Our Parish began in 1851 with the arrival of two French Marist Missionaries, Father John Stephen Pezant SM and Fr Lamplia. They established a small chapel and residence in Taupo Quay Wanganui.
Fr Lamplia set to work to evangelise the people of the river and set up several mission stations.
Fr Pezant concentrated on the settlers of Wanganui and the Catholic soldiers of the 57th Regiment, the Rutland Regiment who were based at the Rutland Stockade, the site of the present day cenotaph and War memorial and the 65th Regiment, the York Regiment on the site of the present day Cooks Gardens.
Their parish area was large and first extended from the Rangitikei area south of Wanganui to New Plymouth in Taranaki to the north. In 1853 a block of land was granted to the Catholic Church in Victoria Avenue. This land, next to the present Majestic Square, was the site of the St Mary's Church until 1973.
The present church which opened in 1976 occupies land purchased in the late 1890's and houses the font, stained glass windows, statues, vessels, the organ and a part of the altar rails from the 1877 church. Some wood from the old church has been reshaped into the Stations of the Cross.
