The seven month investigation into the cause of the rockslide in the Mangorewa Gorge on August 6 last year is complete, but investigators were reluctant to attribute blame.
Department of Labour Bay of Plenty service manager, Murray Thompson says it appears the parties involved at the time had taken all practicable steps to ensure the safety of their employees, contractors and sub contractors and other people in a place of work.

'Our investigation found that there is no indication a specific action or inaction of the principal or their contractors led to the rock fall and as such, the department does not intend taking any further action.”
The rock fall came from an overhanging section near a construction work site involved in the widening of the existing road.
The construction required the removal of rock from the gorge walls. Three members of the public were injured in the incident.
'No single cause for the rock fall could be determined and we are satisfied that the Principal and contractor's engaged and followed ‘expert' advice.”
The Department of Labour has informed the injured people and all the parties involved of the outcome of its investigation.
