The document discusses managing and maintaining New Zealand's critical state highway assets from a maintenance perspective. It describes the state highway network, which comprises 11,000km of road and relies on bridges, culverts, and other structures. Maintaining the network faces challenges from New Zealand's variable climate and rugged landscapes, which see rainfall vary widely and include flooding, earthquakes, slips, and scouring. The document highlights examples of maintenance for highways in both the North and South Islands, such as addressing slips and rockfalls on SH6 on the West Coast and seismic retrofitting of bridges.
