When you are asking for affordable rental cars in Christchurch there is one thing you need to inquire about. The hire and the rental rates. Make sure you pick up the rates that are right for your tour. If you are going to travel the South island, then expec t to pay a little more, because that is a long tour. It will take you several days, for instance, just to get to the Haast Pass. That will take you in a rental car to Queenstown and the lovely Sound that is a day-long drive away on the Tasman Ocean. There are other things to see on a South Island trip, in a rental car, but those are what people these days seem to most want. So factor that in when you are pricing hire cars in Christchurch.
