Passage: Principal photography for all three films was conducted concurrently in many locations within New Zealand's conservation areas and national parks. Filming took place between 11 October 1999 and 22 December 2000, a period of 438 days. Pick-up shoots were conducted annually from 2001 to 2004. The series was shot at over 150 different locations, with seven different units shooting, as well as soundstages around Wellington and Queenstown. Along with Jackson directing the whole production, other unit directors included John Mahaffie, Geoff Murphy, Fran Walsh, Barrie M. Osborne, Rick Porras, and any other assistant director, producer, or writer available. Jackson monitored these units with live satellite feeds, and with the added pressure of constant script re-writes and the multiple units interpreting his envisioned result, he only got around four hours of sleep a night. Due to the remoteness of some of the locations, the crew would also bring survival kits in case helicopters could not reach the location to bring them home in time. The New Zealand Department of Conservation was criticised for approving the filming within national parks without adequate consideration of the adverse environmental effects and without public notification. The adverse effects of filming battle scenes in Tongariro National Park meant that the park later required restoration work.
