Our ambition is that New Zealand is protected from invasive biological threats. Our native biodiversity and our ability to derive income both from primary industries and from our unique landscapes are constantly threatened by invasive weeds, pests, and diseases.

Our work enables New Zealand to:

  • better respond to biosecurity threats
  • reduce pest, weed and disease impacts
  • kia tiakina nga taonga tuku iho (better protect treasured species)

Manaaki Whenua collaborates with many partners as part of our drive to help New Zealand reach its Biosecurity 2025 and Predator Free 2050 goals. Our research focuses on border security for early detection and prevention, and improving control methods for established invasive species.
