Manual Handling NZ: Your HSWA 2015 Compliance Guide

If you’re an employer or PCBU in New Zealand, you have a legal duty under the Health and Safety at Work Act 2015 (HSWA) to manage risks from manual handling. This guide explains exactly what you need to do — in plain English — to protect your workers from musculoskeletal disorders (MSDs) and stay compliant with WorkSafe NZ expectations.

What is manual handling under NZ law?

Manual handling means any activity that requires a person to use their body to move or support a load. This includes lifting boxes, stacking shelves, moving patients in healthcare, or even repetitive hand-tool use. The risk is not just about weight — it’s about force, posture, repetition, and duration.

WorkSafe NZ does not set a fixed weight limit (e.g., 25 kg) for manual handling. Instead, the law requires a risk-based approach. You must assess the specific task, the load, the working environment, and the individual worker’s capability.

Your duty to eliminate or minimise manual handling risks

Under HSWA s.30, your duties as a PCBU include:

• Eliminate the manual handling risk — e.g., use mechanical aids like trolleys, hoists, or conveyors.
• If elimination is not reasonably practicable, minimise the risk — e.g., redesign the task, provide training, or rotate workers.

This is a hierarchy of controls. You must start at the top. If you can’t eliminate, you must minimise. You cannot simply train workers to lift “properly” and call it done — that is a lower-level control.

When must you do a manual handling risk assessment?

You must conduct a risk assessment if:

• Any manual handling task could cause injury (e.g., MSD).
• Workers report pain or discomfort.
• There is a change in the task, load, environment, or worker.
• You are introducing new equipment or processes.

WorkSafe NZ recommends using the MAC (Manual Handling Assessment Charts) tool or the NIOSH lifting equation for complex tasks. But for most workplaces, a simple risk assessment form that considers load weight, frequency, distance, posture, and grip is sufficient.

MSD prevention: What WorkSafe expects

Musculoskeletal disorders (MSDs) are the most common workplace injury in NZ. WorkSafe’s Manual Handling Guidance (updated 2025) emphasises:

• Design out manual handling where possible.
• Use mechanical aids (e.g., pallet jacks, lift tables, vacuum lifters).
• Provide information, instruction, and training — but only as a supplement to engineering controls.
• Monitor workers for early signs of MSDs (e.g., aches, stiffness).

WorkSafe also expects you to consider psychosocial factors — high work pace, low job control, and poor support increase MSD risk. This is part of the risk assessment.

Weight limits guidance: Risk-based, not fixed

There is no “legal” weight limit for manual handling in NZ. However, WorkSafe provides guidance:

• For lifting from floor to knuckle height: 16–20 kg is considered a moderate risk for most workers. Above 25 kg is high risk.
• For lifting from knuckle to shoulder height: 10–15 kg is moderate risk.
• For lifting above shoulder height: 5–10 kg is moderate risk.

These are guidelines only. You must assess the actual task. A 15 kg lift done 100 times per hour is higher risk than a 30 kg lift done once per day.

Practical steps for compliance

1. Identify all manual handling tasks in your workplace.
2. Assess the risk using a recognised tool (MAC, NIOSH, or your own).
3. Eliminate the risk — can you use a conveyor, hoist, or robot?
4. Minimise — reduce weight, improve posture, provide handles, rotate workers.
5. Train workers on safe techniques and how to report discomfort.
6. Review regularly — at least annually or after any incident.

Document everything. WorkSafe inspectors will ask for your risk assessments, training records, and control measures.

Common questions about manual handling NZ

Q: Do I need a manual handling policy?
A: Yes, it’s best practice. Your policy should outline your commitment to eliminating/minimising risks, how you assess tasks, and how workers can report concerns.

Q: Can I use a “team lift” as a control?
A: Team lifting can reduce risk, but it is not a primary control. It still requires coordination and training. WorkSafe prefers mechanical aids over team lifts.

Q: What about pregnant workers?
A: Under HSWA, you must manage risks to pregnant workers. This may mean reducing loads, changing tasks, or providing additional rest breaks. Consult with the worker and their health practitioner.
