Responsibilities for Managing Pests and Weeds

Biosecurity responsibilities are shared between central government, regional councils, industry and landowners. This page will provide readers with a better understanding of the role of the various parties.

Central Government

In 2005, responsiblities for the development of a national biosecurity system were allocated to Biosecurity NZ, a new department within the Ministry of Agriculture and Forestry. This includes developing improved systems for border controls, surveillance, incursion response, biosecurity science and management of high-risk pests.

Regional Councils

Regional councils (and unitary authorities such as Tasman District Council) are responsible for management of pests in their region through the development and implementation of a Regional Pest Management Strategy.


Different industries, such as the NZ Forest Owners Association, have developed their own biosecurity systems that focus on the early detection of pests.


Landowners are responsible for managing pests that are listed in the Regional Pest Management Strategies, on the land that they own.
