Other notable features of the building include stained glass windows dedicated to those fallen in war and to the Otago Mounted Rifles. For many years, the church housed a 1908 Norman & Baird organ, though this was replaced in 1983 by a digital organ by Allen. A full set of eight change-ringing bells, cast by the Whitechapel Bell Foundry, was installed in 1975 and are rung by members of the Australian and New Zealand Association of Bellringers. At that time the only such set in a Presbyterian church outside the United Kingdom and claimed to be the southernmost ring of bells in the world. A large bell on a pedestal stands outside the church, sent from Scotland in 1851. Also located in the grounds in front of the church is a memorial plaque to Dr. Burns. The entrance gates to the church feature two lamps which started life as Edinburgh street lamps, another connection to the homeland of many of the city's first settlers.
