David Bain has been spotted relaxing in Dunedin, weeks before a book on his retrial is to be released and he makes his speaking debut at an international conference.
The former Dunedin man was convicted in 1995 of murdering his parents, two sisters and brother and spent 13 years in jail before being acquitted in a 2009 retrial.
Friends of David Bain group head Catherine Spencer told the Otago Daily Times: "He is in town. He is just here visiting friends and that is all I am going to say."
She confirmed she was one of the friends he had visited.
Mr Bain was seen swimming at St Clair Hot Salt Water Pool with a female acquaintance, and later relaxed at an outside table.
