Port Chalmers Post Office is a Renaissance revival former post office in the town of Port Chalmers. Designed by Colonial Architect William Clayton the Port Chalmers Post Office served the town for over a century before later being converted into a maritime museum. The post office is registered as a category 1 building with Heritage New Zealand.

Situated on reclaimed land at the corner of Beach and George Streets, Port Chalmers Post Office is an L-shaped Renaissance revival two-storey building constructed from local breccia. Quoins are used to decorate the building alongside double-hung sash windows surmounted by an architrave. The building has ornate detailing with modillions, pilasters, cornices, and dentil bands.^[1][2][3] The design of the building is reminiscent of the Dunedin North Post Office, with this being done to emphasise links between the two settlements.^[1]

The interior features rimu and kauri mock panelling and a mezzanine floor.^[4][1]

The building has three plaques: one that commemorates Merchant Navy seamen who died during the Second World War, one acknowledges the role of Port Chalmers in the Second Boer War, and the other by the Waterfront Workers Union.^[5]

The main post office for the wider area was initially established at Otakou in April 1848 but in July it was decided to move the post office to Port Chalmers. The post office was moved into a George Street store in 1860 but in the following year it had moved to a timber building on Beach Street. By 1876 there was a strong desire for a new building as the timber building was located below the road level leading to the smells from the drains impacting the post office — one reporter for the Otago Daily Times referred to the building as 'disgrace to the town'. The government decided to construct a dedicated post office for the town and Colonial Architect William Clayton designed a Renaissance stone building.^[a][1][3]

Construction began in late 1876 with Mr Bauchop being the contractor. When the foundations were being laid water was struck and concrete was used instead. Construction was finished in November 1877. F. G. Downes occupied the upper storey as post master until his death in 1892. Downes' replacement, G. W. Sampson, managed the post office until 1897. Sampson's successor William Bundle remained as post master until his death in 1900.^[1]

In June 1910 a lean-to and scullery was added onto the post office for the postmaster as part of a renovation.^[1]

The Port Chalmers Historical Society took over the building and manage the post office as a maritime museum.^[4]

In 2020 Port Otago purchased the building for $1 in exchange for paying for the management of the maritime museum.^[4] The lean-to, scullery, and balcony; several 20th century outbuildings; a modern building and a modern extension to the post office were demolished as part of the development of a new headquarters for Port Otago.^[1]
