Otira is a small township seven kilometres north of Arthur's Pass in the central South Island of New Zealand. It is on the western approach to the pass, a saddle between the Otira and Bealey Rivers high in the Southern Alps. The population of Otira and its surrounds was 87 in the 2006 Census, an increase of 30 from 2001.
It was originally a stop on the Cobb and Co stagecoach from Canterbury to the West Coast. The railway line was then built from Greymouth to Otira, with the pass navigated by coach, until the railway tunnel opened in 1923. During construction of the tunnel, Otira housed about 600 workers and their families. In the 1950s the town had a population of about 350, but this had dropped to 11 in 1988 and recovered to some extent to 44 in 2010.
The township is principally old Railways housing, much of which was constructed in Hamilton and shipped south to be reassembled on site. As well as the railway station, there is a pub, a fire station, and 18 houses, 14 of them tenanted in 2010.
Otira Viaduct 
Above the town is the Otira Viaduct. Completed in 1999, it spans a 440-metre stretch of unstable land, replacing a narrow, winding, dangerous road that was prone to avalanches, slips and closures.
