Police are praising the courage of those who came forward after being drugged and sexually assaulted at a Christchurch bar and restaurant.
Two men have been convicted of dozens charges spanning a period from 2017 to 2018, which include rape, sexual violation, indecent assault and drink-spiking.
The men, whose names are currently suppressed, used a WhatsApp group to discuss their crimes and filmed an explicit video.
Detective Inspector Scott Anderson explained the work that has gone into getting these convictions.
