Farm pests

AgPest™ is a free tool to assist New Zealand farmers and agricultural professionals in decision-making regarding weed and pest identification, biology, impact and management.

Freshwater pests

The establishment of alien pest species in New Zealand's freshwater systems continues to threaten the values and utility of our natural resources. Early identification of new pest incursions and appropriate action can help prevent further spread or mitigate their impacts.

Identify it

Each animal, insect and microorganism leaves clues behind as to who they are. Although it can be difficult to figure which pest is affecting you, here are some options for you to try out.

Kauri dieback

Phytophthora agathidicida, the pathogen that causes kauri dieback, was only discovered in 2009, and formally named in 2015 (previously it was known as Phytophthora taxon Agathis). The pathogen can sense a kauri tree’s roots, and swim towards them using a tail-like flagella.

Marine pests

Marine pests are species that have been introduced to New Zealand waters by human activities and have the potential to cause significant impacts to the country’s marine environments and resources.
