Nearly 100 percent of the state highway network and two thirds of the local roading network are sealed. Chipseal is the most common type of road surface in New Zealand. Economical, flexible and hardwearing, it provides an adaptable, cost-effective and safe surface for road users. The NZTA regularly monitors all chipseal surfaces to make sure they continue to perform at their best.
