What you need to know

To help protect our environment:

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

Forest, woodland, forest margins, riparian areas, roadsides, regenerating scrub, pasture.

Seeds dispersed by birds, water, wind and possibly possums. Human-mediated dispersal through contaminated vehicle and soil movement and dumping of garden waste.

Forms dense stands, excluding native vegetation and suppressing seedling recruitment. May affect habitat availability and food resources for native and exotic fauna. Reduces pasture and plantation productivity, causes photosensitisation and dermatitis in livestock.

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.
