We are planning on visiting Australia and N. Z. 2014 (Nov.) from Canada. Would like to fly into Cairns Australia and take a bus tour down the Eastern coastline to Sydney (have friends there) stay a week and then fly into New Zealand and rent a car and do our own touring (month). Wondering if it is better to fly into Christchurch or Auckland and get a car? Is there one company that will allow you to take the car to both islands and have a different drop off point? Are accomodations easy to get that time of year? We are not booking ahead. All suggestions appreciated.
