Here’s an article that gives additional info to how Peter Jackson must act when he commences filming in protected land areas (and what is planned in those areas):
DOC Land Rings to Film Trilogy
The Press On-Line – November 12, 1999
Orcs, horses, and helicopters will start swarming over
Department of Conservation locations deep in the South
Island’s most spectacular areas as The Lord of the Rings
filming gathers pace.
The Conservation Department has permitted filming in
protected areas, but has imposed 77 conditions in a 40-page
document, and slapped on a $50,000 bond. During the next
two months, action sequences in the $360 million trilogy will be
filmed in the Mount Owen area near Murchison, the Wakatipu
basin near Queenstown, around Te Anau, and in Fiordland.
Filming will be based around the hobbits as they trudge across
the Middle World on their mission.
But film company Three Foot Six’s access is restricted. It has
to maintain public access to the areas and drive only on the
roads. It will also pay for a DOC officer to monitor how well it
protects the environment.
Publicity officer Clair Raskind said 400 people would be in the
shoot starting next week around Queenstown.
Up to 300 horses and riders would be auditioned for one
scene, she said.
“We’re doing all the action and the most dramatic scenes.”
However, the set will stay under wraps for now.
Lord of the Rings producer Tim Sanders said it was a relief the
application had been approved.
“Some of New Zealand’s most beautiful places will be
showcased internationally through this film trilogy,” he said.
