Victoria University's resident tuataras are on the move.
A special event is being held on Friday to welcome the tuataras to an enclosure in the Wellington university's newly-built science building.
As staff move to their new offices and laboratories, so will four reptiles - Spike, Hazel, Shorty and Phoebe - that live at the university.
"The new enclosure has been designed to have all the components that we think keep tuatara happy: dappled sunlight, plants, burrows and heat lamps," associate professor Nicola Nelson said.
"We want the transition to be as easy as possible for the animals, we'll be watching their behaviour carefully and staging their move to ensure it's not stressful and they have time to become familiar with their new home."
The tuataras have been based in their current enclosure since 1996.
The lizards have donated samples to various student research projects over the years, including for studies investigating hormone and vitamin levels.
The university also incubates the tuatara's eggs as part of conservation programmes around the country.
