Critical: The 90-Day Rule
Don't Miss This Deadline
You must raise a personal grievance with your employer within 90 days of the action or when you became aware of it. This deadline is strictly enforced. Extensions are rarely granted and only in exceptional circumstances.
Stage 1: Raising the Grievance
Timeline: Day 1 (must be within 90 days)
To formally raise a personal grievance:
- Put it in writing: Letter or email to employer
- State the issue: What happened and when
- State the type: Unjustified dismissal, disadvantage, harassment, etc.
- Request resolution: Ask for a meeting to discuss
Keep proof of delivery - send by email with read receipt or registered post.
Stage 2: Internal Resolution Attempt
Timeline: 2-4 weeks
Before external processes, you should attempt to resolve internally:
- Meeting with employer: Discuss the grievance
- HR involvement: If applicable
- Internal investigation: Employer may investigate
- Settlement negotiation: Many resolve here
You can bring a support person or representative to any meetings.
Stage 3: MBIE Mediation
Timeline: 1-3 months
If internal resolution fails, either party can request mediation through MBIE (Ministry of Business, Innovation & Employment):
Mediation Process
- Application: Online or by phone
- Wait time: 2-6 weeks for mediation date
- Duration: Usually 2-6 hours in one session
- Cost: Free (government funded)
- Success rate: ~70% of cases settle
Benefits of Mediation
- Free and confidential
- Quick resolution (weeks, not months)
- Flexible outcomes (not just money)
- Preserves relationships if needed
- Less stressful than hearings
If Mediation Settles
A settlement agreement is legally binding and typically includes:
- Compensation amount (if any)
- Reference terms
- Confidentiality clause
- Non-disparagement clause
- Full and final settlement clause
Stage 4: ERA Investigation
Timeline: 6-12 months total
If mediation doesn't settle the matter, you can apply to the Employment Relations Authority (ERA) for a formal investigation:
ERA Process Timeline
| Stage | Timeline |
|---|---|
| File application | Day 1 |
| Statement of problem filed | Within 28 days |
| Response filed by employer | 28 days after |
| Wait for hearing date | 4-8 months |
| Investigation meeting | Half to 2 days |
| Wait for determination | 1-3 months |
ERA Investigation Meeting
The ERA investigation meeting is less formal than court:
- Location: ERA office or via video conference
- Format: Inquisitorial (Authority member asks questions)
- Evidence: Documents and witnesses
- Representation: You can represent yourself or have a lawyer/advocate
ERA Determination
After the meeting, the Authority member issues a written determination:
- Wait time: Usually 1-3 months
- Remedies: Compensation, reinstatement, recommendations
- Costs: May order costs against losing party
- Appeal: Either party can challenge to Employment Court
Stage 5: Employment Court
Timeline: 12-24 months
If either party challenges the ERA determination, the matter goes to the Employment Court:
- Type: Full hearing (not appeal on law only)
- Process: Formal court procedures
- Wait time: 6-12 months for hearing date
- Hearing length: 1-5 days typically
- Judgment: 1-3 months after hearing
- Costs: Significant, typically need lawyer
Consider Carefully Before Court
Employment Court is expensive ($10,000-50,000+ in legal fees) and stressful. The outcome is uncertain, and you may be ordered to pay the other side's costs if you lose. Most cases should settle before reaching this stage.
