Wesfarmers has joined a growing list of retailers admitting to staff underpayment.
Sunglass Hut, Michael Hill, MJ Bale and Super Retail Group are among those implicated in recent wage theft scandals.
Now, Wesfarmers has admitted to underpaying Target staff by $9 million.
This is the second strike for the retail group, which underpaid employees in its workwear division $15 million.
These “payroll errors” now equate to $24 million.
MD Rob Scott said the issue is under investigation.
“Immediate steps are being taken to rectify identified issues, notify and repay affected team members, including interest, and ensure accuracy in the future through a robust program of auditing and monitoring."
The issue was announced during a profit announcement for the first half of the financial year.
Kmart Group, which includes Kmart and Target, saw a revenue increase of 7.6% to $4.990 million for the half.
Kmart sales increased $241 million, offsetting a sales decline of $67 million in Target.
Earnings fell 9.9% to $345 million, however this includes a one-off provision for that payroll remediation in Target.
Excluding this provision, earnings fell 7.6%.
