Anti-mining protesters are accusing a security firm of sending an undercover worker in to spy on them ahead of the Minerals Forum in Dunedin last month.
Members of the Stop the Minerals Forum Coalition say this and other experiences have made them suspect they were under surveillance in the lead up to the meeting of mining and interests, which was held at the Dunedin Centre and Town Hall on May 28.
RNZ reporter Emma Hatton has the story.
