Primeval New Zealand (2012)

We call ourselves Kiwis. But do we really know where "our" bird came from? The answer is astounding... and rather disturbing. To trace the origins of the kiwi and the rest of our weird and wonderful wildlife, we travel back through time - to Primeval New Zealand. For the first time science is revealing the true story about where our wildlife icons came from, and the reasons for their unique evolution.
