He moved to England, where he studied at the Trinity College, in Bristol, until 1968. He was finally ordained a Deacon at June 26, 1968, in Buye. Rev. Ndayisenga was a teacher at the Theological College in Buye for the following years.
He was Bishop of the Diocese of Buye since 1979. He was consecrated the second Primate of the Episcopal Church of Burundi in 1998, holding office until his retirement on July 17, 2005. He was succeeded by the Most Rev. Bernard Ntahoturi.
