A New Zealand journalist has been detained for several hours on Nauru after interviewing an Iranian refugee.

Barbara Dreaver, from TVNZ, was in Nauru to attend the Pacific Islands Forum but has now been stripped of her media accreditation.

Dreaver had been told by Nauru media officials she was permitted to talk to refugees as long as she didn’t go into a camp to do so and received the refugee’s permission.

Dreaver had started interviewing a refugee outside a restaurant when several police officers showed up and asked her to come to the police station.
