The New Zealand State Highway network is the major national highway network in New Zealand. Just under 100 roads in both the North and South Islands are State Highways. All state highways are administered by the NZ Transport Agency.
The highways were originally designated using a two-tier system, national (SH 1-8) and provincial, with national highways having a higher standard and funding priorities. Now all are state highways, and the network consists of SH 1 running the length of both islands, SH 2-5 and 10-58 in the North Island, and SH 6-8 and 60-99 in the South Island, numbered approximately north to south. State highways are marked by red shield-shaped signs with white numbering (shields for the former provincial highways were blue). Road maps usually number state highways in this fashion.
