Police are investigating an assault in New Lynn amid a series of youth violence incidents around the transport hub in recent weeks.
A witness told RNZ she saw a group of teenage girls attacking another girl on Tuesday.
Last Friday, schools warned students to avoid the New Lynn bus station over fears of a planned mass brawl between students.
Auckland Transport said it had deployed a security officer at the New Lynn station from 4.30pm to late night every day.
Police said they would continue to patrol the area before and after the school day.
