Police are investigating complaint after a Young Nats event in Auckland.
The alleged incident occurred after Young Nats Christmas drinks at the Brew on Quay bar last Tuesday; an event two National MPs were said to be attending.
It is alleged a woman, aged 17, and some friends went to the young man's apartment after the event.
The woman was not a Young Nat member and was a guest at the event, according to Newsroom.
The woman was allegedly taken to a room at the man's apartment, where he tried to grab her face and kiss her, while keeping her away from her friends.
After leaving the room and the apartment, it is alleged she was pursued across the road and into a fast food outlet's toilets by the man, who allegedly continued to grope her.
