Environmental campaigners say plans for direct action against oil and gas prospectors have been given a boost by the Waitangi Tribunal's findings on the petroleum industry.

It says oil and gas prospecting is on the rise, risking increasing levels of irrevocable harm.

Ngaati Kahungunu territory between Wairarapa and Hawke's Bay is the most intensively explored area outside Taranaki.
The iwi says it wants not to be obstructive but to work alongside companies to protect ancestral and burial sites.
