The Foreign Affairs Minister Charlie Flanagan is due to meet with Pat Hickey's family this afternoon.
Mr Hickey was released from Bangu Prison yesterday.
As a condition of his release authorities remain in possession of his passport to prevent him leaving Brazil.
The Olympic Council of Ireland President says there is "no substantive proof of any wrongdoing on his part".
Minister Flanagan said his priority is Mr Hickey's safety as an Irish citizen abroad.
Mr Flanagan said: "Like any other Irish citizen, the matter of his welfare and his wealth is one of fundamental importance to me as Minister for Foreign Affairs.
"One of my fundamental duties is the protection of the welfare of Irish citizens abroad."
