United Future leader Peter Dunne says the decision by forest management company Timberlands to charge people for access to the Kaiangaroa forest south of Rotorua is unacceptable.
From 1 May, those wanting to access the forest to hunt, fish, or shoot game birds, will have to register with a security firm and pay $50 for a permit.
Mr Dunne says that goes against the well-established common right of New Zealanders, to fish and hunt without charge.
He says Timberlands' decision is an abuse of power.
Mr Dunne says there has been a long standing access issue between Timberlands and anglers who want to fish the Rangitaiki river which needs to be resolved.
