Road Surveying after the Kaikoura earthquake
Earthquakes hit roads hard. After the devastating Kaikoura earthquake in New Zealand, the main State Highway (SH1) had to be partially closed.

The New Zealand Transport Agency (NZTA) is actively monitoring for any deterioration to the diversion road to ensure it remains in good condition and as part of highway asset management good practice....
