The Kaimai Tunnel is a railway tunnel through the Kaimai Range in the North Island of New Zealand. Since it was opened in 1978, it has held the title of longest tunnel, at 8.879 kilometres (5.517 mi), in New Zealand,[1] assuming this distinction from the previous title holder, the Rimutaka Tunnel.[2] It is part of the Kaimai Deviation, which was constructed to bypass the old route of the East Coast Main Trunk Railway through the Karangahake Gorge (part of which has been preserved as the Goldfields Railway).

  2. ^ Stott 1978, p. 4"After considerable study it was decided that the best course of action would be to construct a railway tunnel under the Kaimai Range, a tunnel which would become not only the longest of its kind in New Zealand but also the longest in the Southern Hemisphere."
