The suburb is named after the Wairau Creek, which flows through the suburb. The name Wairau in Māori means "Waters Gathered by a Net".^[4]

The Wairau Valley was primarily swampland and farmland in the early 20th century, including some areas that were leased to Chinese market gardeners.^[5] In 1959, the Auckland Harbour Bridge opened, leading to rapid suburbanisation on the North Shore.^[6] The Wairau Valley developed stormwater runoff problems as the surrounding greenspaces were developed, and the Waitemata County Council began plans to line the Wairau Valley waterways with concrete.^[7]

From 1970, Wairau Valley was redeveloped as an industrial area,^[7] and only a few years later became the largest industrial area on the North Shore.^[6]

In 1982, The Warehouse opened their first store in New Zealand in Wairau Valley.^[6] In 1992, the North Shore Sports and Leisure Centre was opened in the suburb (now known as the Eventfinda Stadium).^[8]
