Today marks two-years since the magnitude 7.8 earthquake rocked the Kaikoura and Hurunui districts, killing two people and tearing roads and infrastructure apart.
GNS says it was one of the most complex quakes ever recorded worldwide, with 14 of 21 fault ruptures - surfacing.
It caused tens of thousands of landslides in a 10-thousand kilometre squared area.
Rebuilding Kaikoura's State Highway One and the Canterbury to Picton rail line - has cost more than one-billion dollars.
Over the past three-decades, landslides have cost New Zealand an overage of 300-million-dollars a year.
