The protesters at Parliament are being given a choice - leave by your own volition or leave by force. 

Police from around the country have descended on the area for a pre-planned operation. 

Newstalk ZB's Jack Crossland says he can see more than a hundred police officers, and they mean business. 

Newstalk ZB's Nick James says protesters are retreating, reluctantly. 

“Police have essentially pushed protesters all the way back past St. Paul’s cathedral here, it remains a pretty tense situation.”
