Computer Workstations And Ergonomics Obligations Under NZ HSWA

Note: This article provides general information about New Zealand law and is not legal advice. If you need advice for your specific situation, speak with a lawyer or health and safety professional.

If you run a small business, it’s easy to treat computer workstation ergonomics as a nice-to-have - until someone develops ongoing neck, shoulder or back pain, claims they’ve been injured at work, or you’re dealing with reduced productivity and increased sick leave.

Under New Zealand’s health and safety regime, workstation set-up isn’t just an “HR issue” or a “comfort issue”. It’s part of your legal duty to manage health and safety risks in the workplace - including risks that build up over time, like poor posture, repetitive strain, and sustained computer work.

In this guide, we’ll break down what computer workstation ergonomics under the HSWA compliance looks like in practice, what WorkSafe expects, and how to build simple systems that protect your people (and your business) from day one.

What Does HSWA Require For Computer Workstation Ergonomics?

The key legislation is the Health and Safety at Work Act 2015 (HSWA). HSWA sets up a broad, principles-based framework. That means you won’t find a single checklist inside HSWA that says “screen must be X cm away” - instead, you have a duty to eliminate or minimise risks to health and safety so far as is reasonably practicable.

If you’re a business owner, you’re likely a PCBU (a “person conducting a business or undertaking”). As a PCBU, you must ensure, so far as is reasonably practicable, the health and safety of:

• workers you engage or employ; and
• workers whose work you influence or direct (including some contractors); and
• other people who may be affected by your work (for example, visitors in a reception area).

In a typical office or “computer-based” business, ergonomic risks often arise from:

• poor chair support or incorrect chair height;
• desk height that forces awkward wrist/arm positions;
• screen positioning that causes neck strain;
• keyboard/mouse placement creating sustained shoulder or wrist tension;
• hot-desking or shared workstations without adjustment;
• working from home without a proper workstation set-up; and
• workload and deadlines that lead to long, uninterrupted screen time.

Even if an injury is gradual and no single event “caused” it, it can still be a work-related health issue you’re expected to prevent and manage under HSWA.

“So Far As Is Reasonably Practicable” (SFAIRP) In Plain English

This phrase shows up everywhere in HSWA. In practical terms, it means you’re expected to take steps that are reasonable in your circumstances, considering things like:

• how likely the risk is to occur (for example, prolonged computer work every day is a common and predictable risk);
• how severe the harm could be (chronic injury can be serious and expensive);
• what you know (or should know) about the risk and ways to control it; and
• the availability and cost of controls (and whether cost is grossly disproportionate to the risk).

For most small businesses, basic workstation ergonomics controls are relatively low cost, widely known, and easy to implement - which is exactly why WorkSafe expects you to take them seriously.

What “Computer Workstation Ergonomics HSWA” Compliance Looks Like In A Small Business

Compliance doesn’t mean having an expensive fit-out or hiring a full-time health and safety officer. It means you’ve got a practical, repeatable approach to identifying ergonomic hazards, assessing the risks they create, and then controlling those risks.

Here are the core building blocks that usually matter most for small businesses.

1. Identify Ergonomic Hazards And Assess The Risk

Start with the obvious: who is doing computer work, for how long, and on what equipment?

In practice, hazard identification and risk assessment might include:

• a simple workstation checklist (chair/desk/screen/keyboard/mouse positioning);
• asking workers if they have discomfort, pain, tingling, headaches or fatigue;
• checking whether people are using laptops without separate screens/keyboard/mouse;
• reviewing whether breaks are happening in reality (not just in theory); and
• looking for “work organisation” hazards (unrealistic deadlines, understaffing, constant overtime).

If you need to adjust staff hours or workloads due to health and safety concerns, it’s important you handle changes properly and fairly - especially if you’re changing rosters or expectations. (If you’re reviewing working patterns across the business, issues can overlap with reducing staff hours and how that’s implemented.)

2. Implement Controls (And Prioritise The High-Impact Fixes)

In ergonomics, controls often come down to three areas:

• Equipment (chair, desk, monitor, peripherals)
• Work set-up (positioning, adjustability, lighting, noise)
• Work design (breaks, task variety, reasonable pace)

Common workstation controls for office-based roles include:

• providing an adjustable chair with lumbar support;
• ensuring desk height works for the worker (or adding keyboard trays/risers);
• using an external monitor (or a laptop stand) so screens sit at a comfortable height;
• providing an external keyboard and mouse for laptop users;
• supporting sit/stand options where feasible (even a simple riser can help);
• setting expectations around micro-breaks and movement; and
• training workers on how to adjust their workstation for their body.

Tip: if you use hot-desking, it’s not enough to say “the workstation is adjustable”. You’ll usually need a system that ensures each worker knows how to adjust it and is actually doing so.

3. Provide Information, Training And Supervision

HSWA isn’t just about buying equipment. You also need to make sure workers understand what “good” looks like and feel safe to speak up.

This could include:

• a short onboarding session on workstation set-up;
• guidance notes or a checklist for self-assessments;
• a process for requesting adjustments (without stigma); and
• managers being trained to recognise early signs of discomfort and respond properly.

It’s also smart to ensure your documentation is consistent across your business - for example, your expectations around working from home, safe set-up, and reporting discomfort should align with your employment paperwork. If you’re hiring or updating terms, an Employment Contract is often where key obligations and processes can be reinforced (alongside your internal policies).

4. Monitor And Review Over Time

Ergonomics risks change as your business changes. Growth, new systems, new premises, and higher workloads can all increase risk - even if your original set-up was fine.

Monitoring can be simple, like:

• reviewing workstation set-ups every 6–12 months;
• checking in after role changes (e.g. someone moves into a more screen-heavy role);
• tracking discomfort reports and responding early;
• reviewing incident reports (including recurring pain or patterns of discomfort); and
• updating your approach when WorkSafe guidance or your equipment changes.

Do You Need To Manage Ergonomics For Remote And Hybrid Workers Too?

Yes - in most cases, you still have HSWA duties even when your team is working from home.

That doesn’t mean you can (or should) control someone’s home environment the same way you control your office. But it does mean you should take reasonably practicable steps to ensure remote work is safe.

For many small businesses, practical steps include:

• having a working-from-home safety checklist focused on workstation ergonomics;
• requiring workers to confirm their set-up meets basic standards;
• providing (or subsidising) essential equipment like a laptop stand, keyboard and mouse;
• allowing workers to take equipment home if they need it; and
• checking in regularly (especially for new starters or anyone reporting discomfort).

If you’re updating remote work arrangements, it can also be a good time to ensure your policies are clear and consistent (for example, expectations around safe set-up, reporting discomfort early, and what equipment the business will provide).

What Are Your Consultation And Reporting Duties Under HSWA?

A common misconception is that health and safety is something you “do to” workers (buy a chair, issue a policy, tick the box).

HSWA expects consultation and participation. That means you must, so far as is reasonably practicable:

• engage with workers about health and safety matters that affect them; and
• give workers reasonable opportunities to participate in improving health and safety.

When it comes to workstation ergonomics, consultation can be as simple as:

• asking workers what’s not working in their set-up;
• involving them in choosing equipment (within budget);
• trialling changes and asking for feedback; and
• making it easy to report pain early, before it becomes serious.

If someone does report discomfort or an injury, your response matters. The goal is early intervention and preventing further harm - not “pushing through” until it becomes a bigger issue.

Also note: HSWA has separate duties around notifiable events (for example, certain serious injuries, illnesses or incidents). Ergonomic discomfort and gradual pain will often be managed through your usual reporting and investigation process, but if an event is notifiable you may need to notify WorkSafe and keep records. When in doubt, get advice.

Sometimes, managing an ergonomics issue will involve sick leave, reduced duties, or temporary adjustments. If you’re navigating absence and entitlements, it helps to understand how sick leave works and how to align leave management with your broader HSWA duties.

What Legal And Practical Risks Come From Getting Ergonomics Wrong?

Ergonomics is one of those areas where small issues can quietly snowball into bigger legal and financial risk.

Some common consequences we see for businesses include:

• Injuries and ACC claims (including gradual process injuries affecting wrists, shoulders, neck and back)
• Lost productivity from discomfort, headaches, fatigue, and avoidable downtime
• Higher turnover if workers feel you don’t take wellbeing seriously
• Disputes and formal complaints if workers believe hazards and risks aren’t being addressed
• Regulatory scrutiny if there’s a pattern of issues or a serious failure to manage known risks

Just as importantly, poor ergonomics can create reputational risk. If your team shares that your workplace culture ignores health and safety basics, it can make hiring harder - especially in competitive talent markets.

How Do You Build A Simple Ergonomics Compliance Plan (Without Overcomplicating It)?

The best approach is one that your business will actually follow. A “perfect” policy that sits in a drawer won’t protect anyone - and it won’t help if something goes wrong.

Here’s a practical framework many small businesses use.

Step 1: Set Minimum Workstation Standards

Decide what a compliant workstation looks like in your business. For example:

• an adjustable chair or a chair with adequate support;
• screen at appropriate height (using a monitor or riser);
• keyboard and mouse positioned to avoid awkward postures;
• adequate lighting; and
• a clear process to request changes or equipment.

This is especially important if you have a mix of staff (part-time, casual, fixed-term, contractors) and a mix of locations (office, co-working, home).

Step 2: Create A Short Checklist And Make It Part Of Onboarding

Checklists work because they’re easy to follow and easy to prove you used.

A simple process might be:

1. worker completes a workstation checklist in their first week;
2. manager reviews it and addresses any red flags;
3. business implements changes (equipment, adjustments, training);
4. repeat after any move, role change, or injury report.

If you already run onboarding for role expectations and behaviour, consider aligning the ergonomics checklist with your broader workplace documentation (for example, policies issued alongside your Staff Handbook).

Step 3: Budget For Ergonomics Like You Budget For Any Other Essential Tool

Many small businesses hesitate because of cost. But basic ergonomic items are often cheaper than the hidden costs of injury, absence, and staff turnover.

You might set a simple annual budget for:

• chairs and monitor risers;
• keyboards/mice;
• footrests;
• standing desk converters; and
• one-off ergonomic assessments where required.

Step 4: Encourage Breaks And Movement (And Back It Up In Practice)

It’s not enough to say “take breaks” if your workload and culture don’t allow it.

Practical approaches include:

• encouraging micro-breaks (short, frequent pauses);
• building variety into work where possible;
• setting realistic deadlines and resourcing; and
• training managers to model good behaviour (if leaders never step away from their desk, others won’t either).

Where overtime is common, make sure you’re also across your obligations around hours and expectations. Poor ergonomics often goes hand-in-hand with fatigue risks, so it’s worth being clear on overtime arrangements and what’s reasonable in your workplace.

Step 5: Keep Notes Of What You’ve Done

Documentation isn’t about creating paperwork for the sake of it. It’s about having a clear record that you:

• identified a hazard and assessed the risk;
• took it seriously;
• implemented controls; and
• checked those controls worked.

If you ever need to show that you acted reasonably practicably, having simple records (checklists, emails, meeting notes, purchase orders for equipment) can make a big difference.

Key Takeaways

• Under HSWA, managing computer workstation ergonomics is part of your core health and safety duties as a PCBU, including preventing gradual process injuries from sustained computer work.
• Ergonomics compliance under HSWA is practical and systems-based: identify hazards, assess risks, implement controls, train your team, and review over time.
• Ergonomics risks don’t only exist in the office - you’ll usually need a reasonable approach for remote and hybrid workers too, including checklists, equipment support, and regular check-ins.
• Consultation matters: engaging with workers about discomfort, workstation fit, and workload issues is a key part of managing risks early and effectively.
• Getting workstation ergonomics wrong can lead to avoidable injuries, lost productivity, complaints, and increased legal risk - while getting it right supports retention and a healthier workplace culture.
• A simple compliance plan (minimum standards, onboarding checklist, reasonable equipment budget, break culture, and basic record-keeping) can go a long way.
