One of our staff wants to go to Oz for a short visit and use a mobile t-stick over there. Telecom is quoting $8000/GB for data roaming (!!) so I think we're going to buy something in Australia. Which is the best deal (for t-stick+data) that will also be usable back in NZ? Do they still have their horrendous registration process (took me about 4 hours to work round it a few years ago)?
