What you need to know
To help protect our environment, after the RPMP has been operational for two years, you:
- will not be allowed to breed, distribute, release or sell Canary Island ivy within the Auckland region.
- will not be allowed to plant Canary Island ivy within the Auckland region, unless you are transferring an existing plant on your land to another location within the boundaries of the same property.

Native forest, roadsides.
Seed dispersed by birds. Vegetative spread locally. Human-mediated dispersal through dumping of garden waste.
Impact on environment
Forms dense mats, preventing native regeneration, affecting ground invertebrate communities and providing habitat for rodents. Can cause contact dermatitis.
Cut and pull vines away from desirable trees and native plants before foliar spraying. 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: All parts.
Disposal options: Compost stems and roots in a composting weed bag or remove to greenwaste or landfill if practical.
Biocontrol is currently not available for this species.
