The New Zealand F class was the first important class of steam locomotive built to operate on New Zealand's railway network after the national gauge of 3 ft 6 in (1,067 mm) was adopted. The first locomotives built for the new gauge railways were two E class double Fairlies for the Dunedin and Port Chalmers Railway. The F class was the first class ordered by the Central government, and between 1872 and 1888, a total of eighty-eight members of the class were constructed.
The F class was a tank locomotive with a wheel arrangement of 0-6-0. They operated essentially everywhere on New Zealand's railway network doing a variety of jobs. F class locomotives could haul light passenger trains at speeds up to 70 km/h (43 mph) or pull up to 800 tonnes of freight on flat trackage. Originally the design was meant for use on the Southland Railways, and three prototypes were built by Neilsons of Glasgow in 1872; among these was what would become F 13, now preserved at the Ferrymead Railway in Christchurch.
The engines were originally given names from the works of Sir Walter Scott by order of a Government official. Originally some had New Zealand names; for example F 36 (later F 13) was originally named Clutha, and later renamed Edie Ochiltree. Some were at times classified as the O class as these had Cartazzi axles, but by the nationwide renumbering of 1890 all were classified F. By this time none of the engines carried names any more.
