The Government has announced changes to employment laws to clamp down on the exploitation of vulnerable workers.
The changes include tougher sanctions, increased tools for labour inspectors and clearer record-keeping requirements.
Workplace Relations Minister Michael Woodhouse said the Government was particularly concerned about the exploitation of vulnerable workers such as migrant workers.
He said stronger sanctions for serious breaches would send the message that exploitation is unacceptable.
Fines will be increased fivefold, and individuals could be banned as employers if they commit serious or persistent breaches of employment standards.
The legislation will be introduced to Parliament around the middle of this year.
