The Hokianga Sawmill Company wharf was built in 1878 at Kohukohu as the first stage of the company's sawmilling operations there. It was constructed by Auckland shipwright William Lowe from totara and heart kauri with local Maori engaged to do the labour. The sawmill was later taken over in 1888 by the Kauri Timber Company as part of its nationwide purchasing of sawmilling companies and assets. The wharf and mill site was later used for the manufacture of butter boxes from 1933 until 1937. The wharf was decommissioned in 1938. The former wharf is on the Heritage New Zealand list of historic places as a Category 2 site, List No: 3947 and was registered on 6 September 1984.[1]
