South Taranaki District Council says criticism by the Waitangi Tribunal of local government's role in petroleum development may affect resource management beyond oil and gas.
A tribunal inquiry has found local authorities unwilling or unable to protect Maori interests.
It says councils are not fulfilling the Crown's Treaty obligations and waahi tapu (sacred sites) are being destroyed.
The district council says the findings are fair and could benefit resource management generally, not just decision-making on petroleum.
More on this can be heard on Insight on Sunday.
