The Immigration Service is cancelling the visa of an American businessman Jim Peron because he contributed to a publication deemed objectionable by the chief censor.
The department has started the process of permanently cancelling Peron's business visa. He has 21 days to respond.
In March this year, the American was the subject of a number of allegations from Winston Peters, who claimed Peron was promoting the cause of sexual relations between men and boys.
Peters told parliament that in the 1980s Peron was the editor and a contributor to San Francisco magazine Unbound - which advocated sexual relations between adult men and young boys.
Peters passed a copy of the publication to the chief censor who in May classified it as objectionable. This prompted the Immigration Service to investigate the case again.
The service said the censor's decision has put Peron's good character in jeopardy.
