The Wurlitzer organ is one of the main attractions of the theatre. To give it its proper name, the Hope-Jones Unit Orchestra, Style 260 Special, Opus was built in 1929 and is one of only 13 made.

It was originally installed in the Civic Theatre in Auckland to provide musical accompaniment to silent films. It is vastly different from today's electronic organs. The console, with its three keyboards and multitude of stops, tabs and pedals, is only part of the organ. On either side of the theatre are large chambers housing 1100 pipes and numerous percussion instruments which are played from the console.

The air to drive the organ comes from a big fan compressor in the basement, which pumps out 1500 cubic feet of air per minute. The organ is not limited to producing music and can create the sounds of horses hooves, thunder, wind, a car horn, fire gong, steamboat whistle and even the roar of surf.

The six hectares of park-like grounds surrounding the complex are an additional attraction for visitors. The car park is flanked by gardens, shrubs and lawns, while at the rear of the complex are picnic areas and a man-made lake.

A bush walk skirts the lake, passing through a stand of native bush where many birds such as wood pigeons, fantails, tuis, and sometimes the long tailed cuckoo, can be seen. The lake itself is a favourite haunt for blue herons and various breeds of ducks. The large grassed areas surrounding the complex are often used for various activities such as parachuting and club outings. The actual site of the complex is also of historical interest, for it was close to here in 1886 that the official opening of the Wellington–Manawatu Railway took place. A memorial tablet near the main gates commemorates the occasion.

The grounds and surrounding areas are can be booked for wedding ceremonies, club picnics, car rally pit-stops and other functions.
