A police spokeswoman told the Rotorua Daily Post Tarawera High School's police studies course starting was unrelated to the shooting and had been arranged before the incident.
In collaboration with New Zealand Police and Unitec, students can gain 29 NCEA credits from the Introduction to Police Studies course for Year 12 and 13 students.
It aims to prepare the students to apply for entry to the Royal New Zealand Police College (RNZPC) on completion.
Acting Senior Sergeant Shane Tailby, area response manager for Whakatāne police, said policing was a fantastic career.
"Students who completed this course would be on a pathway to becoming an officer on leaving school."
Rotorua Girls' and Boys' High School's were the first in the country to trial the course, and Boys' High deputy principal Hamish Lockwood said it was a beneficial course regardless of the student's future plans.
