On farm biosecurity

On farm biosecurity is a set of measures designed to protect a property from the entry and spread of pests and diseases.  Implementing on farm biosecurity is the responsibility of the landowner and of every person visiting or working on the property. 

Our Biosecurity staff are available to provide advice and resources to farmers looking to improve their on farm biosecurity. Get in touch with them by emailing biosecurity@ecan.govt.nz for more information.

Pathways of spread

Pests and diseases can spread to your property through the movement of people, animals, crops, vehicles, machinery and equipment, as well as in soil mud and contaminated feed and seed. 

Manage your biosecurity risks


  • Ask all visitors to check that their footwear and clothing are free from mud and plant seeds or fragments before entering your farm
  • Provide cleaning facilities such as hand washing basins or foot baths
  • Include biosecurity as part of your farm induction for visitors (as you would with health and safety)

Vehicles, machinery and equipment

  • Limit the number of access points to your farm
  • Place biosecurity signage at the farm entrance (available from Environment Canterbury)
  • Only allow clean vehicles and machinery to access your farm 
  • Provide a washdown area in your yard for vehicles entering or exiting your farm
  • Direct visitors to designated parking areas away from livestock or crops, and if they are accessing the farm ask that they stay on formed roads and tracks whenever possible


  • Before buying new stock, or allowing someone else’s stock to graze on your farm, check whether there are any pests or diseases on the farm they have come from 
  • Isolate new animals in a holding paddock for 21 days
  • Only take healthy livestock to shows, sales and markets

Feed and seed

  • Only buy certified seed and propagation material
  • Before bringing feed on to your property, ask about any pest plants at the source
  • Regularly monitor feed-out areas for pest plants
