This award-winning documentary from NHNZ reveals new information about the origins of the iconic kiwi. Presenter Peter Elliott travels the country investigating how "evolutionary mutants" — like giant meat-eating snails, kiwi, and tuatara — evolved over 20 million years in the face of massive tectonic upheavals and extreme isolation.  Elliott answers why Aotearoa has the "weirdest creatures", such as birds that don't fly and mammals that do. Company Weta Workshop used computer graphics to create images of extinct creatures for this TV One documentary.
