A 15-year-old girl has been arrested following an assault in Kaikohe that was filmed and posted online.

Police have asked everyone who had shared the video online to delete it as a way of taking a stand against violence in the community.

The assault happened at the bus depot on the corner of Mangakahia Road and Broadway, Kaikohe about 3.30pm on Tuesday.

Senior Sergeant Brian Swann said the victim suffered injuries to her face and head in the prolonged assault was witnessed by a large crowd of bystanders before a member of the public has intervened.

"The victim and her family are understandably very upset and shaken by this vicious unprovoked assault."

Mr Swann said it was of great concern to police that a video of the assault has been posted online and widely circulated.

The sharing of this video indicates an acceptance of this type of thuggish behaviour and a glorification of the offender, he said.

The victim suffered further harm in the sharing of the video, he said.

"Kaikohe Police would like to thank the members of the public who came to the aid of the victim of the assault, however are concerned that so many stood by and watched the attack take place," Mr Swann said.

"This type of attack has no place in civil society."

The offender has been charged with assault and will appear in the Kaikohe Youth Court today.

Police are also investigating the roles of persons who encouraged and aided the offender with a view to laying further charges.
