"An internal employment investigation is underway into comments made by a recruit at the Royal New Zealand Police College.
"New Zealand Police has the same privacy obligations as any other employer and as such is not in a position to provide any further detail at this time."
The Herald has previously revealed police recruits have been stood down because of alleged links to organised crime, but this investigation comes shortly after the culture and training at Police College was put through an independent review commissioned by Deputy Commissioner Tania Kura.
The report is not publicly available but Kura recently told Stuff the review found areas to improve including the academic framework, the type of staff employed as trainers, and its connection to "real world" policing.
A new director of training at Police College was appointed in February, the highly rated Superintendent Warwick Morehu, and a second review into the entire training process is now underway.
