Principals uncertain about their right to discipline international students have asked the Ministry of Education for clarity.
Principal of Rotorua's John Paul College, Patrick Walsh, also a spokesman for the Secondary Principals' Association, said schools had taken a view they had responsibility for international students 24/7.
But a recent High Court decision against Tauranga Boys' High School appeared to contradict that, Mr Walsh said, and concerned principals hoped to meet with ministry officials this month.
"Up until this point our understanding was the code of practice required us to be responsible for the international students 24/7, and added to that, we have obligations under health and safety law."
The code of practice for institutions teaching international students, including schools, was updated for the first time in 14 years this month.
