Facts in brief:
On 15 March 2016 the defendant and two employees entered the grain silo on a farm in Southland to assess the stirrer motors. No harm ensued.

On 16 March 2016, two electricians (the victim and a co-worker) entered the grain silo to wire up a motor that powers the grain stirrer. While the electricians were working inside, the outfeed auger on the silo was started. The defendant did not communicate to the electricians that the silo would be emptied. As a result, the grain inside the silo rapidly sunk down. The victim, who was standing at the time, sunk into the grain. The victim’s co-worker exited the silo, shut off the auger and raised the alarm that the victim was trapped. They managed to free the victim who was completely engulfed in grain.

The victim was transferred to Dunedin hospital via helicopter for a medical assessment and discharged later that afternoon. In total 15 people were exposed to the risk including emergency personnel.
