The Defence Force has cleared five instructors of inappropriate relationships with recruits at Waiouru Military Camp.
Investigations into four other non-commissioned officers are continuing.
Earlier this year, seven staff at The Army Depot training establishment at Waiouru Military Camp were removed following allegations of inappropriate behaviour.
Investigations were then also started into two others no longer working at the training centre.
Another officer, accused of assaulting a recruit, was cleared by a military tribunal.
At the time, Major General Peter Kelly told Morning Report two members of the leadership team were also replaced after he "lost confidence" in them - a strong message, he said, as it was a first in his 34 years in the service.
