Department of Conservation Te Anau staff are "devastated" after a much-loved gecko at the local visitor centre was taken.
Graham, a Marlborough green gecko, had been in his terrarium at the Fiordland National Park Visitor Centre for 30 years.
Staff noticed he was gone on Wednesday. The padlock to his terrarium was missing and marks on the latch pointed toward it having been forced or cut.
Doc operations manager (Te Anau) Greg Lind said it was distressing to think the gecko, that had lived in one place all its life, might be subjected to uncomfortable experiences.
"The gecko has a distinctive grey mark on its head and would be easily identified. It's our longest serving advocacy animal in Fiordland, and staff just want it back safe.
