There are currently 39 registered clubs incorporated and secondary schools affiliated with the Northland Rugby Union, most of which have teams at both senior and junior levels.
Northland Rugby Union was known as North Auckland Rugby Union following the amalgamation of Whangārei, Northern Wairoa, Bay of Islands, and Otamatea initially and then followed by Mangonui, Kaipara, Hokianga, Whangaroa, and Rodney in 1925. Rugby union was first played in Northland in late 1880, and the first union was set up in the province in 1895, known as the Marsden Football Union.[34] In 1994, North Auckland changed its name to the Northland Rugby Football Union. They played their first ever match as a union on 3 August 1920, in an 11-0 victory over South Island Country. However, they did not play their first inter-union match until 27 July 1922, an 8-6 loss to Auckland. Their first inter-union win came in August 1923, when they beat King Country[35]
The Auckland Rugby Union and Northland Rugby Union became regular rivals. They had Ranfurly Shield victories over them in 1960 and 1971. Northland won the Ranfurly Shield on two further occasions. 1950, when they defeated South Canterbury and 1978, when they defeated Manawatu. In the 1971 challenge Northland won 17-12 in a narrow match played in front of 47,000 people at Eden Park, Auckland. The following season 40,000 spectators packed Whangārei Okara Park to watch the rematch. With the city's population only 34,000, this showcased the significance of both the shield and the rivalry with Auckland. However they lost 15-16.[35]
The reputation of Northland rugby took a downfall following its controversial victory over Manawatu in 1978. After what seemed to be an excessive amount of stoppage time, Northland kicked a winning penalty. What followed was the refusal that the union wouldn’t put the shield on the line for its final home matches of the season against Southland and Otago. However no rules were broken.[35]
Professional era
Northland began their professional era playing in the inaugural Air New Zealand Cup competition. They are known as the Taniwha, a reference to the mascot adopted in the professional era. Along with Auckland and North Harbour, Northland is part of the BluesSuper Rugby franchise.[35]
