The Employment Relations (Triangular Employment) Amendment Act 2019 (‘the Act’) amended the Employment Relations Act 2000 to address a longstanding gap in New Zealand employment
law for ‘triangular’ work arrangements. Triangular work is where:

1. An employee is employed by one entity (the ‘employer of record’), but
2. Works under the control or direction of another organisation (a ‘controlling third-party’), and
3. The third-party benefits from the employee’s work.

Before this change, employees could raise personal grievances only against their direct employer, even if the controlling third-party was the one directing their day-to-day tasks. The law change
now allows for controlling third parties to be joined to personal grievance proceedings under certain conditions.
