 The communion table, pulpit and font in the Sanctuary were given in 1931.

The reredos (screen) dates from 1963.

The sanctuary window was made by J Wippel & Co of Exeter and installed in 1964 in memory of the women of Knox. The central figure is Christ in Glory surrounded by the winged symbols (man, lion, ox & eagle) of the 4 evangelists: Matthew, Mark, Luke & John. Kneeling are Peter (crossed keys) and Paul (sword). The dove above Christ's head represents the Holy Spirit. The emerald rainbow and Greek letters alpha & omega, at the top of the window, come from the Book of Revelation.

The Stuart memorial at the rear of the church was made by R H Fraser of Dunedin in 1896. The top depicts the transfigured Christ, the blessing of the children and Christ's agony in Gethsemane. Further down are the evangelists above their winged symbols. The main figures are John Knox, the 16th century Scottish reformer for whom Knox Church is named, St. Andrew (Patron Saint of Scotland) St. Margaret (11th Century Queen of Scotland) and Dr. Donald Stuart, the first minister of Knox Church 1860 - 1894.

Two windows on each side above the organ pipes were given in 1966.

The archangel Michael and an RNZAF pilot feature in a memorial window to FO Robert Weir Herron who died on active service in 1944.

The organ here now was installed in 1931, with its pipes in the central front archway and the console detached at the front of the church. In 1963, the organ pipes were split and the console moved to under the left-hand balcony.
