Despite the decline Hokitika retained a harbourmaster until the 1920s and remained an official port until the 1950s. As with many other customhouses throughout New Zealand Hokitika's was rebuilt during the 1890s, as part of the Liberal government's building programme initiated by Premier and West Coast politician Richard Seddon (1845-1906). The Hokitika Customhouse was designed by John Campbell (1857-1942), then a draughtsman in the Public Works Department. Campbell was eventually appointed to be Government Architect in 1909. Erected for £400, the Customhouse was a small single-storey building clad in weatherboard with a gabled porch over the entrance.
In design the customhouse is one of Campbell's standardised government buildings, which were typified by a rectangular plan, a hipped roof with a gabled porch over the entrance, the use of vertical and horizontal battens to subdivide the walls, and shingles above the windows. The latter reflects Campbell's interest in the American Stick and Shingle style. Other similar buildings include the former customhouse in Napier (1895) and the courthouse at Hunterville (1895), both of which are also registered by the New Zealand Historic Places Trust Pouhere Taonga.
After the harbourmaster was removed from Hokitika the customhouse was taken over by the Ministry of Works and used as a depot. It was threatened with demolition during the 1980s but was eventually preserved and moved onto a site across the road by the river. A lean-to addition at the rear of the building was removed and the interior returned to its original layout of three rooms. However, the public counter and one fireplace was removed during this work. A trust was established to look after the building and it has been used by community groups over the years.
The Customhouse at Hokitika is one of the last remaining links to Hokitika's heyday as a busy and prosperous port. The establishment of Hokitika as a port-of-entry with a customs officer was a direct result of the West Coast gold rush, and the customhouse stands as a physical link to the history of extractive industries on the West Coast. The building is one of Campbell's earlier designs and part of an attempt by the government to standardise public buildings for ease and quickness of construction. As Campbell preferred to design and build in brick, the customhouse at Hokitika is an interesting example of his timber buildings, which formed a very small part of his work. Today the Customhouse stands as a prominent landmark close to its original site.
