There was some dispute over where to commence a railway to the settlement of Orawia. One of the two main proposals was to extend the Tuatapere line, and the other was to build a branch from Waikouro on the Wairio Branch. Ultimately, the Tuatapere proposal was accepted, and although construction was postponed due to World War I

Operation

The line was run as two separate branches from Tuatapere: the Tuatapere Branch from Invercargill, and the Orawia Branch. During the days of steam motive power, most services on the branches were operated from a depot at Tuatapere. Trains were typically mixed, carrying both passengers and freight. One such train daily operated from Tuatapere to Invercargill and return, while another ran Invercargill to Tuatapere and return. Orawia was served by a service from Tuatapere on Mondays, Wednesdays and Fridays. Along the line, a lucrative logging industry was established and many bush tramways were built to provide easy cartage of logs to the railway line. A timber mill was established in Tuatapere to process the logs and it provided much traffic for the railway. In the early days of the line, oil shale

 valley and its settlements.

Passenger services on the Orawia Branch did not last even a decade. By 1932, passengers were no longer carried and goods trains ran only twice weekly. Passengers could travel on the rest of the line until the early 1950s, and around this time the daily Invercargill to Tuatapere and return goods train was withdrawn. This was partially offset by a Monday to Friday goods train from the Wairio Branch junction at Thornbury to Tuatapere. The Orawia Branch looked as if it could be closed at any time until a cement works was constructed in the town in 1956. It provided sufficient traffic to justify the Orawia Branch's existence.

Traffic declined during the 1960s, and when steam motive power was replaced by DJ class

 diesel-electrics in June 1968, Tuatapere locomotive depot closed and services changed to operate out of Invercargill thrice weekly, on Monday, Wednesday and Friday. In May 1968 the cement works in Orawia closed, and deprived of its main source of traffic, the Orawia Branch closed on 1 October 1970. By the mid-1970s, only 4,500 tonnes of traffic yearly were railed west of Riverton and the line was cut back to Riverton on 30 July 1976. There were expectations that forestry developments would create sufficient traffic from Riverton, but these failed to eventuate and the line from Thornbury was closed on 15 January 1978. The short section from Makarewa and Thornbury became part of the Wairio Branch.

The branch today

Some notable relics remained after closure. The most significant of these was the causeway and truss bridge

. The Orawia Branch's formation is distinct for much of its length, and at the terminus is the goods shed, with the ruins of the old cement works nearby. The formation of the Tuatapere Branch is also pretty clear in most places, and in Wakatapu some discarded rails and sleepers are at the old yard site, while a loading bank is at Ruahine and relocated station buildings still stand at Longwood and Orepuki.
