She should be able to take it back with her. As far as the electricity connection goes, all she needs to do is buy an adaptor when she gets back to New Zealand. All the travel stores and most Post Offices sell them. I purchased my Pfaff from England, got myself an English to Australian adaptor, and there were no problems at all. Perhaps she will have to pay for excess baggage because of the weight of the machine but I cannot see any problems with her taking it back with her. By the way, congratulations on your win.
