Part 3 of the Bill relates to enforcement. Section 15 provides that a complaint by an employee, or by a trade union of which the employee is a member, that the employer has contravened any provision of the Bill in relation to that employee, may be presented to a rights commissioner who shall issue a written decision in the matter and communicate that decision to the parties. The decision of the rights commissioner may require the employer to pay compensation, subject to a limit of two years of the employee's remuneration. A complaint to a rights commissioner must be made within six months of the date of contravention of the Bill or the date of termination of the contract of employment concerned, whichever is the earlier. This period may be extended by a further 12 months if the commissioner is satisfied that failure to refer the case within six months was due to reasonable cause. The hearing before the rights commissioner shall be conducted in private.
