Employment Relations Act 2000, ss 4, 60, 63A
If you and your employer are negotiating a new individual agreement or negotiating any specific new terms, you must deal with each other in good faith. This duty of good faith includes not misleading or deceiving each other.
Employers also have some other specific obligations when negotiating individual agreements, and this applies both to existing employees negotiating new agreements (or changes to an agreement) and to prospective employees. In these situations the employer must:
give you a copy of the proposed agreement
tell you that you have the right to seek independent advice about the agreement, and give you a reasonable opportunity to get it, and
consider any issues you raise, and respond to them.
