The Dannevirke after which the town was named is an extensive Viking Age fortification line in Denmark which had a strong emotive symbolic role for 19th-century Danes, especially after the site had fallen into German hands in the German-Danish War of 1864 - a recent and very painful event for these settlers. The settlement quickly earned the nickname of "sleeper town", as the town's purpose was to provide totara sleepers for the Napier - Wellington railway line. At one stage the area had 50 operating sawmills. After the native bush was cleared, the land was turned into pasture for grazing animals.
