David Bain has left New Zealand and will spend the rest of the year in Europe.
Mr Bain was acquitted in June of the murder of his family in Dunedin on 20 June 1994 after a three-month retrial in the High Court in Christchurch.
One of Mr Bain's key supporters, Joe Karam, says he received his passport the week after the verdicts. He left on Saturday to stay with friends in Britain.
He says Mr Bain, 37, is now instantly recognisable wherever he goes in New Zealand and is seeking some "time out."
Mr Bain served 12 years in prison before the Privy Council quashed his convictions in 2007. A new trial was subsequently ordered.
Cases for compensation from the Crown for wrongful conviction and to recover Mr Bain's share of the family estate are being prepared, but Mr Karam says he does not know when they will be lodged.
