Police have described the actions of a "small number" of the 90,000 people who attended Auckland's Polyfest as "disappointing" after officers responded to two fights outside the festival.
Video of a young female dragging another by the hair before laying punches into her is the latest shocking footage to emerge following the event last week.
However, police say they did not make any arrests over this incident, but they are following up on the videos.
They said only two arrests were made during Polyfest, and they weren't related to the event.
In one video posted to Facebook yesterday morning, a young teenager dressed in a white t-shirt and blue jeans is seen yanking another young female by the hair.
She then starts laying punches into the teen she's gripping on to.
A group of onlookers then move in to break up the conflict. Two males try to hold back another girl, who tries to have another go at fighting.
The violence between the young women reportedly took place behind a tent at the event.
As of today, the video has been watched more than 176,000 times.
1 NEWS NOW has contacted SMC Events, which organises ASB Polyfest, for comment.
Separate video uploaded to Facebook on Saturday shows a group of young males in a street fight that apparently took place outside the Manukau Sports Bowl.
In the video, a group of males can be seen fighting, with two of them being kicked several times.
A police spokesperson told 1 NEWS yesterday they attended the fight just before 4pm on Te Irirangi Drive on Saturday.
No arrests were made, police said, as the people pictured were "long gone" by the time they got there.
That video has so far been watched 360,000 times.
"It is incredibly disappointing to see the videos being posted online which reflects the behaviour of just a small number of the 90,000 people who attended," said Tracy Phillips of Counties Manukua Police.
"Polyfest is a great family event and chance to celebrate the diversity across Auckland and New Zealand."
