Off the east coast of the North Island of New Zealand, dive deep into the clear and picturesque waters of the Poor Knights Island Marine Reserve, where you'll observe a beguiling mix of colorful deep-sea creatures. Beloved marine explorer Jacques Cousteau called the locale one of the 10 best dive spots in the world. John Sweetman narrates the program, which features music by Indigenous Australia, Wiremu Karaitiana and Matt Kemara.
