A video of an interview with Andy Cole, site supervisor at Geovert, about the procedure for blasting rocks in Hillsborough. The rock-blasting work was paid for by two Christchurch couples whose properties were red-zoned and red-stickered. The couples hope that the blasting work will encourage CERA to change their land zoning from red to green, allowing them to rebuild their homes on the same sites.
