Wasps are NZ's ultimate villain - wreaking havoc on our environment, killing native birds, young bats, insects, lizards and honey bees.


Wasp Wipeout is a community-led conservation project aimed at significantly reducing German and common wasp populations in the worst affected areas of New Zealand this summer.

Alongside our partners (Stuff, the Department of Conservation (DOC), and Conservation Volunteers NZ), The Tasman Environmental Trust helps mobilise the community to donate and volunteer towards significantly reducing invasive wasp populations throughout New Zealand including Canterbury and the West Coast, Nelson, Tasman and the Marlborough Sounds, Central Otago, Wellington/Kapiti, Auckland and Manawatu.

All donations go to the Tasman Environment Trust, which will distribute the funds to purchase bait and bait stations to continue and expand wasp control operations.


Wasp Wipeout began as a pilot project in the Nelson region in 2016, supported by the Nelson Mail and Stuff as well as the Department of Conservation, local conservation groups, businesses, scientists and members of the community. Since then the programme has expanded to include other areas that have high infestations of wasps.

The Common and German Wasp:

Wasps are New Zealand’s ultimate villain towards humans and nature alike. The species we’re focusing on (German and common) were introduced. They wreak havoc on our environment, killing native birds, young bats, insects, lizards and honey bees. Wasps also feed off honeydew, a valuable food source for native fauna and honey bees. Wasps cost the NZ economy more than $130 million a year.

They also attack, injure, and have been known to kill humans. The biomass (total weight of wasps in Nelson and Tasman) exceeds all other pests in New Zealand, including possums, stoats and rats. There are a million hectares of beech forest in the South Island and over 5, and up to 40, wasp nests per hectare.

About us

TET connects people with conservation by offering expertise in protection & restoration of natural environments.​ We work collaboratively with the community including special interest groups, landowners and businesses in Tasman and Nelson.

Use of funds

The Tasman Environment Trust will distribute funds to support volunteer logistics, purchase bait and bait stations for wasp control operations in targeted areas across New Zealand.

Any unspent funds will be carried over to 2022/23 wasp programme.

Wasps compete with our native species, especially birds. We're very grateful to the volunteers working to reduce the wasp numbers.

I despise paper wasps in particular. Those creatures are monstrous and I'm happy to help cut their population back.

As someone who loves hiking in our beautiful region and was stung so badly by a swarm this summer that I am now allergic ( and have nearly needed to activate my PLB twice from stings) I am so glad and so grateful that you are doing this. THANK YOU I wish i could give more!
