Bubbling mineral springs and pools promise maximum relaxation in Rotorua, on New Zealand's North Island. Therapeutic hot mud pools, dramatic geysers and a buried village are within easy reach of the city. What happens in the bubbling mud geysers of "Rotovegas"—the area at the top of Fenton Street—stays in Rotovegas. Once you've made the most of the mud, soar nearly 2,000 feet on the Skyline Gondola for views of Lake Rotorua, then zip back down to explore the lake by paddle steamer, fishing charter or WWII amphibious vehicle.

The Māori call Auckland Tāmaki Makaurau — a maiden desired by 100 lovers, and a valuable territory fought over for centuries for its fertile land and natural harbours on the Pacific Ocean (to the east) and Tasman Sea (to the west).

More mild-mannered adventurers can take a quiet cruise through nearby Milford Sound, part of the Fjordland National Park World Heritage area, or sample South Island pinot noir from one of the region's 75 wineries.

Not far from the vibrant Surfers Paradise is the calm and collected Broadbeach, a refuge of honey-coloured sands.
