The area that became Warkworth had limited Māori occupation. The
Mahurangi River was the route between the
Mahurangi and
Kaipara Harbours for the local tribes. This route was later used by Europeans. The purchase was not finalised until 1853 and land was not subdivided nor resold until then, instead the Crown offered timber licences to settlers. The town developed slowly, primarily around the Mahurangi River wharf, where settlers could supply goods and services for the
Auckland market. Bridge House Lodge, established on the site of John Anderson Brown's home next door to the Warkworth Bridge, is the oldest surviving building in Warkworth. The Mahurangi Post Office and Library were established in 1859. Some of the 3rd Marine Division servicemen were stationed in Warkworth. The
Warkworth Town Hall was used to stage entertainment for the servicemen. By 1944 when the United States Army had left, the
New Zealand Army requisitioned many of the camps. By 2010, the facility had been redeveloped as an
