New Zealand teachers are finding people who do not attend their schools are joining virtual classes after video links are posted online, NZME understands.
The "Zoom bombing" phenomena in classrooms is being put down to high schoolers "pushing boundaries" during online learning in Auckland, where virtual lessons remain while the region is in alert level 3.
Zoom is a video-conferencing service whose popularity has exploded during the Covid pandemic as workers, students and teachers have stayed home.
Auckland Secondary School Principal Association president Steven Hargreaves was aware of the issue, which often happened after Zoom links appeared on social media platform Reddit.
He thought such behaviour was "entirely predictable".
