Established at the confluence of the Clutha / Mata-Au and Kawarau Rivers after gold was discovered nearby during the Otago Gold Rush of the 1860s, Cromwell's location saw it become a junction for travel between Dunedin and areas further inland, such as Wānaka and Queenstown. As gold mining declined, the town developed to service farms and orchards in the surrounding area, becoming known for stone fruit and as part of the Central Otago wine region. The town remains a hub for people travelling throughout the region, with State Highway 8B running through the town and acting as a main route for travellers to Queenstown.
