A week is quick trip to New Zealand - especially since you've come such a long way. But if you've got 7 days then pick an island, any island. Although, we recommend the North Island for a short period. Start in Auckland,at the Waitomo Caves and Hobbiton before heading to the geothermal wonders of Rotorua. Then explore Lake Taupo and Tongariro National Park before finally getting to know the hilly neighborhoods and picturesque harbor of Wellington. Your week in New Zealand will fly by, sadly.
