Setting up outdoor terrarium

[HummingBird]

My parents have just moved into a house that has a caged area next to it that was previously used for a dog (we assume). They have 9 whistling tree frogs in a tank right now and thought it'd be cool to make the cage into a terrarium for them. The area is about 1.5m x 3m x 1.8m tall. Has anyone got a similar setup? Any suggestions for suitable terrestrial plants? There isn't a heck of a lot of sun because it's on the southern side of the house. We were thinking maybe some bromeliads, but are there any NZ natives that would work? It'll be quite humid in there because we're going to have a large water section and a waterfall.
