By 1974, technical problems caused a rebuild. Since then, the original Large Open Diapason has been reinstated and a Tuba stop added.

The Organ console now on the left has 3 manuals with pedals and 53 speaking stops.

Plaques on the Organ Console commemorate former organists, and these two, donations in 1931 and 2000 and organ rebuilding and extension in 1974 and 2000-1.

On the front choir pews, the Coat of Arms of the Royal School of Music is on the left and the emblem of the Presbyterian Church of New Zealand is on the right.

The roof is a fine hammer-beam roof. Hammer-beams sit horizontally on top of the walls and project inwards, supporting the curved rafters (or braces) that spring upward to the top of the roof.

The hammer-beams are painted blue and white. The white carved 'flowers' are a type of decoration called 'dogtooth moulding'.

Morning view from the gallery.

All our church's stone carving (except the font) is the work of Louis Godfrey, who, worked on Larnach Castle, First Church and St. Joseph's Cathedral also. The capitals (carvings round the tops of the columns) are stylised foliage downstairs. Upstairs, In the Gallery, they are recognisable flowers and foliage and a bird sequence .....

The Compton Miniatura organ was built mid-20th century and installed here in 1993.
