Firefighters responded to an alarm on Saturday, and with the gates to the Miramar Hobbit set open, fans seized the opportunity to catch a glimpse of Middle-earth.
While security managed to block a Dominion Post photographer from taking pictures within the gates, two photos of the set have already surfaced online.
The photos depict an old house situated in front of a green screen.
While the Fire Service has signed a confidentiality agreement with Weta Workshop and Stone St Studios, Jackson’s spokesman, Matthew Dravitzki, said he believed the alarm to be a false one.
Sir Peter Jackson’s workers were scheduled to resume working yesterday.
