NZ Expands Wasp Control Programme With $2 Million Funding Boost

Conservation Minister Tama Potaka announced the funding boost through the International Visitor Conservation and Tourism Levy (IVL), allowing the Department of Conservation’s Wasp Wipeout programme to operate nationwide for the first time.

New Zealand will significantly expand its fight against invasive wasps after the government committed an additional $2 million to extend control efforts across visitor destinations and important biodiversity areas. Conservation Minister Tama Potaka announced the funding boost through the International Visitor Conservation and Tourism Levy (IVL), allowing the Department of Conservation's Wasp Wipeout programme to operate nationwide for the first time.

Wasp Control Set to Reach Every Region

The extra funding will enable Wasp Wipeout to expand into all regions of New Zealand, supporting community groups with bait, technical guidance and pest control expertise to reduce populations of introduced German and common wasps.

Potaka said the insects are not only an annoyance for people enjoying outdoor recreation but also pose a serious threat to native wildlife and ecosystems. He noted that invasive wasps are among New Zealand's most destructive insect pests, causing economic losses estimated at more than $130 million each year.

The programme has already delivered strong results in areas where it currently operates, with support from local organisations including NZ Deerstalkers branches, Fish and Game groups, tramping clubs, mountain biking organisations and the Te Araroa Trails Trust.

Coverage to Double Across Key Landscapes

At present, Wasp Wipeout treats around 30,000 hectares annually, mainly across South Island beech forests in Nelson-Tasman, Marlborough, the West Coast and Canterbury. With the new investment, the programme aims to double its coverage to 60,000 hectares.

The expansion is expected to improve protection for native species while also creating a more enjoyable experience for visitors exploring beaches, campgrounds, walking tracks and forest areas. Potaka said introduced wasps are a widespread issue across the country, making community involvement an important part of long-term control efforts.

Funding Supports Research and New Control Tools

Part of the funding will be used to strengthen planning and coordination of wasp management projects while supporting the development of new technologies and research aimed at improving pest control methods. New Zealand is home to some of the highest densities of Vespula wasps anywhere in the world. During peak summer months, heavily infested areas can become dominated by the constant sound of wasps competing with native wildlife for food resources.

The government says expanding Wasp Wipeout will help reduce those impacts, protect biodiversity and restore healthier natural environments where native birds can thrive. The nationwide expansion marks one of the largest recent investments in wasp control and is expected to strengthen efforts to protect both New Zealand's ecosystems and its outdoor visitor experiences.
