Mining & Resources · New Zealand
Crews work 12-hour rotating shifts, nights and FIFO or DIDO rosters, then often drive long distances home. Fatigue around heavy mobile plant and processing hazards can be fatal.
Reg Watch
Regulatory change that affects how you manage fatigue in mining & resources: 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'. Hazards under the mining and petroleum regulations are listed in Schedule 1A, so your regulated risks sit in the critical tier; fatigue elsewhere counts only where likely to cause death or notifiable harm. Following an approved code is deemed compliance; officer duties become governance-level.
Regulatory changes checked as at 1 October 2026.
Regulation
New Zealand mining is one of the few sectors where fatigue is named in regulation, though the duty is narrower than it is often described. Under the Mining Operations and Quarrying Operations Regulations 2016, a mining operation that has identified a principal hazard capable of long-term harm to worker health must hold a principal control plan for worker health, and that plan must include strategies for dealing with fatigue. Quarries and alluvial mines are not required to hold one. No regulation sets a maximum shift length or a minimum rest period for mine workers.
WorkSafeLogos identify the regulator and don’t imply endorsement.
New Zealand mining and quarrying operators are regulated by WorkSafe New Zealand under both the general safety law and a dedicated set of mining and quarrying regulations introduced after the 2010 Pike River mine disaster. WorkSafe runs a specialist extractives team that oversees this sector specifically, on top of the general bodies that apply to every industry.
If you run a mining operation and have identified a principal hazard that can cause long-term harm to worker health, your principal control plan for worker health must treat hours of work and fatigue as hazards to monitor and control, and must set out strategies for fatigue and for drug and alcohol use in proportion to the hazards on site. WorkSafe's extractives guidance expects that assessment to take in travel time to and from remote sites and shift patterns, not just time on the job. Quarrying and alluvial operations are not required to hold that plan, but every operator still has to manage fatigue as a foreseeable risk.
WorkSafe's extractives inspectors can call for your health and safety management system, principal hazard management plans and control plans at any time, and can issue improvement and prohibition notices that stop work until fatigue controls are in place. If a worker is hurt or killed and the fatigue strategies the plan was meant to contain are missing or were never used, that is evidence in a prosecution rather than a paperwork problem, because a specific named requirement has been failed and not only a general duty. Directors, officers and the site senior executive can be charged personally alongside the company, and convictions are published.
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. The mining rules add no separate scale.
On the record
No New Zealand court, coroner, investigator or regulator has published a finding linking fatigue to an incident in mining. The duty to manage fatigue still sits within the primary duty of care under the Health and Safety at Work Act 2015.

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 |
|---|---|---|---|
Dump truck operatorRules
| Critical risk | Driving a 200-300 t haul truck through the 02:00-06:00 window; ramp descents, dumping at crest/edge, intersections with light vehicles; monotony between loads | 12 h day/night rotations, 4+ consecutive nights, FIFO/DIDO swings (e.g. 8/6, 14/7) and a long drive home after the last night |
Underground loader operatorRules
| Critical risk | Operating loaders (LHD/bogger), continuous miners or shuttle cars in confined headings; tele-remote bogging at the stope brow; vehicle-pedestrian interaction in low light | 12 h rotating day/night underground with no daylight cues, heat, FIFO swings, long travel in and out of the decline |
Winding engine operatorRules
| Critical risk | Driving the shaft winder carrying people and rock; signalling, speed and overwind control; long low-stimulus monitoring through the night | 8-12 h shifts incl. nights, long low-stimulus monitoring, often alone in the winder house |
Mine deputyRules
| Critical risk | Pre-shift and in-shift inspection for gas, ground and ventilation; deciding whether crews may enter; gas testing and reporting at the end of a night shift | 12 h rotating shifts with inspections timed at the start of each shift, including the 04:00-06:00 low |
ShotfirerRules
| High risk | Charging and tying-in blast holes, misfire handling, clearing and guarding the blast area, firing near shift change; re-entry decisions after the blast | Blasting at shift change or end of night shift, time pressure to fire on schedule, 12 h rotations |
Mine maintenance fitter / electricianRules
| High risk | Isolation and lock-out of HV and mobile plant, work under raised loads, haul truck tyre changes, conveyor repairs during night shutdowns | 12 h rotating shifts, night shutdowns and call-outs, overtime during planned shutdowns |
How the suite fits
Grades describe how strongly a product connects to an obligation. None discharges an obligation, and none carries a compliance warranty.
Regulation 108 of the Mining Operations and Quarrying Operations Regulations 2016 requires your worker health control plan to monitor and control hours of work and fatigue. It names no screen. Sleepfit supports that plan. It screens; diagnosis stays with your clinicians.
Assessed by reference to Australian regulation.
About SleepfitYour worker health control plan under regulation 108 of the Mining Operations and Quarrying Operations Regulations 2016 must provide strategies to deal with fatigue. A fitness-for-duty check, not a fitness-for-duty decision - the duty call stays with you.
About Fatiguefit4DutyRegulation 108 of the Mining Operations and Quarrying Operations Regulations 2016 requires strategies to deal with fatigue in your worker health control plan; it does not name training. Awareness eLearning supports those strategies.
About Awareness eLearningThe mining regulations name no fatigue assessment after an event, and s 56 of the Health and Safety at Work Act 2015 requires notification without naming a cause. Was It Fatigue? supports your review. A structured judgement aid, not a determination of cause.
About Was It Fatigue?No New Zealand mining rule reaches sleep in new-parent households; regulation 108 concerns mine workers' health at work. SleepWellBaby is offered to parents of infants in your workforce as a benefit.
