This is a Aotearoa native Gecko. They are quite rare now as cats have thinned their numbers a lot. The problem with native animals here is that they are not good at dealing with the foreign invaders like cats, dogs, rats, stoats, ferrits... I don't know a lot about Geckos. When I was a kid I used to keep the ones that my cat brought inside (yes, I am part of the problem) as pets. This one was really small. Smaller than your index finger. Yes, YOUR index finger.
