Conduct vs Capability: Managing Employee Performance Issues In New Zealand Lawfully

byAlex Solo10 min read

Employee performance issues are a normal part of running a small business - especially when you’re growing, hiring new people, or managing a busy team with changing demands.

But when performance problems start affecting your customers, your team culture, or your bottom line, it’s important to act early (and to act lawfully). In New Zealand, managing employee performance issues isn’t just about “having a chat” or issuing a warning. Your process needs to be fair, well-documented, and consistent with your legal obligations as an employer.

A big part of getting this right is understanding one key distinction: is this a conduct issue, or a capability issue?

Once you correctly classify the problem, you can follow the right process - and avoid turning a fixable workplace issue into a costly personal grievance.

What’s The Difference Between Conduct And Capability?

Many employers use “performance” as a catch-all term. In practice, performance problems usually fall into two broad categories:

  • Conduct: the employee can do the job, but they’re choosing not to follow rules or meet behavioural expectations.
  • Capability: the employee is trying, but they’re not meeting the required standard due to skills, competence, health, or aptitude issues.

It sounds simple, but the difference matters because you generally deal with them through different policies, meetings, evidence, and (often) different timeframes.

Examples Of Conduct Issues

A conduct issue is usually about behaviour, compliance, or attitude. For example:

  • Repeated lateness or unexplained absences
  • Failure to follow reasonable instructions
  • Bullying, harassment, or inappropriate language
  • Refusing to complete tasks they are capable of doing
  • Misuse of company property or systems
  • Conflicts of interest or side gigs that breach expectations

If you rely on policies to manage behaviour (and you should), this is where a clear Workplace Policy and tailored expectations in your Employment Contract become essential.

Examples Of Capability Issues

A capability issue is usually about competence, skill, or ability to do the role at the required level. For example:

  • Consistently missing deadlines despite trying
  • Not meeting sales or output targets after training and support
  • Ongoing errors or quality issues
  • Difficulty learning systems needed for the role
  • Inability to perform certain duties due to medical or health issues

Capability issues often require more coaching, support, and a structured improvement plan - not a quick disciplinary response.

Why Getting The Category Right Matters (And How It Affects Risk)

From a legal perspective, the biggest risk for employers isn’t usually that you addressed performance issues - it’s that you addressed them without a fair process, or treated the employee as if they’d done something wrong when the real problem was capability (or vice versa).

In New Zealand, employment relationships are governed by obligations of good faith (Employment Relations Act 2000). That means you generally need to be open, communicative, and fair - including when performance problems arise.

If you misclassify the issue, you can end up with problems like:

  • Unfair disciplinary process (for example, issuing warnings for what is really a training/competence issue)
  • Unjustified dismissal claims if you terminate without a solid, well-run process
  • Discrimination risks (for example, where health, disability, or family responsibilities are involved)
  • Inconsistency across staff, which can make it look like you’re targeting one person unfairly

As a small business owner, you’ll often be balancing legal requirements with practical realities: keeping the business running, supporting the team, and being fair to the employee involved. The key is to follow a process that is clear, consistent, and properly documented - even if you keep it straightforward.

What Is A Lawful Process For Employee Performance Issues In NZ?

There isn’t a single “one-size-fits-all” process, because what’s fair depends on the situation (including the seriousness of the issue, the employee’s role, and what you’ve done previously).

That said, most lawful approaches to managing employee performance issues follow a similar structure. If you’re unsure, it’s often worth getting support early - not at the end when things have already escalated.

This is also where having a clear Performance Management Process can make a huge difference, because you’re not building your approach from scratch under pressure.

1) Identify The Problem Clearly (And Gather Evidence)

Before you meet with the employee, get specific about:

  • What the issue is (for example: “late to shift start time 6 times in 3 weeks” rather than “unreliable”)
  • When it happened (dates, times, impacted shifts/projects)
  • What expectations apply (contract, policy, KPIs, training materials, role description)
  • What impact it’s having (customer complaints, safety risk, team disruption, rework costs)

Try to avoid going in with assumptions about intent. Focus on observable facts.

2) Meet With The Employee And Explain The Concerns

Usually, you’ll start with an initial discussion. Depending on the seriousness, this might be an informal meeting - but it still needs to be fair.

At the meeting, you’ll generally want to:

  • Explain your concerns clearly and calmly
  • Give the employee a real chance to respond
  • Ask if there are underlying issues contributing (including health or personal issues)
  • Confirm what improvements are required

Even if you’re not at the “disciplinary” stage yet, keep notes of what was discussed and what was agreed.

3) Decide Whether It’s Conduct Or Capability (And Choose The Right Path)

Sometimes the employee’s response changes everything.

For example:

  • If they admit they knew the rules but didn’t follow them, you may be dealing with conduct.
  • If they say they’re struggling because they were never trained properly, you may be dealing with capability (or a systems issue on your side).
  • If there are medical issues involved, you may need to slow down and consider your obligations carefully before taking further steps.

If the situation is complex or already tense, getting advice early can help you choose a process that stands up if challenged later.

4) Provide Support, Set Expectations, And Put It In Writing

Whether the issue is conduct or capability, you’ll usually need to outline:

  • What improvement is required (and how you’ll measure it)
  • What support or training you’ll provide (if relevant)
  • Timeframes and review dates
  • What could happen if there’s no improvement (for example, warnings or termination)

Putting expectations in writing helps everyone stay on the same page - and protects your business if the employee later claims they “didn’t know” what was required.

5) Follow Through Consistently (Review Meetings And Documentation)

One of the biggest mistakes we see is employers starting a performance process, then letting it drift.

If you’ve told the employee you’ll review progress in two weeks, do it. If you’ve said training will be provided, deliver it. If you’ve said there may be consequences for continued issues, you’ll need to consider those consequences fairly if nothing changes.

Consistency is a big part of showing you acted reasonably.

6) If It Escalates, Use A Proper Disciplinary Or Termination Process

Not every performance issue ends in termination - and ideally, many don’t. But sometimes you reach a point where the employee can’t (or won’t) meet the requirements of the role.

If you’re considering dismissal, the process becomes even more important. Termination that isn’t carried out fairly can lead to significant cost and stress for a small business.

At that stage, it’s common to rely on a structured package like an Employee Termination Documents Suite so your letters, meeting steps, and record-keeping are consistent and legally appropriate. You’ll also want to be across the right approach to How To Terminate An Employee, because the “how” matters just as much as the “why”.

How Do You Manage Conduct Issues (Discipline) Fairly?

Conduct issues are often dealt with through a disciplinary process. The aim isn’t to “catch the employee out” - it’s to address the behaviour, give a fair chance to respond and improve, and protect the workplace.

Start With The Right Questions

Before you go down a disciplinary path, ask:

  • Is there a clear rule, policy, or instruction the employee failed to follow?
  • Was the rule reasonable and clearly communicated?
  • Have other employees been treated the same way for similar behaviour?
  • Is the behaviour serious enough to justify discipline (or is it better handled informally first)?

Investigate First (Especially For Serious Allegations)

If the allegation is serious (for example, theft, harassment, violence, serious safety breaches), you generally need to investigate before making findings.

A fair investigation might include:

  • Collecting documents (messages, rosters, system logs)
  • Interviewing witnesses (appropriately and confidentially)
  • Giving the employee details of the allegations
  • Letting the employee respond before decisions are made

Be careful with how you collect and store information during an investigation. If you’re handling sensitive employee information, a resource like an Employee Privacy Handbook can help you set clear boundaries around access, retention, and confidentiality.

Make Sure Meetings And Warnings Are Procedurally Fair

Even where the issue seems straightforward, disciplinary action should generally follow a fair process. This often means:

  • giving the employee notice of any disciplinary meeting and the concerns to be discussed
  • providing relevant information you’re relying on (where appropriate)
  • allowing the employee a reasonable opportunity to take advice and bring a support person or representative
  • genuinely considering their explanation before making a decision

Warnings (verbal or written) should generally explain:

  • What the employee did wrong (with specifics)
  • What policy/expectation applies
  • What improvement is required going forward
  • How long the warning will remain active (where relevant)
  • What may happen if the behaviour continues (including termination in serious/repeated cases)

One practical tip: avoid “cookie-cutter” warnings. Disciplinary steps should match the actual facts and your workplace documents.

Don’t Forget Behaviour Outside The Workplace

Sometimes conduct issues happen outside work hours (for example, social media posts, conflicts with clients, or behaviour at work functions). Whether you can take action will depend on the link to the workplace and the impact on your business.

This is another reason it helps to have well-drafted workplace expectations and policies from day one.

How Do You Manage Capability Issues (Underperformance) Properly?

Capability issues can be more time-consuming than conduct issues - but they’re also often the most fixable. Many performance issues are really about unclear expectations, poor training, or mismatched roles.

A good capability process usually focuses on support + structure.

Set A Measurable Standard

Employees can’t hit a target if they don’t know what the target is.

Depending on the role, a measurable standard could be:

  • Quality benchmarks (error rates, customer satisfaction outcomes)
  • Timeframes (job completion times, response times)
  • Output targets (units per shift, bookings per week)
  • Behavioural expectations that affect performance (professional communication, teamwork)

If your expectations are vague, it becomes harder to show that the employee failed to meet them - even if everyone “knows” the performance isn’t good enough.

Provide Training, Supervision, Or Adjustments Where Reasonable

In a capability process, you’ll often need to show you took reasonable steps to help the employee improve. That might include:

  • Additional training on systems or processes
  • Coaching, shadowing, or extra supervision
  • Clearer checklists or documented procedures
  • Adjusting duties temporarily to support learning

If health issues are involved, you may need to consider whether reasonable adjustments can be made (and whether medical information is needed). This is an area where tailored advice is especially important, because you’ll want to avoid stepping into discrimination risk while still managing the role requirements.

Use A Performance Improvement Plan (PIP) Carefully

A Performance Improvement Plan can be helpful, but it needs to be realistic and fair. For small business owners, the best approach is usually:

  • Keep the plan simple and role-specific
  • Confirm support you’ll provide
  • Set review points (and keep them)
  • Document progress objectively

A PIP shouldn’t be treated as a “paper trail to terminate someone.” If it looks like the outcome was predetermined, that can increase your legal risk.

Consider Redeployment Or Restructuring If The Role Is The Problem

Sometimes underperformance is actually a mismatch between the role and the employee (or the role has changed over time).

If the position has genuinely changed and the employee can’t meet the new requirements, you may need to consider restructuring options. In that case, it’s worth getting advice early - for example, through Redundancy Advice - because redundancy has its own consultation and process expectations, separate from performance management.

Key Takeaways

  • Most performance issues fall into either conduct (won’t do) or capability (can’t do), and the correct category affects what process you should follow.
  • A lawful approach usually involves clearly identifying the issue, meeting with the employee, giving them a genuine opportunity to respond, setting expectations in writing, and following through with review steps.
  • Conduct issues often require a disciplinary process, including fair investigation (where needed) and proportionate warnings linked to clear workplace expectations.
  • Capability issues usually require structured support, measurable standards, training/coaching, and a realistic improvement plan before you consider termination.
  • Your employment documents and policies matter - they set the benchmark for expectations and make it easier to manage performance consistently and fairly.
  • If you’re heading toward termination, it’s critical to use a process that stands up legally, because a misstep can lead to personal grievance risk and significant cost for a small business.
