On January 2, 2019, the Vatican announced that Pope Francis appointed Rex Andrew C. Alarcon as the new bishop of the diocese.

[2] On September 1, 1974, the Diocese of Daet was formally established along with the installation of its first bishop, Celestino Rojo Enverga, a native of Jose Panganiban, Camarines Norte.

Since the Augustinian missionaries Diego de Espinar and Francisco Merino had established Christian communities in Paracale in 1571, it took 393 years for Camarines Norte, the land of gold and pineapple, to be erected as a diocese.

According to Bishop Celestino Enverga, two years after the canonical erection in 1974, there was a diocesan house complex, a charity clinic, and a haven for homeless people discharged from hospitals.

The first decade was characterized by construction of structures: the first phase of the diocesan house was completed in 1977 and the Holy Trinity Cathedral was ready for its dedication by September 1, 1984.

Elena; the Parish of the Most Holy Trinity was established in 1991, the vision-mission statement of the diocese was formulated in 1991; the Holy Trinity Preparatory Seminary, the first seminary in the diocese, was opened in 1992, the first Diocesan Pastoral Assembly was held in 1992; the Bishop Enverga and the Carillon Halls were inaugurated in 1993; and the Second General Pastoral Assembly was convened in 1994.

Archbishop Rex Andrew C. Alarcon, the current apostolic administrator of the diocese is the Archbishop-elect of the Archdiocese of Caceres after Pope Francis appointed him on February 24, 2024.
