Freedom: A car rental will allow you the freedom to travel early or stay late and hence will allow you to go places as per your own wish and whim.
Comfort: You will agree that usually comfort is not used simultaneously with the public transport; a sense of comfort and personal space that a car rental endows will be far better.
Cost: Unlike Asia where the cost of public transport is usually very cheap, this is not the case in NZ. Here, a car rental will be a great choice if you want to save some cash while traveling.
Convenient: With a car rental you don’t have to wait for the bus, don’t have to worry about how to return during wee hours and no need to opt for expensive cabs as the last resort!
