DOWN UNDER Air New Zealand has opened a marketing campaign designed to try and persuade Aussies to cross the Tasman Sea and visit the North and South Islands. They have recruited Peter FitzSimons, Australian rugby union great and acclaimed author, to front the largest promotion Air New Zealand has ever undertaken in Australia, a bold step, which could be compared with the idea of Zinedine Zidane, working in France promoting British Airways . But whether Australian holidaymakers will turn towards the generally more colder south than Asia and the Pacific remains to be seen. In another promotional move ANZ is to rename its entire international fleet after key New Zealand destinations, starting with the airline's eight Boeing 747s. The soon-to-be refurbished 747 aircraft will be named after Auckland, Bay of Islands (at the top of the North Island), Christchurch, Dunedin, Kaikoura, Rotorua, Queenstown and Wellington.
