The NZR A class of 1873 consisted of three types of steam locomotives used on New Zealand's railway network of similar specification but differing detail. The first and most numerous were from the Dübs and Company, the next from the Wellington firm E.W. Mills Lion Foundry, and the last from the Scottish firm of Shanks. The specifications are for the Dubs Yorkshire engines.
