The Industrial Relations Act 1999 (PDF, 1.9MB) prescribes a number of rules about how wages are to be paid to employees.
An employer must pay wages to their employees without deduction - except if those deductions are authorised by the employee in writing or if the deduction is authorised by the Act.
The Act gives the right to an employer to make deductions from an employees wages only where the employee has been paid an amount to which they are not entitled because of absence from work (e.g. an overpayment resulting from leave taken when no entitlement exists).
