The location is nice and the park has a few cool animals and photo opportunities such as the small waterfall or the raised trout exhibit.
The bird show was ok. Nothing amazing but worth a watch.
The kiwi were good to go and have a peak at. The behind the scenes tour wasn't very intriguing but we did get to see some kiwi chicks :)
The biggest let down for me was when we went through the gift shop and one of their photographers tried charging us $40 for one photo. Pretty insulting.
Overall a great place to bring the kids.
