In 1907, a young bank teller apparently lost his footing while crossing from one carriage to another, and was later found dead in the tunnel. In 1915, a railway worker was killed when accidentally stepping onto the track near the tunnel portal. In 1920, a woman fell from a train carriage near the tunnel entry, and was run over by the train, dying eight days later. In 1921, a prisoner escaped through a lavatory window while the train was making its way up the hill near the northern portal of the tunnel, and made his getaway successfully. He was recaptured three weeks later. In 1926, another prisoner escaped in the same general location from a train on which he was being brought to stand trial in Rotorua. The prisoner had been allowed to enter a lavatory without handcuffs once the train had entered the tunnel, and attacked his guard with a kick, allowing him to lock the lavatory door and subsequently smash open the window. A police search party was organised which eventually entered the tunnel to check whether the fugitive had taken refuge there. A train entered the tunnel from the CBD side while the search party was in the tunnel, and though the policemen quickly moved onto the opposing track, the concurrent appearance of a speedy train from the Newmarket side forced them to take whatever shelter they could on the floor of the tunnel or pressed against the tunnel sides. During the passage of the train, one of the policemen, Constable Begg, was struck, receiving arm, leg and head injuries from some part of the undercarriage of the train, and died subsequently in hospital. Later in 1926, a railway worker was killed within the tunnel, again having been struck by a train and sustained leg and head injuries. He died from them the next day. His death was ruled an accident, as he should not have entered the tunnel until the smoke (of a previous train) had cleared. In 1929, a naval prisoner being escorted on a train made an escape through a window while the train taking him to Wellington made its slow way up the incline leading to the tunnel on the northern side, a case very similar to the 1921 and 1926 escapes.
