What you need to know

To help protect our environment:

  • You must not breed, distribute, release or sell iceplant. As iceplant 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 iceplant 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 iceplant 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.

Coastal cliffs, sand dunes.

Seeds dispersed by mammals. Vegetative spread from stem fragments.

Smothers and competes with native vegetation and modifies soil chemistry. Reduces germination and survival of native vegetation and decreases native species’ richness. Affects genetic diversity of related native species through hybridisation.

Site Management

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.
