Welcome from the Cardinal βA community of faith rooted in the islands of Tonga since the first Marist missionaries arrived in 1842.
The Catholic Church's presence in Tonga began in 1842 with the arrival of Marist missionaries led by Bishop Pierre Bataillon, S.M., appointed as the first Vicar Apostolic of Central Oceania. From these early beginnings, the faith took root among the Tongan people, growing steadily despite the challenges of a predominantly Methodist society.
The Church adapted to the unique culture of Tonga β a kingdom with deep traditions of faith, family (famili), and community. Catholic missionaries built schools, hospitals, and parishes that became cornerstones of Tongan life.
Marist Bishop Pierre Bataillon establishes the first Catholic mission in Tonga as part of the broader Pacific vicariate.
A dedicated vicariate for Tonga is created, recognising the growing Catholic community across the island groups.
The vicariate is expanded to include Niue, reflecting the Church's broader Pacific mission.

The Malia Tupu 'ImΔkulata (Cathedral of the Immaculate Conception) stands on Vuna Road in Nuku'alofa. Also known as the Cathedral of St. Mary, it is the mother church of the diocese and seat of Cardinal Mafi. The diocese also has the Minor Basilica of St. Anthony of Padua in Nuku'alofa.
The Diocese of Tonga is immediately exempt to the Holy See β not belonging to any ecclesiastical province β reflecting its unique position in the universal Church. Our mission is guided by priorities of evangelisation, service to the poor, family life, and youth formation, always rooted in Tongan culture and identity.
As an island nation on the frontlines of climate change, the Diocese is a strong voice for environmental justice and the dignity of Pacific peoples β concerns championed by Cardinal Mafi on the world stage.

Cardinal MafiAnniversary"My dear brothers and sisters in Christ,
Welcome to the website of the Catholic Diocese of Tonga. I am grateful that you have found your way here, whether you are a member of our faithful community across the islands, a visitor to our beautiful kingdom, or someone seeking to know more about the Catholic Church in the Pacific.
Our Diocese is small in numbers but rich in faith, culture, and love. From the cathedral in Nuku'alofa to our most remote parish in the Niuas, every community is precious in the eyes of God. We are a people called to deepen our faith β ke loloto e tui β and to share that faith with generous and open hearts.
As your bishop, I carry you always in my prayers. I invite you to join us in prayer, in service, and in the joyful proclamation of the Good News across these islands we love.
May God bless you and your families.
+ Soane Cardinal Mafi
Bishop of Tonga
Soane Patita Paini Mafi was born on 19 December 1961 in Nuku'alofa, the capital of the Kingdom of Tonga. He comes from a deeply Catholic family β both his father and grandfather served the Church as catechists, a legacy of faith that has clearly shaped his vocation.
Growing up in the Kolofo'ou area of Nuku'alofa, the young Soane was active in his local parish youth group. He studied for the priesthood at the Pacific Regional Seminary in Suva, Fiji, and was ordained a priest on 29 June 1991 by Bishop Patelisio Punou-Ki-Hihifo Finau, S.M., at the age of 29.
His early priestly ministry took him to the Ha'apai island group, where he served in parish work for four years β giving him a deep understanding of life in Tonga's outlying communities.
In 1995, Bishop Foliaki appointed the young Father Mafi as Vicar-General of the Diocese, a remarkable appointment for a priest of only five years' standing. He subsequently pursued postgraduate studies in religious education at Loyola University, Baltimore, Maryland, graduating in 2000, then spent six years in Suva training local priests for the Pacific region.
In June 2007 he was appointed Coadjutor Bishop of Tonga and consecrated on 4 October 2007. He succeeded to the See on 18 April 2008 β the first diocesan priest to serve as Bishop of Tonga; his three predecessors were all Marists.
On 4 January 2015, Pope Francis announced Bishop Mafi's elevation to the College of Cardinals. The historic ceremony took place on 14 February 2015, with Cardinal Mafi given the titular church of Santa Paola Romana in Rome. At the time he was the youngest member of the College of Cardinals.
Cardinal Mafi served as President of the Episcopal Conference of the Pacific (CEPAC) from 2010 to 2016. In April 2025, he participated as a cardinal elector in the conclave that elected Pope Leo XIV.
Cardinal Mafi has become one of the most prominent voices for Pacific peoples and climate justice. As a low-lying island nation, Tonga faces existential threat from rising sea levels. Cardinal Mafi uses his position in the College of Cardinals to advocate urgently for action, linking Catholic social teaching with the concrete suffering of Pacific communities.
He has also spoken out against the negative impacts of globalisation on Tongan traditional culture, calling for a development model that respects the dignity, identity, and way of life of Pacific peoples.
