We have accepted an enforceable undertaking from Hiway Stabilizers NZ Limited.


On 03 December 2019, while attempting to clear debris near an open void on a Komatsu GS360 Stabilizer Machine, the victim's foot missed the debris and went inside the void. His foot became entangled in the still rotating axle and his leg was drawn into the void and was amputated below the knee.

Alleged Breach

Health and Safety at Work Act 2015, S 36(1)(a), 48(1) and 48(2)(c)
The alleged contravention does not amount to an offence against section 47 (reckless conduct) which would preclude it from being accepted.
