<P> In Peter Jackson 's film adaptation of The Lord of the Rings , Orodruin was represented by two active volcanoes in New Zealand : Mount Ngauruhoe and Mount Ruapehu . In long shots , the mountain is either a large model or a CGI effect , or a combination . The production was not permitted to film the summit of Ngauruhoe because the Māori hold it to be sacred , but some scenes on the slopes of Mount Doom were filmed on the slopes of Ruapehu . </P>
