Discover the story behind one of New Zealand’s most tragic railway events—right here at the Ongarue Rail Disaster Memorial.
On the misty morning of 6 July 1923, tragedy struck near the quiet settlement of Ongarue in the King Country. The overnight Auckland–Wellington express train, carrying around 200 passengers, collided with a massive landslip that had engulfed the tracks following heavy rain. Hidden within the debris was a large boulder that derailed the locomotive and caused the first three carriages to telescope violently. The result was catastrophic: 17 lives were lost and 28 others were seriously injured.
This disaster marked a grim milestone—it was the first major loss of life in New Zealand’s railway history. Prior to Ongarue, fatal rail accidents had claimed only a handful of lives. The scale of devastation shocked the nation and led to significant changes in railway safety. Among the reforms were the replacement of gas lighting with electric systems in carriages to reduce fire risk, and strengthening of carriage structures to prevent telescoping in future derailments.
The Ongarue Rail Disaster remains the third deadliest rail accident in New Zealand, surpassed only by the Hyde (21 lives, 1943) and Tangiwai (151 lives, 1953) tragedies. Yet its legacy is deeply etched into the country’s transport history—not just for its sorrow, but for the resilience and reforms it inspired.
Today, the memorial stands as a solemn tribute to those who perished and those who responded with courage. It offers a wealth of historical insight, including personal stories, photographs, and accounts from survivors and rescuers. Whether you're a railway enthusiast, a history buff, or a curious traveler, this site invites you to pause, reflect, and uncover the powerful story behind the tracks.

The North Island Main Trunk Railway's Auckland to Wellington express was timetabled to leave Auckland at 7.10 pm, but was held for more than four hours. One report said that authorities were forced to await news on rain-swollen areas of the Waikato through which the express would pass, and the decision to go was not made until 10 pm. It also said that the earlier northbound express on the same route had been delayed due to landslips, and cleaning of the carriages had been necessary before it could return to Wellington as the ill-fated southbound express. The express eventually left Auckland at 11.25 pm with about 200 passengers aboard.
As the locomotive rounded a curve just south of Ongarue at about 5.52 am the next morning, it struck a landslip caused by heavy rain. Embedded in the landslip was a boulder of about 1.5 metres diameter. This boulder derailed the locomotive and threw it onto the bank of a cutting, causing the first and second carriages to telescope completely. The third carriage was partly telescoped onto the second. The postal van, between the locomotive and first carriage, was almost undamaged and none of its three postal workers were injured. About four chains (88 yards, 80 metres) of track were torn up in the accident.
Mr A. Stewart, the driver, said that he had shut off steam at the top of a rise and the train was proceeding downhill under its own weight. As it rounded a sharp bend he got a glimpse of the slip and the engine ploughed through it before he could apply brakes. Stewart thought the train could have cleared the slip safely but for the "huge boulder", which was carried along for two or three chains (44–66 yards, 40–60 metres) before the engine derailed. Stewart suffered a badly scalded arm and bruises on the head and thigh. Mr Campbell, the fireman, was badly scalded and suffered cuts to his nose and an ear.
The train's guard, H.P. Hobson, stated in an interview that the train cleared Ongarue and was then running about 25 to 30 miles per hour (42–50 km/h). About a minute and a half later, the train came to a sudden stop. Hobson sent the sleeping-car attendant back along the track to Ongarue to raise the alarm. A relief train from Taumarunui arrived within two hours after the disaster, carrying rail workers and equipment. Hobson confirmed that the presence of the boulder in the slip was primarily responsible for the telescoping of the second-class carriages, in which all the casualties occurred. He described in detail the circumstances of the wreckage and injured, and said that the first of the injured were sent to Taumarunui within two or three hours after the disaster, with the remainder arriving there shortly after noon.
