 The filming of parts of "Lord of the Rings" in Tongariro National Park caused enough disturbance to some areas of the park, including one known locally as "Orc Road", that contractors had to be hired to restore the areas later.In December 2005, a contractor won an award from the Department of Conservation for their restoration work.Each film had the benefit of a full year of post-production time before its respective December release, often finishing in October or November, with the crew immediately going to work on the next film.
