Report a pest plant, pest animal or plant disease

Pest plants, pest animals or plant diseases

We implement pest management programmes for specific types of pests.

See the list of pests we control in the Regional Pest Management Strategy (RPMS).

If you want to report a pest plant (weed), pest animal or plant disease not in the RPMS, email our Biosecurity team or phone us on 09 301 0101.

When to contact Ministry for Primary Industries (MPI)

For some pests, you may also need to notify the Ministry for Primary Industries (MPI) on 0800 80 99 66. You can also visit the MPI website to see if the pest is known to be in New Zealand.

MPI is responsible for managing exotic pests when they enter our country.

From time to time, MPI will identify threats from new pest species. When there is a threat, they will lead a national response to prevent the new pest from establishing.

Examples of exotic pests

• Queensland Fruit Fly
• Red vented bulbul - brown or black bird with a white abdomen and a red patch beneath its tail. It causes damage to crops, and attacks and displaces other birds due to its competitive nature.

Marine pests

If you think you’ve seen a marine pest outside its known location, note the location and take a photo or sample if you can.

Report it to:

• MPI on 0800 80 99 66.
• us by emailing our Biosecurity team or calling 09 301 0101.

Examples of marine pests

• Asian paddle crab - off-white to chestnut brown with flattened swimming paddles. An aggressive predator, it can carry diseases to other crabs, lobsters, shrimp and prawn.
• Australian droplet tunicate - white tubes found in sand, seagrass beds, wharves and harbours. They displace fish species, smother beaches and pollute marine structures.
• Clubbed tunicate/leathery seasquirt - woody stalks with brown leathery skin. They are found in aquaculture structures and boat hulls. They prey on larvae of commercially important fish species.
• Mediterranean fanworm - spiral crown that project from a leathery flexible tube. They attach to hard surfaces in soft sediments. They prey on larvae of fish species.
• Pyura - brown mat with a hard, sac-like body that has sand and shell fragments. They are visible at low tide. They displace native species, including greenshell mussels.
• Undaria - brown or yellowish plants that can grow up to 3m tall. They thrive in polluted waters and form colonies that displace fish species.
