Livingstone thanked the community for their support and cooperation throughout the investigation.
"We'd like to acknowledge the public for the information we received, which contributed and assisted our team of detectives piecing together the events of that morning.
"I would also like to acknowledge the dedication of the investigation team, who have worked tirelessly to achieve this result."
This investigation spanned several Police districts and involved a large number of staff members.
"From the initial attending uniform staff to the various investigators, both from Taupō and other stations across the district, I cannot speak more highly of their dedication, professionalism and tenacity to get to this point and hold those involved to account."
Police were unable to provide further information at this time as the matter is before the courts.
