Aviation · New Zealand
Pilots, cabin crew and controllers work early starts, nights and time-zone changes. Duty limits cap hours, not sleep obtained, and a fatigue lapse in flight or on the ground can be catastrophic.
Reg Watch
Regulatory change that affects how you manage fatigue in aviation: 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 likely to cause death or notifiable harm. Where the Civil Aviation Act manages the same risk, complying with it can satisfy the matching HSWA duty. Small firms (under 20 workers) manage critical risks only.
Regulatory changes checked as at 1 October 2026.
Regulation
Aviation is one of the few New Zealand industries with government-mandated fatigue rules beyond general safety law, and they are built differently from Australian or American ones. Rather than one national duty-time table, each operator designs its own flight and duty time scheme covering rest before flight, time-zone acclimatisation, night operations, standby and reserve duty and days off, and the Director of Civil Aviation must approve it first. Fixed cumulative caps sit on top, and they differ by operation - aeroplane and helicopter operators work to different numbers. Every flight crew member also has a personal duty to refuse duty when fatigued.
CAA
WorkSafeLogos identify the regulator and don’t imply endorsement.
The Civil Aviation Authority sets and enforces flight crew fatigue rules and is also the designated health and safety regulator for work preparing an aircraft for imminent flight, work on board an aircraft in operation, and aircraft as workplaces. WorkSafe New Zealand regulates the rest of your operation - hangars, ground handling, offices - so two regulators cover fatigue across one workforce.
You must design a flight and duty time scheme covering rest before flight, time-zone acclimatisation, night operations, standby and reserve duty and days off, and have the Director of Civil Aviation approve it - you cannot self-certify your own limits. Fixed caps apply on top. For large and medium aeroplane operations under Rule Parts 121 and 125, no flight crew member may exceed 100 flight hours in any 28 consecutive days or 1,000 hours in any 365. Helicopter and small aeroplane operators under Part 135 work to different limits - 160 hours in any 30 days, plus minimum days free of duty. Flight and duty records must be kept 12 months.
The Civil Aviation Authority enforces the fatigue rules through certificate action rather than a published fine tariff: it can require corrective action, impose conditions, and suspend or revoke your air operator certificate or an individual crew licence. For an operator, that is existential. Because the Authority is also the designated health and safety regulator for work on aircraft in operation, the same failure can be pursued under general safety law with its full three-tier penalty scale and reparation orders, while WorkSafe covers the rest of your operation. Flight crew carry a personal duty to stand down, so a scheme that pressures crew to fly fatigued creates exposure at both ends.
There is no published fine tariff for a flight and duty time breach - the regulator's main lever is certificate action, and a suspended or revoked air operator certificate costs more than any fine. Where the same failure is pursued under general safety law, the ceilings for a company are $500,000, $1.5 million and $3 million across the three offence tiers, and $100,000 to $600,000 for an officer, with up to 5 years' imprisonment at the top tier and reparation on top.

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 |
|---|---|---|---|
Airline pilot (captain / first officer)Rules
| Critical risk | Flying approaches and landings after extended duty or through the window of circadian low; multi-sector days; managing non-normal events at the end of a duty | Early report times, overnight flights, time-zone crossing, reserve and standby, short-notice roster changes |
Air traffic controller (Airways New Zealand)Rules
| Critical risk | Separating traffic on low-workload overnight positions, sometimes single-person; handling the morning surge at the end of a night shift; coordination and handovers | 24/7 rotating shifts with quick returns, night shifts, single-person night operations at some units |
Licensed aircraft maintenance engineer (LAME)Rules
| Critical risk | Night-shift line and base maintenance; flight-control rigging, torque and duplicate-inspection tasks; certifying release to service at the end of a long shift | Night shifts to meet first-wave departures, AOG overtime, 12 h shifts, rotating rosters |
Air ambulance / charter pilot (Part 135)Rules
| Critical risk | Single-pilot night aeromedical or charter flights after an on-call call-out; helicopter landings at unlit sites; IFR approaches at the end of duty | On-call and standby with night call-outs, single-pilot operations, remote bases |
Flight attendant / cabin crewRules
| High risk | Safety and emergency duties, evacuation command and in-flight incident response after long or overnight duties; door arming and cross-checks | Early starts, overnight and long-haul duties, multi-sector days, time-zone crossing, standby |
Ground handler / ramp operatorRules
| High risk | Aircraft pushback and towing; baggage tug driving and loading near engines and stairs; refuelling hook-ups on overnight turns | Split shifts and starts from 04:00, night freight turns, overtime in peaks, outdoor work |

How the suite fits
Grades describe how strongly a product connects to an obligation. None discharges an obligation, and none carries a compliance warranty.
Rule 121.803(b) bars you from letting a crew member fly if you have reason to believe fatigue is likely. CAA medical examiners refer pilots scoring 3 or more on STOP-Bang to a sleep physician; Sleepfit uses the same questionnaire. It screens; diagnosis stays with your clinicians.
About SleepfitRule 121.803(b) bars you from letting a crew member fly if you know or have reason to believe they are, or are likely to be, fatigued; rule 121.805 puts a matching duty on crew. A fitness-for-duty check, not a fitness-for-duty decision - the duty call stays with you.
About Fatiguefit4DutyPart 121 Subpart K sets flight and duty schemes and a fatigue duty but names no fatigue training. Awareness eLearning supports your general training duty under s 36(3)(f) of the Health and Safety at Work Act 2015 with fatigue content.
About Awareness eLearningRule 12.59 requires you to investigate an incident and establish its causes, but names no fatigue assessment. Was It Fatigue? supports that investigation with a structured fatigue account. A structured judgement aid, not a determination of cause.
About Was It Fatigue?No New Zealand aviation rule reaches sleep in new-parent households; the Part 121 fatigue rules concern crew on duty. SleepWellBaby is offered to parents of infants in your workforce as a benefit.

Why this pairing in New Zealand
CAR 121.803(b) bars you from letting a crew member fly if fatigue is likely; Fatiguefit4Duty supports that call with a check. CAA examiners use STOP-Bang, as Sleepfit does. Awareness eLearning trains under s 36(3)(f). Fatigue Lifecycle adds Was It Fatigue? for rule 12.59 investigations.
