List of rail accidents in New Zealand

This list is of railway crashes in New Zealand sorted chronologically.

Level crossing and trespasser crashes are not included unless the crash was investigated by the Transport Accident Investigation Commission.

2020–present

 * 9 October 2023, Auckland. A tamper machine derailed in the Purewa Tunnel. The tamper group were travelling to a work site when they entered Purewa Tunnel where rail had been removed and the first tamping machine derailed. No injuries.
 * 17 June 2023, Penrose Station, Auckland. The Te Huia passenger train passed a red signal (SPAD – Signal Passed At Danger) and damaged points that had been set for an AT Metro train from a converging track. It stopped in the junction fouling zone, in danger of being hit side-on by the AT Metro train, which was authorised to occupy that section of track.
 * 29 January 2023, Te Puke. On East Coast Main Trunk east of Te Puke near Tauranga. the supporting embankment had been washed away by flood water. A loaded KiwiRail freight train derailed, including "at least 10" wagons and significant damage to rail infrastructure.
 * 10 January 2023, Te Puna, Bay of Plenty – two Hi-Rail vehicles were involved in a collision while undertaking track work. One vehicle occupant injured, both vehicles damaged.
 * 7 December 2022, Whangārei – a shunt train collided with a heavy road vehicle at the Fertilizer Road level crossing. Train derailed, truck trailer toppled. Train crew member seriously injured.
 * 1 June 2022, Tāmaki, Auckland – at 1:30 a.m., a shunting locomotive travelling from the Ports of Auckland to Westfield Junction with three crew members on board derailed, rolling onto its right side near the Tāmaki siding. The crew members escaped with minor injuries, and the crash closed the Eastern Line for a day.
 * 13 December 2021, near Marton – a freight train derailed north of Marton at 11:30 p.m. due to flooding of the line. Several wagons derailed and some overturned. No injuries were reported.
 * 1 September 2021, Picton – a remote-controlled shunting locomotive and a wagon fell into the sea after running off the linkspan without a ferry present. No-one was on board at the time, but the linkspan sustained some damage.
 * 17 August 2021, between Paekākāriki and Pukerua Bay – a Kapiti Line passenger train derailed due to a landslip covering the track. The carriages remained upright and all 82 passengers and three staff disembarked with no injuries.
 * 19 July 2021, Pukekohe – a Te Huia train experienced decoupling of carriages. Passengers disembarked at Pukekohe station and the service continued empty to Hamilton, where it experienced a second decoupling. No injuries reported. A report by the Transport Accident Investigation Commission identified issues with KiwiRail's safety testing and training of train staff.
 * 13 May 2021, Marton – a freight train collided with a utility truck at the Saunders Road level crossing at around 3:30 p.m. The truck caught fire as a result of the collision and the driver was killed. The line was closed for 4½ hours after the collision.
 * 10 April 2021, on board ferry Aratere, Wellington Harbour – a worker was hit by a moving wagon during shunting operations, requiring hospitalisation.
 * 11 January 2021, Invercargill – at 8:30 a.m. a coal train derailed at Wrights Bush, leaving seven wagons off the track. There were no injuries reported. The cause of the derailment is not yet known.
 * 16 September 2020, Bunnythorpe – a Palmerston North to Feilding public bus collided with a light locomotive at the Clevely Line level crossing near Bunnythorpe. The driver of the bus died at the scene and several passengers suffered minor injuries. The infrequency of the train and bus encountering each other (the train was running 15 minutes early and the bus several minutes late) and the driver concentrating on turning right off Railway Road into Clevely Line and failing to notice the crossing alarms were the likely causes of the crash.
 * 24 April 2020, between Milton and Henley – express freight Train 132 collided with a hi-rail vehicle near the Limeworks Road level crossing. The hi-rail driver was able to jump clear before impact. The vehicle suffered major damage, with minor damage to the freight train. No injuries reported.
 * 10 February 2020, Flaxton – a Coastal Pacific train carrying 95 passengers collided with a truck at Mulcocks Road level crossing, resulting in the fatality of the truck driver.

2010–2019

 * 7 December 2019, Morrinsville – a freight train collided with a car at Piako Road level crossing, resulting in the fatality of the car's two occupants. An investigation found that the car driver was likely confused by unauthorised roadworks in the area.
 * 2 July 2019, Wellington – the ninth wagon of express freight Train 268 derailed near Wellington station, resulting in a 21-hour long suspension of passenger services in and out of the station.
 * 4 April 2019, Milson, Palmerston North – express freight Train 626, pulling 37 wagons loaded with logs, derailed at a set of points. There were no injuries. Closure of the North Island Main Trunk line caused significant disruption to rail freight traffic.
 * 29 March 2019, Clinton – Three rear wagons of a freight train derailed on a crossing loop at Clinton. Excessive speed and driver distraction were found to be the main causes of the crash.
 * 9 May 2018, Britomart, Auckland – The front three cars of an inbound train derailed in the Britomart tunnel on the approach to the platforms and stopped millimetres from a concrete wall. The emergency brakes were activated and no injuries were recorded. The derailed AM class units took several days to clear. The TAIC investigation found that a manufacturing defect in a rail caused the rail to fracture.
 * 20 October 2017, Masterton – A passenger train collided with the trailer of a logging truck. The collision scattered logs across the road, but no injuries were reported.
 * 6 October 2017, Kawerau – an empty log train collided with a rubbish truck at Lambert Road level crossing, causing the truck to overturn. The truck driver was fatally injured after being thrown from the vehicle. An investigation found that the truck driver did not stop at the stop sign controlling the level crossing.
 * 29 January 2015, Morningside, Auckland – a pedestrian was struck by a train and killed at Morningside station whilst attempting to cross at a pedestrian level crossing.
 * 27 May 2014, Melling, Lower Hutt – While operating a Wellington to Melling commuter service, "Matangi" FP/FT 4472 overshot Melling station and collided with the stop block and overhead traction pole at the end of the line. Two passengers were hospitalised for minor injuries and shock. This incident should not be confused with the almost identical incident at the same station on 15 April 2013 (below).
 * 2 March 2014, Otahuhu, Auckland – An empty southbound passenger train returning to Westfield Depot derailed near Westfield Junction just before 2am. The DC locomotive and first SA carriage left the track, with the locomotive coming to rest on its side and the carriage remaining upright. The driver and train manager sustained minor injuries. The TAIC investigation identified two safety issues.
 * 27 February 2014, Rangiriri – The southbound Northern Explorer travelling from Auckland to Wellington with 108 passengers on board collided with an articulated truck at the level crossing on Te Onetea Road. The 28-year-old driver of the truck died at the scene. The TAIC investigation found two safety issues contributing to the crash.
 * 3 September 2013, Mercer – A northbound freight train derailed, leaving one wagon lying across the tracks, and two wagons blocking the Waikato Expressway. It was found that a failed wheel bearing on the 20th wagon caused the derailment.
 * 20 May 2013, Kaiwharawhara, Wellington – The rear car of a morning southbound commuter train derailed just south of Kaiwharawhara station. Split pins had not been fitted to bolts on a spring park brake cylinder when the train was serviced ten weeks earlier; the cylinder came off the car and jackknifed the nearby air reservoir tanks, pushing the car off the rails and punching a hole in the carriage floor. Four passengers suffered minor injuries.
 * 15 April 2013, Melling, Lower Hutt – at approximately 7.54 a.m., the two-car "Matangi" FP/FT 4149 failed to stop and collided with the stop block at Melling station at a speed of approximately 25 km/h. Nine passengers and two crew were on board. The KiwiRail investigation determined that driver error was the cause. This incident should not be confused with the almost identical incident at the same station on 27 May 2014 (above).
 * 9 January 2013, Glenbrook, Auckland – a freight train carrying steel from the Glenbrook Steel Mill, consisting of three locomotives and 36 wagons, derailed on the Mission Bush Branch near Glenbrook due to a wrongly configured brake control system.
 * 31 October 2011, Paekākāriki, Wellington – A 12.6-metre-long three-axle low-floor bus became stuck on the Beach Road level crossing waiting at a stop sign to turn right onto State Highway 1, and was hit by a southbound freight train. No injuries were reported. The crash was caused by the bus stopping in a position where its single driving axle was off the ground above a drain, combined with an insufficient 'stacking distance' between the level crossing and State Highway 1, meaning any vehicle over 10 metres long could not stop without encroaching either the railway line or the State Highway.
 * 1 February 2011, Ngaio, Wellington – At about 1 p.m. a Johnsonville bound suburban multiple electric unit derailed at the passing loop switch when leaving Ngaio station and ran off through a barrier fence, stopping about a metre into the station carpark. Although no one was injured, about 16 passengers were kept on board the train for around 20 minutes until the overhead electricity could be turned off, so they could disembark and continue on their journey by replacement bus. Services were replaced by buses for the afternoon but were restored by 7 p.m. A crane was used to rerail the train. KiwiRail intended to investigate the cause of the derailment.
 * 12 January 2011, Stratford – About 9:15 a.m. a New Plymouth bound freight train collided with a utility vehicle at Flint Road Level crossing, which was controlled only by stop signs, killing one person and seriously injuring two others in the vehicle. This was the fifth crash, and second fatality, at this crossing since 1992. Local residents considered the crossing was an crash waiting to happen because it was close to the highway, had limited visibility and many drivers did not stop for the crossing. They felt that barrier arms were needed. At the time of the crash, KiwiRail had been intending to install flashing lights at the crossing within the next two years, as it was high on the priority list to be upgraded.
 * 30 September 2010, Plimmerton, Wellington – At about 3:15 p.m. a mid-afternoon northbound Wellington to Paraparaumu electric multiple unit hit a landslide on the line north of Plimmerton and derailed into the path of a southbound Paraparaumu to Wellington multiple unit; two injured. The drivers of the multiple units, who happened to be father and son, both survived by flinging themselves from their respective driving compartments moments before impact. The two heavily damaged components of the Ganz-Mavag units were withdrawn from service and the undamaged components marshalled together as a new set. The TAIC investigation found that no special track inspections were made and no speed restrictions were put in place despite rainfall well above average and a site at high risk of landslide.

2000–2009

 * 23 July 2009, Maymorn, Wellington – The locomotive and first carriage of an evening northbound Wairarapa Connection derailed after hitting a mudslide at the exit to the Maoribank Tunnel; no injuries were reported, but the line was blocked for three days.
 * 1 July 2009, Newmarket West station, Auckland – an elderly vision-impaired passenger died after falling between a passenger train and the platform.
 * between 21 June 2008 and 7 May 2009, North Island Main Trunk – Three freight trains derailed in separate incidents caused by the failure and collapse of bogie side frames on wagons.
 * 12 June 2008, Bryndwr, Christchurch, Canterbury – Two freighthopping men riding on top of a southbound Main North Line freight train were knocked off after hitting an overhead footbridge and were killed.
 * 6 May 2005 part of a train (a 60-tonne crane and two wagons) repairing the bridge fell into the Nūhaka River on the Palmerston North-Gisborne Line, when Bridge 256 collapsed beneath it due to boring by teredo worms. No one was injured. Axle load limits on the line were 16.3 tonnes, but the crane weighed up to 24.1 tonnes. Due to sales of lighter cranes, following privatisation, no other was available for the job. The report also mentioned an engineering manager's opinion that the standard and frequency of ageing timber bridge inspections had fallen below desirable levels and that there were insufficient engineering staff. The bridge was reopened in July 2005.
 * 1 April 2003, Silverstream, Upper Hutt – an Upper Hutt to Wellington Express electric multiple unit fatally struck a pedestrian at the Silverstream station crossing, despite warning devices operating. The coroner found that pedestrians often ignore warning devices at this crossing and recommended that gates be installed to prevent pedestrians accidentally walking onto tracks. The first gated pedestrian railway crossing was subsequently installed at Silverstream, and served as a prototype for other busy pedestrian crossings.
 * 26 July 2002, Te Wera – Express freight train 533 bound for New Plymouth headed by DX 5045 and DC 4657 crashed after speeding when the crew had fallen asleep at around 2-3am. The train (with sleeping crew) took a curve with a 45 km/h speed restriction at around 70 km/h, and derailed, rolling down a 12 metre bank. The driver, Timothy Steffert, was crushed and died of his injuries, while the fellow operator in the cab, Daniel Brown, survived, albeit with serious leg and chest injuries. An investigation concluded that Steffert was over the legal limit of alcohol for driving at the time, and that both crew had been suffering from sleep deprivation. DX 5045 was rebuilt as DX 5520, and DC 4657 was scrapped due to its damage.
 * 12 June 2002, Silverstream, Upper Hutt – A partially-sighted passenger suffered an undisplaced leg fracture when she fell onto track ballast from the rear door of a four-car suburban Electric Multiple Unit that had been positioned too short on the platform, with the rear doors off the platform. Although the passenger was able to walk away at the time, she was hospitalised six days later when the fracture displaced. Several other stopping short incidents occurred about the same time, although without injuries. After investigating this, and other similar incidents, train operator Tranz Metro revised instructions to staff about positioning its trains on platforms and upgraded platform markings to make them more obvious to train drivers.
 * 8 January 2001 – The Southerner passenger train was involved in a level crossing crash with a cattle truck. The DC-class locomotive and two of three passenger carriages were derailed, injuring 21 passengers and forcing the destruction of 10 cattle-beasts.
 * 8 December 2000, Christchurch – Two freight trains collided in Middleton Yard after an inbound train failed to heed a danger signal, colliding with an outbound train. One engineer suffered a broken finger.

1990–1999

 * 20 October 1999, Waipahi, Otago – A northbound Main South Line express freight train collided with a stationary southbound freight train after a misunderstanding of track warrant conditions by both train drivers; one killed, one seriously injured. One of the locomotives involved (DC 4202) was written off and scrapped.
 * 21 October 1998, Rangiora, Canterbury – The northbound Coastal Pacific is unexpectedly diverted into the loop at Rangiora and collides with the rear end of the No. 2 shunt, stabled there awaiting the Coastal Pacific to overtake it. The accident occurred due to the points logic circuits reacting to an unusual shunting movement carried out by the No. 2 shunt earlier and the locomotive engineer of the Coastal Pacific having his attention diverted to looking for passengers on the Rangiora station platform to determine whether or not he would be required to stop at the station. One passenger suffers a broken nose and some members of the train crew sustain minor injuries. The TAIC made five safety recommendations.
 * 14 March 1998, Ngāruawāhia – An unsecured load on train hit a bridge while crossing the Waikato River. Six wagons were derailed with another five severely damaging the bridge. The cause was the movement of inadequately restrained stacked platform containers. The Transport Accident Investigation Commission (TAIC) identified three issues: the serviceability and uniformity of integral interlocking devices fitted to platform containers; the standards for transporting stacked platform containers internationally; and the understanding of and compliance with requirements for transporting stacked platform containers by rail. The TAIC made three safety recommendations.
 * 18 June 1997, Glen Innes railway station, Auckland – At about 11:50 a.m. an empty Silver Fern railcar returning to its depot and travelling at 80 km/h fatally collided with a pedestrian who had just disembarked from a suburban train travelling in the opposite direction at a pedestrian level crossing without warning devices. The coroner found that the pedestrian was unable to see or hear the railcar, due to the weather and noisy environment, and directed that warning devices be installed at the crossing, as a minimum. Also found that train drivers have a duty of care to pedestrians, despite having right of way, and recommended trains slow down near the station.
 * 12 November 1995 – the Northbound “Bay Express” express passenger service between Wellington and Napier, derailed at Pukehou between Waipukurau and Hastings on the Palmerston North Gisborne Line. The train was travelling at approximately 90 km/h when the locomotive, power/baggage van and an empty passenger carriage left the tracks on a right hand curve. The two rear carriages carrying passengers remained on the rails. A member of the public riding in the cab of the locomotive was fatally injured and nineteen passengers or crew suffered shock or minor injuries. The causal factor was the excessive speed of the train.
 * Late 1993, Te Kauwhata – The driver of a 660-tonne up express coal train was diverted into a loop, across the down main; the driver mistook the signal for the following signal which had a higher speed rating (50 km/h not 25 km/h). This was not the usual route; apparently intended to de-rust the loop rails!
 * 25 August 1993, Rolleston, Canterbury – The driver of a concrete mixer truck turning right off State Highway 1 failed to notice the level crossing alarms on the George Holmes Road level crossing and collided with the side of the locomotive of a southbound Southerner passenger express. The truck's mixer bowl bounced off the carriages, ripping two open; three killed (including Louise Cairns, younger sister of New Zealand Cricket Legend, Chris Cairns), seven seriously injured.
 * 19 July 1993 – Southbound train hit a Paykel Engineering Car driving over the level crossing and carrying two passengers, Andrew Lucas (driver) and his passenger. Andrew was killed instantly while his passenger was airlifted to hospital.
 * 7 August 1991, Oio, central North Island – Locomotive Engineer Graeme Peter Orange was killed and two 4000 hp EF class electric locomotives (EF30036 and 30088) were subsequently written off after striking a washout.

1980–1989

 * 12 December 1989 – Near Ward, a southbound Coastal Pacific Express passenger train was derailed while attempting to avoid an articulated truck that had come to rest on the tracks following a car versus truck collision on the adjacent state highway.
 * 7 August 1984, Edendale, Southland – An Invercargill to Balclutha shunt derailed after a section of track was washed out; one killed.
 * 18 August 1981, Waiouru, Manawatū-Whanganui – A Silver Fern railcar derailed on a curve and fell 8 m down a bank due to a missing speed restriction sign; four killed, 16 injured.
 * 19 November 1980 – A southbound EMU train derails after running into slip, north of Bean Pole Fence, on the single track section between Pukerua Bay & Paekākāriki;
 * 21 May 1980, Otira, West Coast – An eastbound coal train derailed after a 50-metre section of track was washed away during stormy weather. Driver Owen Fitzgerald was trapped in the cab of his locomotive and subsequently drowned.
 * 24 March 1980, Wellington, Wellington – During the morning peak period a Porirua to Wellington suburban multiple unit train that was signalled to enter Wellington station crashed head-on into a diesel shunter with six empty carriages from a Wairarapa train leaving the station that had somehow strayed onto the wrong line; two killed, at least 77 injured. Extensive testing found no fault with the signal system. The driver of the shunt locomotive was found not guilty of manslaughter for failing to stop for a red signal. The driver of the shunter passed what he perceived (in error) to be a yellow low-speed light; however the route selected for the shunter to the east car yards was not the usual route.

1970–1979

 * 30 November 1979 Westport-bound locomotive derailed by a slip on the Stillwater - Westport Line in the Buller Gorge.
 * October 1979, Muri railway station – Signal 3132 at Muri was over-run by a diesel-hauled goods train (diesel locos was not fitted with trips) and was involved in a minor rear-end collision with an EMU commuter train; one of two commuter trains ahead.
 * 17 October 1979, Wellington – A Porirua to Wellington suburban train (a New Zealand DM class electric multiple unit) rear-ended a stationary Taita to Wellington suburban unit, in the Thorndon yards, about 1 km short of Wellington station; at least 44 injured, five seriously. The experienced driver failed to recognise the meaning of the signal; a yellow low-speed light (Heine gives the date of the crash as 17 March 1979).
 * 19 March 1979, Matapihi, Tauranga, Bay of Plenty – A freight train went into a washout. One locomotive (DA 1436) was written off. The second locomotive DB1014 is rebuilt into DBR1200.
 * 25 May 1978, Pukerua Bay, Wellington – DA 1470, returning to Wellington light engine from Paekākāriki, derailed on a curve due to excessive speed and almost fell onto State Highway 1 below the line; two killed.
 * 23 March 1977, Newmarket, Auckland – At around 4:00 p.m. a Wellington-to-Auckland freight train collided with an Auckland-to-Helensville suburban train near the Parnell Tunnel during a widespread signal system power failure after the passenger train failed to stop at a hand-signalled junction and continued running on the wrong line; the driver of the passenger train was killed and both locomotives (DX 2639 and DA 1426) written off.
 * 21 November 1975, Silver Fern derailed in a level-crossing accident. at Feilding.
 * 24 August 1975 – RM 132 caught fire near Eketāhuna after debris collected in the inter-carriage bellows. Written off and scrapped at Eketāhuna in September 1975.
 * 20 September 1972, Wellington railway station – When the brakes failed on an electric locomotive hauling a nine car commuter train from Taita arriving on platform 4, it overran the end buffers and jumped up and hit the announcer's box. Three passengers were injured, with one hospitalised. The cause of the crash was later determined to be a brake line tap being turned off when its handle was accidentally struck by a carriage as the train negotiated the tight turnouts while entering the platform. The tap handles were modified on all affected carriages to prevent a repeat occurrence.
 * 15 February 1971, Dashwood, Marlborough – A Picton to Christchurch railcar collided with a cattle truck on a level crossing; one killed.

1960–1969

 * 23 March 1967 a Gisborne-Napier freight train and railcar crashed head on at Whakaki, injuring 16 passengers, probably due to the drivers of the DA falling asleep.
 * 19 May 1966, Dashwood Pass, Marlborough – A Christchurch to Picton mixed train (popularly named the "Cabbage Train") derailed at the southern portal of Tunnel 22, after the driver took a curve at twice the speed restriction; one killed, two seriously injured.
 * 3 November 1962, Te Kauwhata, Waikato – A northbound freight train ran a red signal and crashed into the back of a stationary freight train after the driver of the first train fell asleep at the controls; one killed. This crash sparked the introduction of vigilance devices in diesel locomotives.
 * 19 September 1961, between Pukerua Bay and Paekakariki on the North–South Junction; an EW electric locomotive hauling a freight train was derailed by a fall of rock over the abandoned No 12 tunnel, just after the passing of the Auckland Express. EW 1806 was nearly pushed over the bank to the road below, and was subsequently given an "A" grade overhaul.

1950–1959

 * 5 February 1958, Pinedale, Waikato – A Rotorua to Frankton, Hamilton freight train derailed on a curve after an air leak led to brake failure while the train was descending a 2% (1 in 50) grade; one killed, one injured.
 * 21 October 1957, Wellington, Wellington – A Plimmerton-to-Wellington suburban unit rear-ended an Upper Hutt-to-Wellington suburban unit on the approach to Wellington Station; 23 injured.
 * 23 May 1957 – A rail car hit a car on a private crossing on the Inkson farm at Omihi North Canterbury resulting in the death of Joseph and Sheila Inkson.
 * 19 February 1957 – Palmerston North shunting accident. A train reversed and a wagon was derailed resulting in a crush injury and later death of a shunter Robert Newton Smith.
 * 17 January 1956, Between National Park and Raurimu – Locomotive Jb1229 returning after banking No.227 express to National Park, derailed on a curve before entering the Spiral. Driver and fireman required hospital treatment for burns, abrasions and shock. Excessive speed likely, but the speedometer had been removed for repairs before the accident.
 * 26 October 1955, Waipuku north of Stratford. The railcar RM30 "Aotea" travelling from Wellington to New Plymouth struck a Ford Prefect car on a private level crossing which gave access to several NZR staff houses, killing three people. The driver Robert Reid (50y), his wife Moera (26y) and Arnold Cantwell were returning from the cinema at 11.09 p.m., and the railcar was travelling at about 40 mph. The private crossing had poor visibility, and the car driver did not appear to hear the railcar horn. Reid (ganger) and Cantwell (traffic assistant) were both NZR employees.
 * 3 August 1955 – On the Lyttelton Line between Lyttelton and Linwood; derailing of trucks used as buffers to push coal wagons up the ramp to the steam engine fuel depot hopper.
 * 20 July 1955 – Takapu Road, Wellington – A Paekākāriki to Wellington suburban unit, after hitting a slip on the line, derailed into the path of the other line, and was subsequently hit by a Wellington to Paekākāriki suburban unit; eight injured, one later dying of their injuries.
 * 24 December 1953, Tangiwai, Manawatū-Whanganui – Tangiwai disaster: An overnight Wellington-to-Auckland express fell into the Whangaehu River after part of the rail bridge it was crossing was swept away by a lahar from Mount Ruapehu's crater lake just minutes earlier; 151 killed.
 * 5 December 1952, Kaukapakapa, Auckland – A Maungaturoto to Auckland freight train crashed into a stationary Auckland to Opua mixed train standing at Kaukapakapa Station; one driver was killed, one fireman was seriously injured. Also, twenty head of cattle were instantly killed and another 10 later destroyed.
 * 22 April 1950, Middlemarch, Otago – At 4:25 a.m. the Cromwell-Dunedin goods train over-ran the up home signal, and collided 5 yards (4.6 m) inside the north points with the Dunedin-Cromwell goods train, locking the two Ab locomotives together.
 * 12 April 1950, Levin – A down Palmerston North- Wellington passenger train collided with the up Wellington-Auckland express passenger train at the station platform. The up train had stopped at the main platform but the down home signal was pulled off without reversing the points to bring the down train into the loop.

1940–1949

 * 25 February 1948, Seddon – Six people were killed and 63 injured when the engine tender overturned, causing the engine to also overturn, as the Picton to Christchurch express train was exiting a tightening curve. The driver admitted a "terrific error" in misjudging his speed. A board of inquiry found the driver guilty of driving at excessive speed but a jury found him not guilty of manslaughter and ascribed the accident to "inefficient administration" by assigning an acting first-grade driver, who was not familiar with the route, to drive the train.
 * 20 August 1946, Manawatū Gorge – Two engine crew presumed drowned when a goods train was derailed by a slip and fell into the Manawatu river. The body of the driver was recovered from Foxton Beach; the body of the fireman was never found.
 * 22 May 1946, Makarewa, Southland – A Tuatapere to Invercargill mixed train rear-ended a stationary workers' train that was about to leave the station; one killed, 4 injured.
 * 14 October 1945 – At Melling level crossing, Hutt Valley a car collided with a railcar, car driver seriously injured.
 * 5 January 1945, Oio near Taumarunui – The Night Limited to Wellington with 400 holiday passengers was derailed by a washout about 10.15 pm; though the engine crossed the gap, five cars were derailed and two passengers needed medical attention.
 * 8 November 1943, Haywards, Wellington – An Upper Hutt to Wellington suburban train jumped the tracks on a poorly aligned section of line that had been run down due to wartime conditions; three killed, 28 injured. The steam locomotive hauling the train, WAB 794, was repaired and is now in preservation.
 * 4 June 1943, Hyde, Otago – Hyde railway disaster: A Cromwell to Dunedin passenger train derailed on a curve due to excessive speed and the driver being intoxicated; 21 killed, 47 injured.
 * 2 October 1941, Whangaehu, near Whanganui – An AB class locomotive and 11 trucks fell into the Whangaehu River after at least one of the trucks derailed while approaching the bridge. 2 injured including the driver P. J. McLaughlin.
 * 20 May 1941, Johnsonville Branch, two units (EMUs) collided (photo).
 * 28 October 1940, Mercer, Auckland – The locomotive of an overnight Wellington to Auckland express jumped the rails on the approach to its destination; two killed, the driver & fireman; ten seriously injured. The driver was speeding over a tight (8.2 chain or 160 m radius) curve just south of Mercer.

1930–1939

 * 8 April 1938, Winchester, South Canterbury: A mixed train without engine ran away at Winchester, running as far as Temuka where it crashed at the end of a siding. One passenger was in the carriage.
 * 26 March 1938, Rātana – Fireman and six passengers killed and over 40 injured, with 13 hospitalised after a Wellington to New Plymouth excursion train derailed at about 2:18 a.m. and the engine overturned on a tight curve, at about 50 mph, rather than the 35 mph limit, after the driver misjudged his speed and location due to fog and the general lack of speed recorders in NZR steam engines.
 * 18 January 1937, near Arahura, West Coast – A Midland railcar on the Hokitika to Greymouth service was derailed at a level crossing, killing one passenger (see Midland railcar).
 * 9 October 1936, Featherston, Wellington, 1936 Wairarapa accident – A southbound Wairarapa class railcar was blown off the rails during a 130 km/h northwesterly gale; eight injured.
 * 30 August 1936, Paraparaumu – The Auckland to Wellington express derailed after hitting a slip. Three passengers taken to hospital with injuries, two discharged, but the other subsequently died.

1920–1929
