Investigating Bullying: How to Differentiate Between “Bad Behaviour” and a Legally Defensible Bullying Finding (NZ + Australia Guide)

“Bullying” is one of the most emotionally loaded words in the workplace.
Employees fear saying it.
Leaders fear hearing it.
HR fears managing it.

Across New Zealand and Australia, bullying has a specific legal definition — but most people use the term to describe a wide range of behaviours, from poor communication to micromanagement, interpersonal tension, personality clashes, stress responses, or even normal performance management.

When organisations don’t understand the difference between:

  • inappropriate behaviour,
  • poor leadership,
  • miscommunication,
  • reasonable performance management, and
  • actual bullying,

they risk:

  • unfair findings,
  • traumatising staff,
  • wrongful termination,
  • emotionally damaging processes,
  • expensive legal claims,
  • loss of trust,
  • escalation into conflict or personal grievance.

This HR Unlocked guide shows you how to assess bullying allegations safely, clearly, and in line with the law in both NZ and Australia.

1. The legal definition of bullying (NZ + AU)

Despite the emotional intensity, bullying has a very specific meaning.

Across NZ’s WorkSafe guidance and AU’s WHS laws, bullying is:

Repeated and unreasonable behaviour directed towards a person that creates a risk to their health and safety.

Let’s break this down:

 Repeated

More than once.
One-off incidents (even very upsetting ones) are not bullying — though they may be misconduct.

 Unreasonable

A reasonable person, in the same circumstances, would see the behaviour as inappropriate.

 Creates a risk

The behaviour must create risk to:

  • health,
  • wellbeing,
  • or safety.

This is a high threshold — and rightly so.

2. What bullying is NOT

Employees often label behaviour as “bullying” when they are:

  • stressed,
  • overwhelmed,
  • unsupported,
  • clashing with a personality style,
  • receiving corrective feedback,
  • under pressure,
  • confused about expectations.

Bullying is NOT:

  • performance feedback,
  • holding someone to account,
  • giving direction,
  • managing workloads,
  • enforcing standards,
  • addressing behavioural concerns,
  • occasional frustration,
  • a single incident,
  • conflict or miscommunication.

These issues may still need attention — but they are not bullying.

3. Step 1: Conduct a preliminary assessment

Before launching into a full investigation (which is costly, emotional and risky), conduct a preliminary assessment to:

  • understand the allegations,
  • gather broad facts,
  • identify patterns (or lack of patterns),
  • clarify whether the behaviour meets the threshold,
  • determine the correct process.

Most “bullying” complaints are actually:

  • conflict,
  • poor communication,
  • performance issues,
  • workload problems,
  • leadership style concerns.

A preliminary assessment prevents unnecessary escalation.

4. Step 2: Map the allegations against the legal definition

Ask:

  • “Is the behaviour repeated?”
  • “Is it unreasonable?”
  • “Does it create health and safety risk?”
  • “Would a reasonable person see it as inappropriate?”
  • “Is this interpersonal conflict, not bullying?”
  • “Is this leadership capability, not bullying?”
  • “Is this a single event that might be misconduct?”

If the allegations don’t meet all elements → it’s not bullying under the law.
But it may still require action such as:

  • coaching,
  • role clarity,
  • expectations reset,
  • conflict resolution,
  • performance management.

5. Step 3: Choose the right process

Based on the assessment:

A. If allegations MAY meet the bullying threshold → formal investigation

Especially if:

  • multiple incidents,
  • repeated behaviour,
  • clear patterns,
  • multiple complainants,
  • health impacts,
  • documentation exists.

B. If allegations fall short → alternative pathways

  • facilitated conversation
  • conflict coaching
  • expectations reset
  • performance management
  • leadership coaching
  • team culture work
  • workload review

The wrong process creates more harm than the behaviour itself.

6. Step 4: Conduct a fair, trauma-informed investigation (if required)

Bullying investigations require skill.
Poorly run investigations retraumatise people.

A safe investigator must:

  • be neutral,
  • understand bullying definitions,
  • assess evidence without bias,
  • avoid emotive language,
  • interview sensitively,
  • test evidence properly,
  • write clear findings linked to law and policy,
  • avoid credibility judgments based on emotion.

Most internal teams lack the capability — external investigators are often safest.

7. Step 5: Assess evidence against EACH element (repeated + unreasonable + risk)

A bullying finding requires ALL three elements.

Example:

ElementEvidence?Outcome
RepeatedYes — behaviour occurred 6 times
UnreasonableYes — witnesses confirm behaviour was inappropriate
RiskYes — complainant had medical documentation / sick leave / impact
FindingBullying substantiated 

But if even one element is missing:

ElementEvidence?Outcome
RepeatedNo — only one event
FindingNot bullying, but conduct/miscommunication may need addressing 

Clarity protects fairness.

8. Step 6: Provide the right outcome (bullying vs behaviour vs conflict)

If bullying IS substantiated

You must:

  • address the behaviour
  • protect safety
  • consider disciplinary action
  • put a safety and wellbeing plan in place
  • monitor relationships
  • strengthen team culture
  • train leaders

If bullying is NOT substantiated, but behaviour is inappropriate

You must still act:

  • letter of expectation
  • coaching
  • behaviour agreement
  • training
  • conflict resolution

If the issue is conflict

Use:

  • facilitated conversations,
  • mediation,
  • team reset,
  • communication coaching.

If the issue is performance

Use:

  • PIPs,
  • clarity work,
  • leadership development.

Every scenario has a correct path — not everything requires an investigation.

9. The human side: bullying allegations are emotionally heavy

For complainants:
They may feel:

  • scared,
  • exhausted,
  • overwhelmed,
  • ashamed,
  • angry,
  • traumatised.

For respondents:
They may feel:

  • shocked,
  • defensive,
  • distressed,
  • misunderstood,
  • judged,
  • afraid for their job.

Your role is to maintain:

  • neutrality,
  • clarity,
  • dignity for both parties,
  • safety,
  • consistent communication,
  • procedural fairness.

One HR Unlocked client said:

“Your bullying assessment framework helped us make fair decisions instead of reacting emotionally. Staff said they felt respected — even when the outcome wasn’t what they hoped for.”

That’s what good HR does — keeps people safe while keeping the process fair.

The bottom line

Bullying allegations require clarity, calmness, and fairness — not panic.

Across NZ and Australia, the safest and most effective approach is to:

  • triage first,
  • use legal definitions correctly,
  • avoid over-escalation,
  • choose the right process,
  • conduct fair investigations when needed,
  • separate bullying from other types of issues,
  • communicate clearly,
  • treat all parties with dignity.

Handled well, bullying complaints become moments of cultural learning rather than emotional implosion.
