Jerry Collins' manager says he has had two meetings with the former All Black at a prison cell in the Japanese city of Hamamatsu.
Collins, who was arrested 11 days ago for carrying two knives in a department store, has said he was armed because he was terrified of a Brazilian gang and feared for his safety.
He has remained in custody since then and his manager, Wellington-based lawyer Tim Castle, has flown to Japan to be with him.
Mr Castle said today he had two meetings with Collins today and had met his lawyer.
"I have also had constructive discussions with the Japan authorities, which will continue after this short break. In all meetings I have been accompanied by the New Zealand embassy consul whose support has been both crucial and professional.
