An investigation is under way into an alleged assault by police officers at a station in Auckland.
The incident is said to have happened earlier this year in the holding cells at the Henderson station and is understood to have involved three officers including a sergeant.
It is understood the matter was referred to the Independent Police Conduct Authority by Police National Headquarters.
The authority has confirmed that its chairman, Justice Lowell Goddard, an investigator and a legal analyst, inspected the station on the 18 March. Senior officers were also interviewed.
The IPCA says it is looking into conditions and the treatment of detainees and considering whether any misconduct or neglect of duty occurred. It expects to finalise its terms of reference for the inquiry soon.
