The Northern Club purchased the building in 1869, the club having been formed earlier in the year. Gentlemen's clubs developed in nineteenth-century Britain, enabling social and business networks to be maintained. Early members of the club included the future Prime Minister, Julius Vogel (1835-1899), and prominent businessmen, such as Thomas Russell (1830-1904) and David Nathan (1816-1886). Governors of the colony were among those invited as guests, reinforcing the exclusivity of the organisation. The club refurbished the interior, and in the process reinforced social divisions through the building's layout. Service rooms for employees were located in the basement and members' reception rooms on the ground floor, while personal servants were not allowed in the upper chambers, although exceptions were made for governors. Expansion to the facilities generally occurred during periods of economic boom. A new dining room and fifteen bedrooms were constructed at the rear of the building in 1883-1884, and accommodation for residential staff was added in the 1920s. Exclusively male in its membership for over 120 years, facilities for women were introduced only gradually. The first female member was admitted in 1990, shortly after the earliest woman after-dinner speaker, the Minister of Finance Ruth Richardson, who addressed the club in 1989.
The Northern Club Building is significant as the oldest surviving gentlemen's club in Auckland, and one of the city's earliest major surviving structures of 'commercial Italianate' design. It has strong links to early colonial institutions, such as the provincial government and British army, as well as prominent individuals in New Zealand history. It is representative of important aspects of colonial society, such as all-male associations and business networks. It demonstrates the implanting and nurturing of traditions introduced from Britain, particularly among the social elite. The building's well-preserved interiors yield information about nineteenth- and twentieth-century life in New Zealand, from the use of decor to attitudes about gender and class. The building is particularly significant for its association with other early colonial structures in the area, such as the Albert Barracks Wall and former Government House. It is the earliest building in the historic Princes Street streetscape, with significant landmark qualities that include its distinctive cover of Virginia Creeper, planted in 1927.
