Manufacturing · New Zealand
Continuous-process plants run rotating 8- and 12-hour shifts including nights. Fatigue on monotonous tasks near machinery and forklifts raises the risk of injury, defects and process incidents.
Reg Watch
Regulatory change that affects how you manage fatigue in manufacturing: what has changed in the last 12 months, and what is on the way.
Recent changeFrom 9 July 2026
Applies across industries in New Zealand
The Health and Safety at Work Amendment Act 2026 became law on 9 July 2026. Your duties do not change until most of it commences on 1 April 2027, so use the lead time to evidence fatigue as a serious-harm risk.
Read the changeUpcoming changeExpected from 1 April 2027Within 12 months
From 1 April 2027 HSWA centres on 'critical risks'. Fatigue is not on the Schedule 1A list, so it counts only where it is likely to cause death or notifiable harm. Firms under 20 workers manage critical risks only; following an approved code is deemed compliance; officer duties become governance-level.
Regulatory changes checked as at 1 October 2026.
Regulation
There is no manufacturing-specific fatigue or hours-of-work rule in New Zealand. WorkSafe's manufacturing guidance covers machine guarding, noise, hazardous substances and manual handling, not shift scheduling, so rotating shifts, night work and overtime sit under the general duty to control foreseeable risks. One exception matters: a plant holding hazardous substances above the scheduled quantities is a major hazard facility, and WorkSafe expects those sites' safety management systems to include systems that reduce fatigue and manage shift work as part of fitness for work.
WorkSafeLogos identify the regulator and don’t imply endorsement.
WorkSafe New Zealand does have a manufacturing-focused resource section, but it's about physical hazards like machinery, noise, and chemical safety - not fatigue or working hours. For fatigue purposes, manufacturing employers are covered by the same general bodies as every other New Zealand industry: WorkSafe, the Human Rights Commission, Employment New Zealand, and ACC.
Manufacturers must manage fatigue as a foreseeable safety risk - rotating and night shifts, 12-hour rosters and overtime during production peaks all count - and must provide the rest and meal breaks every employee is entitled to, consider adjustments for staff with sleep or health conditions, and pay ACC levies at the rate set for their industry classification. If your site holds hazardous substances above the threshold quantities it is a major hazard facility, and its safety management system is expected to cover fitness for work, including fatigue and shift-work management. No regulation caps a manufacturing shift.
A fatigue-related incident in manufacturing is judged against the general duty, so the question is whether the risk was foreseeable and what you did about it. WorkSafe can issue improvement and prohibition notices, stop a machine or a line, and prosecute the company and its directors personally. In practice most manufacturing prosecutions start with a machine or plant failure and fatigue surfaces inside the wider systems finding, which still counts against you at sentencing. For a major hazard facility, WorkSafe can also act on the safety case itself, and courts fix compensation to the injured worker before setting any fine.
Health and Safety at Work Act 2015 maximums, unchanged since 2015 and current in August 2026: reckless exposure to a risk of death or serious injury - $3,000,000 for a company, $600,000 and up to five years' prison for an officer, $300,000 for a worker; without recklessness - $1,500,000/$300,000/$150,000; other breaches - $500,000/$100,000/$50,000. Courts fix reparation to the victim or family before the fine, often exceeding it. No manufacturing-specific scale exists.

Fatigue-critical roles
The roles where a fatigued worker is most likely to cause serious harm, the tasks that carry the risk, and why fatigue builds up in them.
| Role | Risk | High-risk tasks | Why fatigue builds |
|---|---|---|---|
Process operatorRules
| Critical risk | Running reactors, furnaces, kilns or paper machines via DCS overnight; isolations, sampling, start-up and shutdown; tapping or handling molten metal | 12 h continuous rotating rosters (e.g. 4-on/4-off day/night), 06:00/18:00 handovers, overtime to cover absences |
Machine operatorRules
| High risk | Clearing jams and changeovers on presses, extruders and conveyors; bypass and lock-out decisions at 03:00; inspection at line speed | Rotating 8 h or 12 h shifts incl. nights, repetitive paced work, overtime |
Forklift operatorRules
| High risk | Moving coils, pallets and dies with forklifts near pedestrians; loading trailers at docks; working at height on order pickers on night shift | Rotating shifts incl. nights, repetitive short cycles, congested aisles |
Maintenance engineer / electricianRules
| High risk | Isolation and lock-out, working inside machine guards, electrical fault-finding near live parts, overhead crane repairs; call-outs after a day shift | Night cover rosters, on-call call-outs with broken sleep, shutdown overtime |
Shift supervisorRules
| High risk | Accepting handover, issuing permits and authorising lock-out bypasses, deciding whether a fatigued operator stays on task, running the night alone | Rotating 12 h shifts, the only decision-maker on site overnight, overtime to cover gaps |

How the suite fits
Grades describe how strongly a product connects to an obligation. None discharges an obligation, and none carries a compliance warranty.
No New Zealand manufacturing rule names a sleep screen. Section 36(3)(g) of the Health and Safety at Work Act 2015 requires you to monitor worker health, and Sleepfit supports that for rotating shift crews. It screens; diagnosis stays with your clinicians.
About SleepfitNo New Zealand manufacturing rule names a pre-duty check. Your s 36 duty under the Health and Safety at Work Act 2015 reaches fatigue, named in s 16 as a source of hazard. A fitness-for-duty check, not a fitness-for-duty decision - the duty call stays with you.
About Fatiguefit4DutySection 36(3)(f) of the Health and Safety at Work Act 2015 requires the training needed to protect workers but does not name fatigue. Awareness eLearning supports it with fatigue and sleep content for rotating shift crews.
About Awareness eLearningYou must notify WorkSafe of a notifiable event under s 56 of the Health and Safety at Work Act 2015; no New Zealand manufacturing rule requires you to assess fatigue. A structured judgement aid, not a determination of cause.
About Was It Fatigue?No New Zealand manufacturing rule reaches sleep in new-parent households. SleepWellBaby is offered to parents of infants in your workforce as a benefit that protects their own sleep, not as a compliance step.
About SleepWellBabyRecommended bundle
Every bundle is priced on prevalence: your whole cohort gets access, and you pay for the share predicted to need each product. How pricing works.
Sleep screening and a point-of-duty check for the workers who need it most.
Proactive fatigue risk: assess, manage and train, with sleep screening underneath.
Why this pairing in New Zealand
HSWA 2015 s 36 reaches fatigue, a hazard under s 16, but names no tool. Sleepfit screens your rotating shift crews for sleep disorders, supporting s 36(3)(g) health monitoring; Fatiguefit4Duty adds a point-of-duty self-check. Prevention adds Awareness eLearning with a completion record.
