You will find rental cars in christchurch in two main places in this Garden City. Well, actually Christchurch has good, reliable car rental companies in a number of places through the city. All of them equally affordable and so on. But for a tourist who needs reliable cars at a good price there are two main place: either out by the airport in the commercial zone around the Eastern side of that busy tourist hub; or around the central part of the city, near Cathedral Square and the business and shopping district there. As I say, rental cars from either place are reliable and affordable.
