The logo selected for SRARNZ is one element of the famous "Opihi Taniwha" rock drawings. These Maori rock drawings, executed in charcoal on the roof of a low limestone overhang near the Opihi River (South Canterbury, New Zealand), are believed to be about 500 years old. Together the two elements are over 5 metres long and the artist, lying on the ground, would have been able to see only a small portion of them at any time. Lizards, especially geckos are revered by the Maori people and the lizard form is often used in Maori art. The creatures in the "Opihi Taniwha" drawings appear to be stylised representations of reptiles; the broad head, wide body and coiled tail of the animal in the drawing used for the logo are suggestive of a gecko.
