Police have received over 70 phone calls from the public as the investigation into alleged historical abuse at Auckland's Dilworth School continues.
Seven people have been arrested and charged on a number of serious offences, including sexual violation, attempted sexual violation, indecency and indecent assault. All the arrests are men aged in their 60s and 70s.
Detective Senior Sergeant Geoff Baber said since the arrests were made in mid-September, police have fielded a "significant number" of phone calls and emails.
"The Operation Beverly [Dilworth School investigation] team have received well over 70 phone calls from members of the public," he said.
"We are continuing to assess any information provided and investigators are currently making a number of enquiries into the additional information received to date."
He added police have increased the number of staff working on the investigation, including bringing a counsellor on board.
"Having an experienced counsellor available will allow them to work with victims through the process as this matter continues," he said.
No further arrests have been made.
"Police recognise there is a continued public interest in this investigation and we continue to acknowledge the courage of those who have contacted us," Baber said.
"We continue to encourage anyone with information or that may wish to discuss matters with police to come forward."
The investigation team can be reached by calling 09 302 6624 or emailing Operation.Beverly@police.govt.nz.
The Dilworth Trust Board said earlier in September they were saddened that some of their old students suffered abuse during their time at the school.
"We apologise to any old boys who have been affected by abuse of any kind at our school," chairperson Aaron Snodgrass said in a statement.
"The Board considers all forms of abuse, including physical, emotional and sexual abuse unacceptable."
Snodgrass said none of the men charged continue to have any connection to Dilworth School.
"The Board has full confidence in all of Dilworth School's current employees."
He said the school had made the decision to "proactively address" the historic abuse and has implemented several policies and programmes to "enhance the safety for our current students".
