Police are investigating allegations a teenage concert-goer was indecently assaulted by a group of men at a sold-out dance party.
The young woman has complained to police after she was allegedly manhandled by fellow revellers.
The woman was reportedly groped after her top was pulled down.
The alleged incident happened during the Our:House dance party at Mt Smart Stadium in Auckland on Friday, as electronic music group Major Lazer took the stage.
Today a police spokeswoman confirmed a complaint was made to the Manukau police station yesterday.
"We are investigating an alleged indecent assault on a female at Mt Smart Stadium."
Officers in Auckland would look into the matter, the spokeswoman said.
Last night Major Lazer were playing in Sydney, Australia.
