Woolston became a district in 1882, but before that, it wasn't really a clearly identified place. The mudflats over at Ferrymead, on the eastern side of what is now Woolston, were called "Ohika paruparu" by the Ngāi Tahu iwi, and Māori women gathered shellfish there. That's the only name we know for this area before Europeans settled here.
The western part of Woolston was called Roimata by early Europeans, which means teardrop in Māori. Some land titles in this area still use Roimata as their location, and the name has been revived by groups like the Roimata Community Incorporated Society and Christ Church Roimata, which are active in the area defined by Ensors Road, Brougham Street, Ferry Road, and Richardson Terrace.
One of the first signs of a European community growing here was the Anglican Parish of St John the Evangelist Woolston. The first church, a cob building, was built on the current site in 1857. A new timber church went up in 1882, and then the current concrete church building was built and dedicated in 1960. This parish was officially recognized in 1857, the same year the Anglican Diocese of Christchurch was established, making it one of New Zealand's oldest Anglican parishes.
Before the Lyttelton Rail Tunnel opened in 1867, small ships used wharves along the Ōpāwaho / Heathcote River to service the area. All incoming trade came through Ferrymead and was transported along Ferry Road through Woolston into Christchurch. After the tunnel opened, this area became quite industrialized.
Until early 1870, this place was often called Lower Heathcote. It was a local store owner, Joseph Harry Hopkins, who suggested the name Woolston, after his birthplace in Southampton, England. On June 16, 1870, the name Woolston was officially gazetted. It remained a self-governing borough until November 1921, when it was amalgamated with Christchurch.
The Ōpāwaho / Heathcote River was important for industries here, like wool scouring, which needed a lot of water. By 1966, when the Woolston industrial sewer was built, the river had become quite polluted. Flooding was also a problem, and in 1986, the Woolston Cut was created to bypass a long loop of the river. This 510-meter project cost NZ$2 million and led to trees dying upstream and banks collapsing.
Over the 20th century, Woolston grew into the center of the New Zealand rubber industry. Other industries, like a nugget factory and a gelatine and glue works, also developed here, and many of these businesses are still present in some form. Woolston now hosts Christchurch's largest container terminal. The area has a strong working-class identity because of the factory workers who lived nearby.
Some heritage buildings here were damaged in the 2011 earthquake. The A & T Burt building, which was the former Nugget Boot Polish Factory, built in 1924, was damaged beyond repair and demolished that year. Bloomsbury, a large residential building, and the Jubilee Hospital, established in 1888, are also notable. The hospital closed in 1990, and some of its buildings were demolished, with the remaining ones now housing a fish processing plant.
