Rail · New Zealand

A 24/7 railway runs on well-rested people.

Drivers, signallers and controllers work 24/7 rotating rosters with early starts and nights. A fatigue lapse can mean a signal passed at danger, a collision or a derailment.

Reg Watch

What’s changed, and what’s coming

Regulatory change that affects how you manage fatigue in rail: 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 change

Upcoming 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

Who regulates it, and what they expect

New Zealand rail has its own dedicated safety regulator and licensing system, which most industries lack - genuinely different. But the key finding: this system has no fixed rules on driver hours, shift lengths, or rest periods, unlike Australia's rail industry. The regulator requires each operator to have an approved safety plan covering risks generally, with fatigue expected to be part of it, but how is left to the company. KiwiRail runs its own fatigue program with Massey University sleep researchers, under the general safety duty every employer has.

Who regulates it

Rail in New Zealand has one extra regulator beyond the bodies every employer deals with: NZ Transport Agency Waka Kotahi, the rail safety regulator, which licenses operators, reviews safety systems, and can suspend a licence. There's also an independent investigator, the Transport Accident Investigation Commission, examining rail accidents for root causes. WorkSafe still applies to rail workers as to any industry.

Your obligations

Rail operators in New Zealand must hold a licence from the national rail safety regulator and have an approved safety plan covering how they manage risks - including, in practice, fatigue, even though it isn't spelled out in the law. They must also report and cooperate with investigations into any accidents or incidents. Beyond that, rail companies carry exactly the same fatigue, disability accommodation, rest-break and injury-compensation obligations as every other New Zealand employer - there's no special exemption or reduced standard for rail.

Consequences

Breach your licence or safety case conditions and the rail safety regulator can impose conditions, restrict or suspend your operations, or revoke the licence - a consequence with no equivalent in most industries. Separately, a fatigue-related incident is prosecuted by WorkSafe under the same general safety law and the same three-tier penalty scale that binds every employer, with reparation on top of any fine. The Transport Accident Investigation Commission can also open an independent inquiry and publish findings; its reports are no-fault and cannot prove liability, but a finding that roster design or fatigue contributed draws regulatory attention and shapes how culpability is assessed if a prosecution follows.

Penalties

There is no rail-specific fatigue fine schedule - a fatigue-caused incident is prosecuted on the same scale as any other safety failure: up to $500,000, $1.5 million or $3 million for a company by tier, and $100,000 to $600,000 for an officer personally, with reparation on top. In May 2026 KiwiRail was fined $290,000 and ordered to pay about $42,000 reparation after two workers were shocked by a live 25,000-volt line. Licence suspension carries no dollar figure.

Stories

When fatigue made the record

Published findings and prosecutions from regulators, courts and investigators in New Zealand.

Sept 2023 · New Zealand
Container terminal operator with severe sleep apnoea medically retired without specialist review; interim reinstatement ordered
- Legal
A container terminal operator employed by the national rail operator in a category 2 safety-critical role was found to have severe obstructive sleep apnoea in a 2023 sleep study, and in 2025 was assessed unfit because of poor diabetes control and untreated sleep apnoea. The employer medically retired him in 2026 without the sleep physician opinion and specialist diabetes review its own chief medical officer had said were needed. The Employment Relations Authority found a seriously arguable case of unjustified dismissal and ordered interim reinstatement, noting he could return to active duty only once cleared under the rail health standards.
Case NZ-rail-18Report an issue
May 2020 · Auckland, New Zealand
Rail operator's roster change justified by fatigue scores: Authority finds safety case not established
- Legal
The national rail operator proposed moving mechanical engineers at a locomotive servicing depot in Auckland from fixed 12-hour day or night shifts to rotating 8-hour shifts, citing fatigue analysis that rated the third and fourth night shifts as high risk. The rail union challenged the change. The Employment Relations Authority held the operator could change rosters under the collective agreement, but found it had not shown the rotating roster was safer: the fatigue tool's threshold was set for locomotive engineers, no on-the-job fatigue study was done, and no accident or near-miss data was provided.
Case NZ-rail-17Report an issue
Feb 2017 · New Zealand
Freight driver with undiagnosed sleep apnoea passes stop boards at worksite
- Safety
A train passed the warning and compulsory stop boards protecting a bridge worksite and crossed it while track workers were beneath the bridge. The Transport Accident Investigation Commission (TAIC) found the driver was likely having microsleeps, and that he was later diagnosed with a sleep disorder that affects sleep quality.
Case NZ-rail-01Report an issue
Aug 2014 · New Zealand
Fatigued protection officer clears worksite; train stops 180 m from excavator
- Safety
At 3.19am an empty passenger train came within about 180 metres of a hi-rail excavator and work group on a bridge after the rail protection officer cancelled track protection without confirming all workers had left. TAIC found the officer was likely fatigued from a high workload and long days (60+ hours in the prior week, no day fully off) and that sleep inertia impaired his judgement.
Case NZ-rail-02Report an issue
Jun 2013 · New Zealand
Train controller impaired by roster fatigue sets up near head-on collision
- Safety
A track occupation was authorised into a section a long-distance passenger train was entering; the train driver noticed the conflict and stopped. TAIC found the train controller's performance was highly likely impaired by fatigue, because his roster in the preceding weeks did not allow enough opportunity for good-quality sleep or recovery from accumulated sleep debt.
Case NZ-rail-03Report an issue
Apr 2011 · New Zealand
Mentally fatigued train controller nearly sends coal train into track vehicle
- Safety
A train controller authorised a track engineer's vehicle onto a section without verifying the location of a loaded coal train, leading to a near head-on collision. TAIC found the controller was mentally fatigued and had reduced blood glucose from insufficient food, after almost five hours without a break on a desk covering one and a half areas.
Case NZ-rail-04Report an issue
Sept 2008 · New Zealand
Controller fatigued by planned and unplanned shifts omits a train from diagram
- Safety
A train controller planned to route a freight train onto a line already occupied by a stationary freight train, risking a low-speed head-on collision. TAIC found the controller who omitted the second train was suffering fatigue from an excessive planned and unplanned roster that limited his opportunity to sleep, even though his hours closely met the minimum requirements.
Case NZ-rail-05Report an issue
May 2007 · New Zealand
Driver with undiagnosed mild sleep apnoea overruns track warrant at 4am
- Safety
An express freight train ran past a station at about 4am without track warrant authority; there was no conflicting traffic. TAIC found the driver's behaviour was consistent with extreme sleepiness and probably multiple microsleeps, after about 21 hours awake, at the circadian low, with mild obstructive sleep apnoea diagnosed after the incident.
Case NZ-rail-06Report an issue
May 2005 · New Zealand
Freight driver falls asleep and passes signal at stop at 4am
- Safety
A freight train passed a home signal at stop at about 4.10am and continued on the main line until the driver regained awareness and stopped. TAIC found the driver had fallen asleep uncontrollably because of accumulated sleep debt from poor sleep with non-work causes, compounded by too few breaks, and that his rostered and actual hours did not cause excessive sleep debt.
Case NZ-rail-07Report an issue
Feb 2005 · West Coast, New Zealand
Train controller with cumulative sleep debt sends freight train into track maintenance area
- Safety
A freight train was advanced into a track occupation where two track workers were replacing rail joints on a line in the West Coast region, after the train controller recorded the occupation incorrectly; one of the workers learned the train was close when he called train control to extend the occupation, and no one was hurt. The Transport Accident Investigation Commission found the controller's performance was probably impaired by cumulative sleep debt, circadian disruption and working near his circadian low. It found his roster excessive, the rail network owner's limits on hours and minimum time off for controllers inappropriate, and its monitoring of hours reactive.
Case NZ-rail-16Report an issue
Jan 2005 · New Zealand
Two train controllers with sleep debt issue conflicting track warrants
- Safety
On the same day, train controllers at two locations issued conflicting track warrants that put two trains on the same section; the second was caught before a head-on collision. TAIC found both controllers were probably impaired by cumulative sleep debt, one after an excessive number of late and night shifts over six weeks.
Case NZ-rail-08Report an issue
Jul 2002 · New Zealand
Fatigued driver passes signal at stop and runs 9 km before being stopped
- Safety
An express freight train passed a signal at stop, ran through reversed points and travelled about 9 km before it was stopped. TAIC identified the probable fatigue-related performance impairment of the locomotive engineer, leading to loss of situational awareness, as a safety issue.
Case NZ-rail-09Report an issue
Jul 2002 · Taranaki, New Zealand
Driver awake about 16 hours likely fell asleep; freight train derails, killing the driver
- Safety
A freight train derailed on a 45 km/h curve in Taranaki at about 1.50am after accelerating steadily for about 70 seconds; the driver was killed and the other crew member, the rail operator, was seriously injured. The Transport Accident Investigation Commission found the crew's loss of attention was consistent with having fallen asleep, that the driver had been awake for about 16 hours after a maximum of about five hours' sleep, and that the rail operator had also dozed during the trip. Alcohol consumed before duty was also listed among the causal factors.
Case NZ-rail-15Report an issue
Jan 2002 · Taranaki, New Zealand
Driver more than seven hours on shift without a break dozes off; freight train hits stationary shunt locomotive
- Safety
While berthing at a rail terminal in Taranaki at about 11.19am, an express freight train run by the national rail operator collided at low speed with a stationary wharf shunt locomotive. The Transport Accident Investigation Commission found the driver had briefly fallen asleep, most probably because he had worked continuously for more than seven hours without a meal break, partly in direct sunlight on a hot day, and was possibly carrying a sleep debt from poor-quality sleep in hot summer weather and competing demands on his rest time between shifts. It found his rostered and actual hours would not have caused excessive sleep debt.
Case NZ-rail-14Report an issue
Mar 2001 · New Zealand
Collision after driver rostered 12 night shifts in a fortnight
- Safety
Two express freight trains collided after one had stalled; both drivers were injured. TAIC found the driver of the first train probably lost attention through fatigue from accumulated sleep debt, and that his rostered 12 night shifts with one night off, about 110 hours in a fortnight, were excessive.
Case NZ-rail-10Report an issue
Dec 2000 · Canterbury, New Zealand
Driver on 11th straight shift falls asleep and passes red signal; head-on freight train collision
- Safety
A northbound freight train run by the national rail operator passed a signal at stop at about 4am and collided head-on with a departing southbound freight train in Canterbury, injuring three crew. The driver said he had been asleep for about 400 metres. The Transport Accident Investigation Commission found he was probably carrying an accumulated sleep debt on his 11th consecutive shift and 6th consecutive night shift, that his rostered and actual fortnightly hours were excessive, and that the operator had no system to monitor total fortnightly hours.
Case NZ-rail-13Report an issue
Nov 2000 · Manawatu-Whanganui, New Zealand
Milk train driver on fifth night shift falls asleep; ten tanker wagons overturn
- Safety
A milk train run by the national rail operator derailed on a curve at about 1.05am while travelling about 25 km/h over the limit, and ten loaded milk tanker wagons overturned down an embankment. The Transport Accident Investigation Commission found the driver had fallen into a microsleep at a time when sleepiness was rising steeply towards its daily peak, probably carrying an accumulated sleep debt from successive night shifts that had all run late. It found the operator's alertness management programme had reached only 35% of drivers over three years and asked the operator to research the effect of continuous night shifts and take steps against microsleeps.
Case NZ-rail-12Report an issue
Sept 2000 · Manawatu-Whanganui, New Zealand
Freight driver on excessive fortnightly hours has microsleep; train derails on steep bank
- Safety
An express freight train run by the national rail operator entered a 40 km/h curve far too fast at about 11.38pm on a steep bank in Manawatu-Whanganui; both locomotives overturned and five wagons derailed. The Transport Accident Investigation Commission found the driver had lost awareness during a microsleep, was probably carrying an accumulated sleep debt, and had worked excessive rostered and actual hours, including an extra shift he should not have been offered and a 12.3-hour shift caused by a missing relief driver. It found the operator's fatigue controls had not been fully effective: alertness training had reached only 35% of drivers, day-to-day roster changes did not follow fatigue principles, and there was no system to monitor total fortnightly hours.

How each product connects to your obligations

Grades describe how strongly a product connects to an obligation. None discharges an obligation, and none carries a compliance warranty.

Sleepfit

Supports a named obligation

Section 30(1)(k) of the Railways Act 2005 requires your safety case to set out policies ensuring rail personnel are fit for duty and not impaired by fatigue or illness. Sleepfit supports that policy. It screens; diagnosis stays with your clinicians.

About Sleepfit

Fatiguefit4Duty

Supports a named obligation

Your safety case must set out policies ensuring rail personnel are fit for duty and not impaired by fatigue (s 30(1)(k), Railways Act 2005), and s 11 requires you to comply with it. A fitness-for-duty check, not a fitness-for-duty decision - the duty call stays with you.

About Fatiguefit4Duty

Awareness eLearning

Supports a named obligation

Section 30(1)(k) of the Railways Act 2005 requires your safety case to set out policies keeping rail personnel free of fatigue impairment; it does not name training. Awareness eLearning supports that policy with fatigue and sleep content.

About Awareness eLearning

Was It Fatigue?
