CMT Group are subcontracting to HEBS for this Kiwirail project underway currently. This will be an ongoing project for more than 12 months at least. Our teams of civil construction contractors, qualified drainlayers and digger operators are installing drainage and forming sides to the new diversion. The rail diversion is bypassing the oldest tunnel on the northern line between Christchurch and Blenheim to reduce the train slowing at this point. It will give rail and road a good upgrade that is long overdue.
