  • You must not plant Tasmanian ngaio 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 Tasmanian ngaio 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.

Seeds dispersed by birds.

Competes with native coastal plants. May affect genetic diversity of native ngaio (M. laetum) through hybridisation. Toxic to humans and livestock.
