If you grew up in Christchurch before the city’s gasworks was decommissioned in 1982, you'll almost certainly remember the grimy industrial building that dominated the scene next to the Waltham Street overbridge. It was maybe the most industrialised site in the city, where dirty columns of smoke bellowed out from chimney stacks signalling coal being fired to create gas for residents and businesses. It was a subject that captivated painter Doris Lusk. She had previously painted the Dunedin Gasworks in around 1935, and also turned her hand to painting many other industrialised sites – hydroelectric stations, Christchurch’s Pumphouse, sluice mines at St Bathans, the wharf at Onekaka, and numerous roads and railways slicing their way through the green countryside.
