Manzongo began his ministry at Church of St. Mary Magdalene, Harare, and then was rector of St. Joseph's,
Dzivarasekwa. Manzongo relocated to
Wisconsin in 2015 to complete a degree at
Nashotah House. During this time, he was a supply priest for the
Episcopal Diocese of Eau Claire. He returned briefly to Harare to serve as rector of St. Paul's Church before migrating to Canada to accept the post of incumbent at St. Luke's Anglican Church in
Dryden, Ontario. In 2024, Manzongo became incumbent of the 140-year-old Holy Trinity Anglican Church in
downtown Winnipeg. At the time, the historic church was physically deteriorating and at risk of
structural collapse. In April 2025, Holy Trinity and the diocese signed a memorandum with the downtown development agency and an architectural firm to support the church's restoration, beginning with a rehabilitation study that focuses on designing a new foundation for the troubled structure. In May 2025, Manzongo was elected bishop of Rupert's Land. ==Personal life==
