You came for pristine nature – help us keep it that way

You’re here to walk wild places, breathe clean air, and enjoy our excellent local food and beverages along the way.

The insect pest, the brown marmorated stink bug (BMSB), threatens the orchards, vineyards, gardens, and trails that build those experiences. That’s why we’re asking travellers to help keep this pest out of New Zealand.

What’s the risk?

Attacks key crops – the brown marmorated stink bug (BMSB) feeds on more than 300 plant species, including apples, kiwifruit, and grapes — produce that shapes New Zealand’s food and wine culture.

Global impact – overseas the BMSB has caused major crop losses and serious economic damage, particularly in the United States and Europe.

 

 

A nuisance indoors – when populations explode, adults spend the winter inside buildings, creating a significant public nuisance.

Threat to growers – New Zealand’s horticulture sector ranks the BMSB as one of the most serious biosecurity threats. A single incursion could devastate crops, disrupt supply chains, and even jeopardise export markets, leading to lost revenue and global reputation.

Where is BMSB now?

BMSB is native to Asia and has established widely in North America and Europe, with detections in South America (Chile). New Zealand remains free of this pest. Help us keep it that way.

High-risk arrival season!

From September to April, Biosecurity New Zealand ramps up checks at the border and beyond, searching for BMSB hitchhiking with goods and travellers from BMSB-infested countries. We also set traps in risk areas across New Zealand.

Need to know:

· Shield-shaped adult, about 17 mm long; mottled brown with white bands on the antennae and alternating light/dark bands on the outer abdomen.

· Before you travel to New Zealand look out for hitchhiking BMSB. Inspect and clean out your bags, shoes, tents, poles, daypacks, and outdoor equipment.

· When you are in New Zealand, if you think you’ve found one, snap a clear photo and report it immediately to Biosecurity New Zealand by calling 0800 80 99 66 (24/7) or report it online at report.mpi.govt.nz. Early calls make all the difference.
