Why is New Zealand's landscape and flora and fauna so unique? In four-part series Moa's Ark, renowned English naturalist David Bellamy, with his impassioned enthusiasm and trademark beard (of "old man's beard must go" fame) goes on a journey to discover the answer. Directed and produced by Peter Hayden, this 1990 TV series was produced by Television New Zealand's award-winning Natural History Unit (now independent production company NHNZ).

Popular Greenstone series The Zoo aired for over a decade. The show went behind the bars at Auckland Zoo to meet monkeys, rhinos, kiwi, humans, and more. A family-friendly hit, initially for TV2, it sold widely overseas. The show spawned a number of spin-offs and best of DVDs, including two Zoo Babies specials, Trent's Wild Cat Adventures — plus Two by Two at the Zoo (2005) and The Zoo: This is Your Life (2011), which each featured one animal per episode. The Zoo won the viewers' vote for Favourite Documentary Series at the TV Guide Awards, seven years running.
