Northern United Rugby Football Club Inc was established in 1989 as a result of the amalgamation of the Porirua and Titahi Bay Rugby Football Clubs.
Northern United RFC is known as ‘Norths’ within the Wellington Rugby Football Union. The initial playing strip was the Porirua Rugby Club jersey with the Titahi Bay Rugby Club shorts and socks. But in 1990 the official blue and white playing strip was introduced, which remains prominent 22 years on.
