Moana is a small town in the West Coast Region of the South Island of New Zealand. It is situated on the northern shore of Lake Brunner, and is beside the outflow of the lake into the Arnold River. There is a pedestrian suspension bridge crossing the Arnold from the town to access the lake shore across the river, with some short easy bush walks on each side.

The town has a permanent population of less than 100, but is a popular location for summer tourism. There are around 300 holiday homes and a camping ground.

The town's main tourist attractions are the panoramic views and water sport opportunities arising from its position on the shores of Lake Brunner. The Midland Line railway passes through Moana; the TranzAlpine tourist passenger train passes through once in each direction daily, and freight trains of coal operate more frequently.

In May 2013, Moana became one of the first places in New Zealand to get 4G wireless broadband.

Moana is described by Statistics New Zealand as a rural settlement and covers 1.16 km (0.45 sq mi). It had an estimated population of 80 as of June 2024, with a population density of 69 people per km. Moana is part of the larger Lake Brunner statistical area.

In 1886, the New Zealand Midland Railway Company entered a contract with the Government for the construction of 376 kilometres (234 mi) of railway between Christchurch and Nelson via Brunnerton (later Brunner) over a ten year period. The line was to be built and operated by private enterprise. In November 1892, the company opened the railway from Brunnerton, but at that stage Moana was only a flag station. By March 1894, the railway had reached Jacksons. However, in 1895 the company collapsed. In May 1895 the Government seized the company's assets on the grounds that the contract had expired with the works incomplete. The Government eventually completed the works under the Railways Construction and Land Act 1881.

The opening of the railway to Moana enabled settlement by Pākeha and establishment of timber mills in the local area. By June 1895 a 140 metres (460 ft) siding was being operated at Moana station by the Lake Brunner Sawmill Company. The date of construction of the original Moana railway station building is not known, but by 1895 the station had a 61 metres (200 ft) long platform and 240 metres (790 ft) siding.

On 16 April 1926, the station building was destroyed in a fire. A replacement building was constructed in the same year. The replacement was to the standard type A design, from the family of standard railway station designs prepared by Railways architect George Troup.

The Moana Railway Station is listed as a Category 1 Historic Place by Heritage New Zealand. It is the only type A station building still remaining that is complete with its associated sidings and goods sheds. Heritage New Zealand has also given a Category 1 listing to the Moana Railway Station Historic Area comprising the station building, a footbridge, the goods shed and the former station master’s house (now used as a cafe).
