"Instead of paying the workers what they were legally entitled, SSL paid them for what they deemed 'productive hours' only – which the company calculated as the amount of trees needed to be pruned or planted, divided by the expected hours to do them."
The determination was limited to underpayments of the four identified workers, but the ERA also determined the company benefited by as much as $1.6 million over six years, as SSL's own accountant identified.
"What would have made it more difficult on these workers was that about half of SSL's workforce usually comprised of migrant staff on 'tied' visas, meaning their visas allowed them to only work for SSL," Finnegan said.
"Fear can dissuade workers from coming forward in these situations.
"But the Inspectorate encourages anyone who has information about minimum standards not being met to phone the MBIE's service centre, where calls will be handled in a confidential manner, on 0800 209020."
SSL is a subsidiary of CNI Forest Management Limited, based in Rotorua, and employs up to 250 staff in forestry block growing and maintenance.
