Health and safety operations general manager Ona de Rooy said there was no plan for the day Mr Epapara died laid out by the company.
"There was no `tailgate meeting' to discuss that day's work and there was no radio provided for Mr Epapara, a tree feller, to communicate with others.
"These are forestry basics that are fundamental to forestry safety and Complete Logging's failures led to Mr Epapara's death.''
Forestry companies must abide by the Approved Code of Practice for Forest Harvesting, Ms de Rooy said.
"If Complete Logging Ltd had applied it, the chances are Mr Epapara would be here today. Instead, a family and a community grieves over a preventable death.''
The forestry industry had an appalling year in 2013 with 10 men workplace deaths, she said.
Ms de Rooy said WorkSafe NZ's current programme assessing the safety of cable hauling operations was uncovering alarming systemic issues in the industry which contractors and the forestry companies employing them must address.
"Nearly half of the 162 assessments we've done have resulted in enforcement action (203 in total), and we had to shut down 15 operations because of serious, imminent danger to workers.
The Ministry of Justice was last year investigating whether corporate manslaughter charges, currently in place Britain and Australia, could be introduced in New Zealand.
However Prime Minister John Key told 3News there was a general belief they hadn't been successful in the UK and were difficult to prosecute.
