hunters and fishermen. Also non-agricultural Sami people built huts to help them manage reindeer. The earliest huts were only allowed to be used by people from the communities that owned them. Outsiders were not allowed to use the resources of other communities' erämaas. Huts that were free for everyone were first seen in late 18th century Finland, when dwelling places were built along walking routes for passers-by. In the 19th century the authorities started building these huts. Later in the 20th century they started to be built for travellers. New Zealand New Zealand has a network of approximately 950 backcountry huts. The huts are officially maintained by the Department of Conservation (DOC), although some of the huts have been adopted and maintained by local hiking and hunting clubs by arrangement. There are also unofficial and privately owned huts in some places. They vary from small bivouac shelters made of wood to large modern huts that can sleep up to 40 people, with separate cooking areas, utilities and gas. Some huts were initially commissioned or built by clubs along commonly walked routes, both for safety reasons as appropriate, and sometimes for convenience. The network of back-country huts in New Zealand was largely extended in the mid-20th-century, when many more were built to serve the deer cullers of the New Zealand Forest Service. Most larger and more modern huts, like some found on the Great Walks, have been purpose designed and built to serve trampers. Many of New Zealand's back-country huts are remote and rarely visited, and it is common for recreational trampers to design trips with the idea of reaching and visiting specific huts. Some people actively keep count of which huts they have visited, a practice which is informally referred to as hut bagging. Back-country huts in New Zealand were free to use until the early 1990s, when the New Zealand Department of Conservation began charging for their use. For most back-country huts, nightly hut tickets are purchased via an honesty system by people who use the huts, with an additional option of purchasing an annual pass for people who use huts frequently. Huts on frequently used and heavily marketed tracks, such as the New Zealand Great Walks, usually operate on a booking system, and often have resident wardens checking the bookings of users who arrive to stay the night. Since the inception of hut fees in New Zealand, there
