The Government has declared Friday 26 June 2026 a special public holiday to mark the 200th bicentennial anniversary of the establishment of Christianity in the Kingdom, the Prime Minister’s Office has announced. The decision was approved by His Majesty’s Cabinet under Section 2(b) of the Public Holidays Act.

The commemorative day reflects what officials described as a significant milestone in Tonga’s history, recognising the enduring role of Christianity in shaping national identity, values and cultural heritage.

The Free Wesleyan Church of Tonga has also released its programme for the 102nd annual church conference, scheduled from 23 June to 2 July, with 26 June dedicated to the anniversary celebrations.

Meanwhile, academic and church-led research initiatives are underway to document the history of Christianity in Tonga. A committee chaired by Queen Nanasipauʻu, including senior church leaders and scholars, is overseeing a planned six-volume publication project.

Historical accounts highlight early missionary efforts from 1826 as a turning point in the sustained establishment of Christianity in the Kingdom, which went on to influence education, governance and national unity.

Further events are expected across Tonga and the diaspora leading up to the commemorations, with churches, schools and communities preparing programmes to mark the bicentennial year. The observance is expected to draw widespread participation across denominations.

Further details of national commemorations is expected in due course.
