Tuhoe says the Government's decision to change the law to safeguard secretly filmed evidence is political interference.
A new law is to be passed to ensure evidence gathered through covert cameras can still stand in court.
It follows the revelation that charges against most of the people arrested after the 2007 police raids were dropped because the police gathered evidence illegally, by trespassing on Tuhoe land.
A Tuhoe leader, Tamati Kruger, says politicians should leave the judiciary to do its job and not interfere.
"We've been led to believe that the politics of the situation will be removed and be quite a large step away as due diligence carries on through the courts, but now we seem to have a collaboration of the Crown and the courts."
