HATAITAI. WELLINGTON. Construction on, what would become, Mount Victoria Tunnel began in December 1929 and was estimated to take 15 months and cost around £132,000 (approximately $16,000,000 today). Two teams of diggers began on each side of the mountain and began tunnelling through. The initial breakthrough occurred on the 31st of May 1930, six months into construction. Construction of the tunnel continued into the next year. However, sometime in early July 1931, construction on the tunnel was halted. The workers were contacted by police to cease work on the project.  Over the next three days, over 100 police and relief workers sifted through over 2,000 tons of rock and soil from the excavation. They were searching for something, but what were they searching for, who were they searching for? Visit www.truecrimenz.com for more information on this case including sources and credits.
