogen fixer. Can impede access to recreational and culturally important sites.
Follow up treated areas 3 times per year. Encourage natural regeneration of native plants or replant treated areas where possible after 2-3 treatments to establish dense ground cover and minimise reinvasion.
Method: Dig out.
Plant parts requiring disposal: Seeds.
Disposal options: Remove to greenwaste or landfill if practical.
Check for presence of agents:
- Gorse colonial hard shoot moth (Pempelia genistella)
- Gorse pod moth (Cydia succedana)
- Gorse soft shoot moth (Agonopterix ulicetella)
- Gorse spider mite (Tetranychus lintearius)
- Gorse thrips (Sericothrips staphylinus).
