According to police and school statements reported by 1News, the incident prompted a full campus evacuation and a controlled explosion at a neighboring park, with no injuries reported.
The emergency response began at approximately 8:55 a.m. on Wednesday at the Takapūwāhia campus. According to 1News, the New Zealand Defence Force’s Explosive Ordnance Disposal Team deployed to the school to handle the materials, eventually moving the substances to an adjacent park to conduct a controlled explosion and render them safe.
Following the operation, authorities lifted cordons surrounding the school. The administration implemented a phased release plan for the student body. Year 9 students were held in the school hall to await in-person pickup by parents and caregivers, requiring explicit confirmation before departure. Students in Years 10 through 13 were released immediately to travel home independently, while students in Te Whare Ako made individual travel arrangements through direct parental contact.
