She said the school would advise parents and caregivers on the next steps as soon as health teams provided that advice.
"In the meantime, the school remains open, but we support your choice to keep your child at home until we receive more clarity of the situation from the Ministry of Health and Ministry of Education."
The school runs primary classes from years 1 to 8 and has 505 students on its roll, according to the Education Review Office.
"Please be assured that we are, have been and will continue to adhere to our published mitigation plan, that we shared with you and we have a number of health measures in place," Matthys-Morris said.
The Delta variant has been increasingly popping up in schools as the virus has been increasingly infecting more people in Auckland and across the country.
Earlier this week, Te Papapa Primary School in Onehunga reported having an infectious child at the school between November 22 and 25.
Marina View School in West Harbour also had a child test positive for Covid-19, who was infectious while attending the school between November 24 and 26.
Covid-19 Response Minister Chris Hipkins yesterday said he expected children aged 5-11 would be able to start getting vaccinated against the virus from next month, subject to the approval of Medsafe.
Primary and intermediate schools earlier reopened during level 3 on November 17.
They have had restrictions like staggering class times, keeping kids from mingling, and having students in Years 4 and above wear masks to lower the risk of Covid spreading.
Matthys-Morris said the Ministry of Health advised parents and staff to watch for symptoms and if any develop to get that person tested immediately and then stay home.
Those who do not have any Covid-19 symptoms can still come to school, she said.
She also urged any eligible unvaccinated whānau to get their vaccination as soon as possible.
