Asphalt driveways are generally more affordable to install than concrete driveways. The cost of a concrete driveway in NZ can range from $120 to $180 per square meter, while asphalt is typically less expensive. However, concrete driveways tend to last longer (up to 30 years or more), though they may crack more easily without proper maintenance. Asphalt driveways, while slightly less durable, are easier and cheaper to repair and maintain over time.
