The following safety benefits have been identified.
- Reduced risk of coastal hazards causing injury and loss of life e.g. as a result of more accurate evacuation advice in the event of tsunami.
- Improved civil defence resilience; reduced risk of damage to ‘engineering lifelines’ – roads, rail, water pipes, electricity transmission lines.
- Reduced risk of near-shore hazards for:
- recreational vessels
- shipping if the usual routes are unavailable or denied due to a maritime incident
- coastal shipping route(s) established in the aftermath of a weather event (for example the blue highway established to support the East Coast of New Zealand's North Island after Cyclone Gabrielle).
