9. Motukawaiti, New Zealand

Motukawaiti, New Zealand, is in the stunning Cavalli Islands group. The 95 acre island is totally free of pests, making all stays pleasurable. Wild dolphins can be seen in the bay. What’s more, if the laid-back life of a private island resort appeals to you, this island is for sale. It has a luxury residence, modern spa facilities, swimming pool, guest cabins, and an extensive wine cellar built into the hillside. Power is self generated and stored on the island so that Motukawaiti is largely self-sufficient.
