Tāneatua Branch

From 2 September 1928 to 1978 the line was part of the East Coast Main Trunk line from Hamilton. With the opening of the Kaimai tunnel in 1978, the terminus of the East Coast Main Trunk line was changed to Kawerau and the section of line between Hawkens Junction and Tāneatua became the Tāneatua Branch line.

This line across the Rangitaiki Plains follows an inland or southerly route to avoid areas which were swampy at the time of construction, therefore bypassing Whakatāne, the largest town in the area. The intention was for the line to be extended from Tāneatua to Opotiki, then onwards east to connect with the isolated Gisborne Section line from Gisborne.

Some construction work was carried out beyond Tāneatua towards Opotiki in 1928, and an opening ceremony was held for the new line (the ECMT) in Tauranga on 28 March.[1][2][3][4] and on building the Paeroa–Pokeno Line in 1938, when the Minister of Public Works Bob Semple on 28 January turned the first sod ; it was said that the proposed 47 km (29 mi) line would shorten the distance from Auckland to towns on the ECMT by nearly 80 km (50 mi).[5][6][7] [8] However work was stopped in July 1928 when the Government of the day transferred the construction workers to the Rotorua-Taupo line which it had just approved the construction of. However, as late as 1939 £45,000 was provided for extension from Taneatua to Opotiki.[9]

Various routes were investigated and surveyed to link the difficult section between Tāneatua and Moutohora, but all were found to be difficult and expensive. Following the Great Depression, World War 2 and the greater availability of road vehicles in the period after the war, the proposal was subsequently dropped and Tāneatua remained the eastern terminus of the railway line in the Bay of Plenty. Gisborne was subsequently linked to the south with Wellington by way of Napier and Palmerston North with the Palmerston North – Gisborne Line in 1942. The isolated Gisborne Section line became the Moutohora Branch line, which closed in 1959.

The line to Tāneatua was run as the end section of the East Coast Main Trunk from 1928 to 1978. Freight services continued to be operated on the line until 2001.

A passenger service was provided on the line with the Taneatua Express from Auckland between 1928 and 1959. In 1959 railcars replaced this service, but the new railcar services only operated between Auckland and Te Puke, due to negligible passenger traffic between Te Puke and Tāneatua.

The Whakatane Board Mills Line, a private line, was built and operated by the Whakatane Board Mills from Awakeri to their mill in 1939 to serve their large operation. This line was privately operated by the mill until 1999 when the then national rail operator Tranz Rail, took over the operation of the line. Tranz Rail discontinued operating the line in 2001 and the line was closed in 2003, together with the mothballing of the entire Tāneatua Branch line.

In 2015 a rail cart operation, Awakeri Rail Advertures, was established on the section of the line between Awakeri and Rewatu Road.
