Awesome photo's Debbie!
Naultinus love small leaf shrubs like Coprosma propinqua. If you google the names you'll be able to find some similar plants. Leptospernum is great, they live on this in the wild. Think small leaves & you'll have a VERY happy gecko. In the wild they love to shelter amongst dense clumps of vegetation, where plants have a tangle of leaves & branches. This is the same for my own captive New Zealand geckos.
Check out these baby Naultinus grayi - very cool & sooo cute!
Nice! where do buy these geckos from?
