That last photo of the Tuatara is stunning, that's not through glass is it? I could never get a decent shot of one through the thick glass that was in every enclosure we saw....the ones that we in cages were never out because it was the middle of Winter! North and South Islands, we went to pretty much every wildlife sancturay and Museum that had them, and my best shot is this one. It's sad! It's great to see a pic like yours.
I've only got a Cannon A80 4mp at the moment....2 1/2 years old. Which camera are you using?
My missus only needs to take one breath in an hour when she's berating me! We went to Rotorua a couple of times last year, now I know where she learned it!
