Pond said the cost of repairs had “now reached into the thousands of dollars” and the funds should be going towards students’ learning, wellbeing and opportunities.
Police had been involved on numerous occasions, along with other school staff, she said.
“Many of the young people have been spoken to and a number have been formally trespassed.
“Despite this, the behaviour has continued, which is why we feel it is important to speak openly now.
“To our wider community – if you see any suspicious behaviour on or around our school grounds, please contact police immediately.”
A police spokesperson said police were investigating recent reports of trespass at a school in Jones St, Whanganui East.
“Anyone with information that may help our inquiries can contact police via 105 either online or over the phone, referencing file number 260113/8307.
“Alternatively, information can be provided anonymously on 0800 555111 or at Crime Stoppers New Zealand.”
Pond said the school was “incredibly proud of our kura and the young women who learn here”.
“We ask for your support in helping us keep Whanganui Girls’ College safe, respected and cared for.”
