Oil & Gas · New Zealand
Offshore and remote crews work 12-hour shifts on multi-week rotations, often swinging between days and nights, in shared quarters. Fatigue in major-hazard operations can be catastrophic.
Reg Watch
Regulatory change that affects how you manage fatigue in oil & gas: 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's oil and gas sector carries real extra regulation: operators must prepare a detailed safety case addressing major-accident hazards and get it accepted by WorkSafe's specialist High Hazards Unit before operating, plus offshore installations need certified fitness approvals. But none of this targets fatigue specifically - it's all process and physical safety. Fatigue for extended shifts and offshore rotations is still managed only under the general workplace safety duty, same as every other industry.
WorkSafeLogos identify the regulator and don’t imply endorsement.
WorkSafe New Zealand, through its specialist High Hazards Unit, is the primary safety regulator for petroleum sites. New Zealand Petroleum and Minerals issues exploration and extraction permits but doesn't regulate worker safety, and the Environmental Protection Authority covers hazardous substances and offshore environmental effects. Standard employment, human rights and ACC bodies apply as they do to any employer.
Operators must prepare a safety case addressing major-accident hazards and get it accepted by WorkSafe's High Hazards Unit before starting operations, and offshore installations need Certificates of Fitness plus accommodation and emergency-refuge standards. Beyond that, companies carry the same general fatigue-management, rest-break, disability-accommodation and injury-compensation duties as any other New Zealand employer - there's no fatigue-specific rule, even for offshore rotation work.
You cannot operate without a safety case WorkSafe has accepted, so the first consequence of a weak one is commercial: WorkSafe can decline to accept it or require it to be revised before work proceeds, and offshore installations need a current certificate of fitness. Inspectors review the case and visit the site, so a gap between what the document says about staffing and shift arrangements and what actually happens on the installation tends to be found. If someone is seriously hurt, WorkSafe prosecutes under the general safety Act, directors and officers can be charged personally alongside the company, and the court fixes compensation to the victim before it sets 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. Petroleum work has no separate scale.

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 |
|---|---|---|---|
Control room operator (Taranaki production station)Rules
| Critical risk | Monitoring the DCS through the night, alarm handling, start-ups and shutdowns, responding to process upsets and gas detection; shift handover | 12 h shifts with a day/night swing mid-hitch (e.g. 14/14, 2/3), 06:00/18:00 handovers, low-stimulation night vigilance |
Driller / roughneckRules
| Critical risk | Tripping pipe and making connections on the rig floor, kick detection and well control, monkey-board work at height, handling suspended tubulars | 12 h tours incl. nights on 14/14 or 21/21 hitches, crew changes after long travel, heavy physical load |
Tanker driver (fuel / condensate)Rules
| Critical risk | Driving water, sand, crude and fuel tankers on lease roads and highways at night; loading and unloading flammable product; well-site waiting time | Long on-duty days with waiting time, night driving, remote rural routes, rotational schedules |
Crane operator (offshore platform)Rules
| High risk | Lifting containers and drill pipe between supply vessel and deck in swell, blind lifts on radio, lifts during turnarounds near live plant | 12 h shifts on 2/3 or 14/14 rotations, night lifts, weather-window pressure |
Shutdown maintenance technicianRules
| High risk | Isolating, purging and issuing permits-to-work; confined-space entry and hot work; reinstating plant after long consecutive days of turnaround work | Turnaround blocks of 12 h x 14-28 consecutive days incl. nights, contractor surge crews, schedule pressure |
Stories
Published findings and prosecutions from regulators, courts and investigators in New Zealand.
May 2015 · Taranaki, New Zealand
A drilling contractor working on petroleum, gas and geothermal rigs ordered crews to live in camp during 14-day hitches and limited time away from camp between 12.5-hour shifts, aiming to make sure workers got at least 7 hours' sleep. The union challenged the directive. The Employment Relations Authority found no evidence that the curfew would actually achieve the sleep objective, noted the employer accepted its shift pattern may contribute to fatigue, and said that if the work pattern creates the hazard, the work pattern is what should change; the directive was declared unenforceable.

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 petroleum rule names a sleep screen or a fatigue duty. Your s 36(3)(g) duty to monitor worker health applies offshore and onshore, and Sleepfit supports it. It screens; diagnosis stays with your clinicians.
About SleepfitNo New Zealand petroleum rule names a pre-duty fatigue check. Your s 36 duty under the Health and Safety at Work Act 2015 reaches fatigue, which s 16 names as a source of hazard. A fitness-for-duty check, not a fitness-for-duty decision - the duty call stays with you.
About Fatiguefit4DutyNo New Zealand petroleum rule names fatigue training. Section 36(3)(f) of the Health and Safety at Work Act 2015 requires the training needed to protect workers, and Awareness eLearning supports it with fatigue content for rotating crews.
About Awareness eLearningYou must notify WorkSafe of a notifiable event under s 56 of the Health and Safety at Work Act 2015; no petroleum rule requires you to assess fatigue. Was It Fatigue? supports your own review. A structured judgement aid, not a determination of cause.
About Was It Fatigue?No New Zealand oil and gas rule reaches sleep in new-parent households. SleepWellBaby is offered to parents of infants in your workforce, including those on rotation, as a benefit rather than 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.
Proactive fatigue risk: assess, manage and train, with sleep screening underneath.
Assess, manage, investigate: from the Census to the point of duty to the post-incident review.
Why this pairing in New Zealand
No petroleum rule names a fatigue tool, so HSWA 2015 s 36 applies offshore and onshore. Sleepfit screens rotating crews, Fatiguefit4Duty adds a point-of-duty check and Awareness eLearning trains with a record. Fatigue Lifecycle adds review of notifiable events.
