I did last March a RTW on Global Explorer with a stop in Fiji, where I had to fly AKL-NAN-AKL. Return flight was NAN-AKL-SCL-EZE without stop-overs. Stayed in Fiji at Treasure Island for 5 nights between a week tour in NZ's south island and visits in Buenos Aires Mexico City. Fiji's Treasure Island was the perfect place for relaxing in a pacific island environment.
