A practical guide to an Employment Relations Authority investigation: filing, case management, witness statements, evidence, the investigation meeting, remedies, costs and preparation.
The Employment Relations Authority (ERA) decides employment disputes when they cannot be resolved through negotiation or MBIE mediation. The ERA runs an investigation meeting process and issues binding determinations, including remedies, penalties, and costs.
The Employment Relations Authority (ERA) is where many employment disputes end up when they do not resolve through direct negotiation or MBIE mediation. The ERA investigates the facts and makes a decision called a determination, which is legally binding.
People often assume the ERA is like a traditional court hearing. In practice, the ERA is an investigative process. The Authority Member will usually ask most of the questions, work through the issues, and test the evidence from both sides.
The ERA covers "employment relationship problems" which can include personal grievances (PGs), wage and holiday pay disputes, and other problems arising out of an employment relationship. It is not only for employees - employers also bring claims in the ERA.
Before you file in the ERA, the usual pathway is:
Your application (Statement of Problem) should be written in plain language and set out:
The more structured and evidence-based the Statement of Problem is, the better the case will run later. Poorly drafted applications cause delay, confusion, and unnecessary concessions at the investigation meeting.
The investigation meeting is where each party presents their case to the Authority Member. It is less formal than a court hearing, but it is still a serious evidential process.
The ERA issues a legally binding determination. Depending on the case, the ERA can award a range of remedies and orders.
Filing in the ERA has set fees (including a lodgement fee and investigation meeting fees). Separately, costs awards (contributions to costs) are discretionary and are often much lower than what a party actually spent on representation.
This costs reality matters for employers and employees: it affects settlement strategy, Calderbank offers, and whether "digging in" is commercially sensible even if you believe you will win.
