Mr. Eze, a controversial businessman, with interest in oil and gas, is a close ally of President Goodluck Jonathan.
He has been linked to several lucrative contracts awarded by the outgoing Jonathan administration.
Mr. Eze has also made several questionable donations, including N1.8 billion in 2013 for a church building and a youth centre in Otuoke, Bayelsa state, the hometown of President Jonathan.
Speaking shortly after seeing the president-elect, Mr. Eze said he was glad that Mr. Buhari, seen as one of the most disciplined leaders in Nigeria and Africa, has been elected president.
