Two hero cops who stopped the accused Christchurch mosque gunman can now be identified.

The pair who apprehended the alleged gunman were Senior Constable Jim Manning and Senior Constable Scott Carmody of Canterbury. Name suppression for the officers lapsed today.

They managed to ram his vehicle to a halt and arrested the suspect on March 15.

"From our perspective we were doing our job and I know our colleagues would have done the same thing in that situation," Manning and Carmody said in a statement.

"Our actions are reflective of who we are as Police officers and as Kiwis.

"Every day when we go to work the safety of the community is our priority and that was our focus when we made that arrest on 15 March."

Police Commissioner Mike Bush said the officers' actions spoke volumes to who they are as people and as police officers.

"They put their lives at risk to stop the alleged gunman and stop further harm," he said.

"The events of 15 March were truly tragic and something we as a country have never seen before and I would hope never see again."
