WorkSafe New Zealand have been called in over concerns a radio stunt that saw a car blown up was unsafe and illegal. Thane Kirby, a DJ on The Rock, organised for his Rock Drive co-host Duncan Heyde’s old Honda to be destroyed with 55kg of explosives. However the managing director of a commercial explosives company has contacted WorkSafe with concerns the explosion was "irresponsible" and did not comply with laws around the handling of explosives.
