We are going on a conducted tour to NZ in May 2014 for 10 days and will land in Auckland and cover Rotorua, Queenstown, Franz Josef and Christchurch. Which is the best SIM Card operator which will cover our International Telephone calls to India from all these places and also Internet facilities and can you purchase the SIM Card from the Auckland Airport when you land. Also is it possible to top up the
credit at Departmental stores. Shall be glad if someone can let us know the details including costs, departmental stores etc. so that we are mobile as soon as we land in NZ. Will appreciate any advise. Thanks in advance.
