The building was registered by the New Zealand Historic Places Trust (since renamed to Heritage New Zealand) on 25 November 1982 as a Category II historic place. Outside the front door on the Cambridge Terrace frontage, two further heritage items are registered as Category II: a gas light, and a hitching post. The gas light was installed for public lighting in circa 1900, but the gas lighting system was switched off in 1918 when municipal electricity had become available. Somehow, this particular gas lamp was never removed, and it was restored for the February 1963 royal visit by Queen Elizabeth II. Years later, the lamp was shifted a short distance to be located outside of the club's main entrance. The lamp was still run on gas for many years after the gasworks closed in 1985, but in the 1990s, the Canterbury Club converted it to an electric light. In 1999, the Christchurch City Council and the Canterbury Club reinstated gas supply to the lamp. Adjacent to the gas light is a hitching post, erected in the 1870s or 1880s by the club for members to tether their horses. Once common throughout colonial towns, there are very few remaining today.
