Unwanted Organisms

In New Zealand, an unwanted organism is any species officially designated under the Biosecurity Act 1993 as potentially harmful to the environment, human health, or natural resources. This designation is made by the Ministry for Primary Industries (MPI) and listed in the Unwanted Organisms Register. Once declared unwanted, it becomes illegal to sell, propagate, or distribute the organism without permission. These organisms are often targeted for control, containment, or eradication through national or regional pest management programmes.
