I have 7 full days, and two partial days, to travel in New Zealand. I'm flying into Auckland, and then need to return to Auckland. I'm struggling to decide whether to stay in the North and visit Waitomo/Rotorua/Taupo/Tongariro, head to the South Island and visit some (but not all) of Abel Tasman, Milford Sound, and the glaciers, or try to do some combination (some of the north, plus Abel Tasman). Any suggestions? I'll be there from the end of November and early December, so I need to decide soon! I'm traveling with 2 other people.
