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.
