over responsibility for the harbour and the provision of facilities, the wharves at Port Chalmers were managed by the Railways Department until 1928. Construction of a long graving dock was commenced by the Otago Dock Trust in July 1868. The commissioning of the graving dock in March 1872 (which had cost £56,069 2s 11d) and the increasing size of ships resulted in reduced demand for the floating dock which was finally beached at Carey’s Bay. The remains of the dock are still visible as late as the 1940s. Owing to the need to accommodate increasingly larger vessels a new graving dock was constructed by the Otago Dock Trust between 1905 and 1909 at a cost of £74,475. It was long which allowed it to take vessels up to in length. Once the dock was completed the Otago Dock Trust merged with the Otago Harbour Board on 21 May 1910. In April 1928 the long Norwegian whaling ship, C.A. Larsen became the largest vessel serviced by the graving dock up until that time. Following its taking over operation of the wharves from the Railway Department the Otago Harbour Board moved its headquarters to Port Chalmers in 1929. The first all-container ship to visit New Zealand was the Columbus New Zealand, which berthed at Beach Street Wharf on 26 June 1971, before the container terminal had been built. It used its own on-board crane whose arm folded out to land or pick up containers from the wharf. The redevelopment lead to the closing in 1975 and filling in of the graving dock while the wharves were replaced by two berths – the later multi-purpose berth is to the right – and a heavy-duty paved space for storing, washing and devanning (unpacking) containers. In 1988 the Otago Harbour Board was replaced by a quasi-autonomous local government entity, Port Otago Ltd. The port currently has three berths suitable for handling containerized, multi-purpose, and conventional vessels; Beach St, the container berth and the multi-purpose three berths. The swinging basin is dredged to , with a turning diameter of . A $23 million long extension to the existing multi-purpose berth which increased its total length to was completed in 2019. Quarrying A quarry known as the “Big Quarry” was opened on Church Street in March 1866 and operated until it closed in the 1920. This supplied Port Chalmers brecia locally known as bluestone which was used
