One Rotorua police officer has faced criminal charges and 10 have been disciplined internally in the past five years, according to New Zealand Police.
Of those disciplined between 2010 and 2014, four were given warnings, five were disciplined through "professional conversation" and one received performance management.
The figures were disclosed in response to a Rotorua Daily Post Official Information Act request.
Rotorua Area Commander Inspector Bruce Horne said the numbers were few, considering the work officers undertook.
"Given that police officers work in an environment where they are often called upon to intervene in situations involving violence, disorder and people in a highly charged emotional state - the small number of occasions when a police officer has faced disciplinary action over recent years is evidence of the very high standards of professionalism of our staff, their commitment to the organisation's values and clear understanding of the expectations of the communities they serve," he said.
