On Sunday 5th October 1902, St. Columba's Church, although still without chancel, vestry, or porch, was dedicated for use. The church, built in wood, was to be completed according to the plan drawn up by Mr. Burnside, architect of Dunedin, on the land given to the parish by the Faulks family. St. Columba's Church building has been the centre of the life of Anglican Christian worship in Wanaka from 1902 to the present.

When the Presbyterian congregation decided to erect a new church their old St. Andrew's building was available for purchase. Mrs. Joy Smith put forward the suggestion that St. Andrew's be purchased and joined to St. Columba's to give the space needed for larger congregations at Christmas, Easter, weddings and funerals, and to supply a lounge for meetings and social events. There would also be space for kitchen and toilet facilities. This proposal was accepted and acted upon. St Andrew's was duly transported and added to St Columba's so that two of the earliest buildings in the Wanaka area are now preserved, early roots of the community's spiritual and social heritage. Bishop Peter Mann dedicated the extensions on Saturday 21st January 1989. Services continue to be held here.
