There's no “safe” lifting limit — it's about the whole task, not just the weight
Manual handling — lifting, lowering, pushing, pulling, carrying or moving a load — can cause musculoskeletal disorders (MSDs). There is no legal maximum lifting weight in New Zealand; risk depends on the whole task, not just the weight. Manage it with the hierarchy of controls, putting mechanical aids and task redesign ahead of “lift correctly” training.
There is no legal maximum lifting weight in New Zealand — and chasing a magic number misses how injuries actually happen.
WorkSafe's screening values are explicitly not “safe load limits” or acceptable weight limits; if handling occurs above them, it simply means you should do a more detailed risk assessment. A light load lifted repeatedly, in an awkward posture, or with a twist, can be more harmful than a heavier load lifted once with good technique. So the question is never just “how heavy?” — it's about the whole task.
Musculoskeletal risk comes from a combination of factors, not weight alone.
| Factor | Examples |
|---|---|
| The load | Weight, size, shape, stability, and whether it has good handles. |
| The task | How far it's moved, how often, how long, and the posture — bending, twisting, reaching, force. |
| The environment | Floor surface and space, lighting, temperature, and obstacles. |
| The person | Individual capability, and that exposure builds up over time. |
Musculoskeletal disorders can be sudden (an acute strain or even a fracture) or slow-building, where small daily loads accumulate into a chronic injury.
Work down the hierarchy of controls — and recognise that lifting-technique training, on its own, is one of the weakest controls.
The common mistake is jumping straight to “we trained them to lift properly” — useful, but it leaves a risky task in place. Redesigning or mechanising the task removes the hazard for everyone.
Where workers do manual handling, assess the risk — and WorkSafe provides tools made for the job.
A risk assessment identifies how likely an injury is, how severe it could be, and what controls to apply. WorkSafe offers three task-specific tools: the New Zealand Manual Handling Assessment Charts (NZMAC) for lifting, carrying and team handling; the New Zealand Risk Assessment of Pushing and Pulling (NZRAPP); and the New Zealand Assessment of Repetitive Tasks (NZART). Use them to pinpoint the risk factors and where to target your controls, and get specialist advice for complex or persistent problems.

No. There is no legal maximum lifting weight. WorkSafe's screening values are not safe load limits — if handling occurs above them, it just means you should do a more detailed risk assessment. The risk depends on the whole task, not the weight alone.
An MSD is an injury or condition affecting the muscles, ligaments, tendons, bones, nerves or related tissues. From manual handling, MSDs can be sudden (an acute strain or fracture) or slow-building, where repeated daily loading accumulates into a chronic injury.
The load (weight, size, shape, stability, handles), the task (distance, frequency, duration, posture and force, especially bending and twisting), the environment (floor, space, lighting, temperature), and the person and their accumulated exposure. Risk comes from the combination, not weight alone.
Use the hierarchy of controls: eliminate the handling where you can, then use mechanical aids and task or workstation redesign, then administrative controls like rotation and technique training, and PPE last. Redesigning or mechanising the task is far more effective than relying on lifting technique alone.
Carry out a risk assessment of how likely and severe an injury could be, and what controls to apply. WorkSafe provides task-specific tools: NZMAC for lifting and carrying, NZRAPP for pushing and pulling, and NZART for repetitive tasks. Seek specialist advice for complex or persistent issues.
