Rosehill College in the south Auckland suburb of Papakura was placed in lockdown earlier on Thursday following a school fight.

Police confirmed to Newshub they were called to the school after reports of several students fighting at 2:09pm.

An anonymous student told Newshub police were called to the school because students' parents were fighting students on their children's behalf.

The lockdown has now lifted, and students have been told they can return to class.

The source, who wants to remain anonymous, told Newshub there have been "multiple fights" at the school recently, and said it's an unsafe place.
