The “Million Dollar Boulder” on Kaikoura slip 7 is finally down at road level. After 6 months of harassment by helicopters, sluice buckets, abseilers and geotechs the 300 ton boulder is finally given the big Amex shove. 120 kg of Orica Amex strategically positioned behind the boulder (by aerial antics) followed by the push of a tiny button was all that was required to shatter and dislodge the monster.

The next blast, in a few weeks time, is “Rocky Balboulder” 800t…

Rocky blast

The closure of State Highway 1 both sides of Kaikoura after ex-cyclone Gita had a silver lining for the North Canterbury Transport Infrastructure Recovery (NCTIR) team: they had a chance to blow up a large boulder while no one was on the road. Check out this amazing footage.
