A Lower Hutt police officer has been charged with assault after allegedly using his baton to protect himself from attackers, The New Zealand Herald has reported.
The incident, before Christmas, was believed to have happened when the officer attended an incident alone and was set upon by a group at the scene.
Extensive suppression orders mean the officer cannot be identified, but police spokesman Nick Bohm confirmed the assault charge had been laid.
''When it is necessary to use force, constables must, according to the law, use only reasonable force,'' Bohm told the Herald.
''This includes force that is necessary and proportionate, given all the circumstances known at the time."
Police would also conduct their own investigation.
The officer will appear in court again later this year.
