An $80,000 war against weeds is about to begin in Abel Tasman National Park.
The government has made the money available to knock back banana passionfruit vines and old man's beard across 23 properties in Tata and Ligar Bays.
The funding adds to an existing project, known as Project De Vine, which has killed 290,000 vines in Golden Bay since 2010.
The project is a collaboration between the private landowners, iwi, community, councils and a private trust.
Conservation Minister Eugenie Sage said Project De Vines' goal was ambitious, but achievable.
Pest plants knew no boundaries between private and public land and smothered New Zealand's native plants, preventing native seed generation, she said.
Wasps have also been a target of pest eradication programmes in Abel Tasman
