Baber said police are now assessing this information and will be making follow-up inquiries on any relevant matters.
"Police recognise that it can be difficult for victims to come forward. We respect the courage of those who have contacted us."
"We continue to encourage anyone who may have information that can assist our investigation to come forward."
When contacted for comment, a Dilworth School spokeswoman said she was not aware of today's arrest.
Yesterday, police announced six men, who are all in their 60s and 70s, had been charged in relation to alleged sexual offending.
The men appeared in the Auckland District Court and were granted name suppression.
They are expected to appear again in the same court in early October.
When the news broke yesterday, school management held a press conference to publicly address the situation.
Headmaster Dan Reddiex, who was appointed last year, said that "naturally as a father, educator and human being" he found the allegations "appalling" and "deeply saddening".
"I cannot comprehend the trauma or pain those who suffered abuse must have endured," Reddiex said.
"And for this hurt we are truly sorry. And so I want to be absolutely clear, the Dilworth School I know and lead today has zero tolerance for abuse of any kind.
"The health, safety and wellbeing of our students is our single greatest priority and responsibility.
"We know that a safe environment is instrumental to our students flourishing both personally and academically."
Dilworth Trust Board Chair Aaron Snodgrass said the school had taken a leadership role in improving processes around alleged abuse at the same time the Royal Commission of Inquiry into Abuse in Care was established in New Zealand in 2018.
Last year, Snodgrass wrote to all Old Boys and parents apologising for historical abuse and he said he also outlined what was being done to provide a safer school environment.
"We established a confidential, free Listening Service for Old Boys if they want to discuss their experiences with an independent clinical psychologist."
The Board had actively sought to have any suppression of Dilworth School's name waived in connection with the court proceedings because they wanted to be able to openly discuss their response with the school community, he said.
