Waikato Police have arrested a former St Peter's School teacher following an investigation into historical sexual offending at the Cambridge school.
Police said a 73-year-old is charged with 10 counts of indecent assault involving seven victims and will appear in the Hamilton District Court on Wednesday.
The investigation focused on the period from 1974 to 1980, with St Peter's School management aware and supportive of the investigation.
Police urged anyone with information to come forward.
"Police would like anyone with information to contact them on 105 quoting file number 211203/3311 or by emailing Operation.Caster@police.govt.nz."
St Peter's confirmed in a statement they're cooperating with police investigations into the former staff member.
The school apologised in November last year for historical staff abuses, which led to alumni coming forward and speaking to police.
"We fully support alumni who have come forward. The School Trust Board wants to assure them we have been cooperating fully with NZ Police and we will continue to do so," School Trust Board chair John Macaskill-Smith said.
"To avoid compromising the judicial process in any way, St Peters' Cambridge will minimise further public statements about the charges laid today."
The school said it had initiated many safeguards to protect current and future students who learn and board with the school.
They said they have developed a child protection policy and processes and invested in ongoing child safeguarding training for staff while also ensuring students have a range of ways to report any concerns.
"Child abuse prevention and safeguarding is openly discussed with students to reinforce that abuse in any form is not tolerated at St Peter's Cambridge," Macaskill-Smith said.
