generally built to lighter standards than main-line vehicles. It was not uncommon for road vehicles to be adapted, either as haulage power or rolling stock. As road vehicles became more suited for these operations the bush trams gradually faded away and none are now operating. A prominent example of a bush tramway was the Taupo Totara Timber Company's line between Putaruru and Mokai, and an example of a mineral tramway was the Dun Mountain Railway. Other bush and mineral tramways included - North Island South Island Street tramways Major street tramway networks were constructed in Auckland, Wellington, Christchurch and Dunedin, with smaller operations in Gisborne, Napier, New Plymouth, Wanganui, Nelson and Invercargill. Employing horse, steam or electric power, they operated in most cases until the 1950s when improved buses saw most of the tracks scrapped. Urban tram operations, built from scratch as tourist attractions, have more recently been restarted in Christchurch (1995) Auckland (2011), and Wanganui (2013). See Trams in New Zealand. Heritage and Private railways A large number of societies operate working heritage railway lines and museums. Most of these are run largely or wholly by volunteer labour, except commercially operated private trust owned Dunedin Railways in Dunedin, which employs paid staff.
