“Greenpeace is concerned that an oil company with an exploration licence off Northland may be bribing iwi leaders to bolster support for their controversial drilling plans. Greenpeace has taken a picture of three executives from Norwegian oil giant Statoil meeting with an Iwi leader at a Wellington cafe. 

Campaigner Mike Smith said it goes against the Norwegian government's protocols specifying that consultation must be done through appropriate procedures and representative institutions. He said it's an effort to win over individual iwi leaders rather than engaging collectively. "They've got clear instructions from the Norwegian government that they should only deal with institutions and mandated representatives, that's our main concern."
