Today Assistant Commissioner Bill Searle confirmed that police were investigating the actions of a number of police officers following concerns around their alleged behaviour while off-duty.
Police would not confirm if the investigation and the alleged sexual assault were linked.
"The allegations relate to inappropriate behaviour that occurred over the course of the evening of 4 February and the early hours of 5 February 2019, while the officers were deployed outside their district," Searle said.
"The New Zealand Police's code of conduct applies at all times, regardless of whether staff are on or off-duty.
"Police treat any allegations relating to potential misconduct by police officers seriously."
The Searle said the actions of the individuals were currently being reviewed and employment investigations are underway.
"One of the officers involved has currently been stood down, while inquiries are ongoing," he said.
"We are unable to comment further at this time due to the ongoing employment investigation."
