Green MP Keith Locke, has used his valedictory speech to Parliament to call for less power for the police and the state.
Elected in 1999, Mr Locke will retire at the November election.
He said he's been most active trying to advocate peaceful solutions, including opposing the war in Afghanistan.
Mr Locke told the House what's saddened him most is Parliament's willingness to increase police and state agency powers through legislation.
He said New Zealand now had anti-terrorism laws it did not need and the country's prisons were overflowing.
"I appeal to Parliament to try to find the brake pedal or even, gasp, the reverse gear."
