The North Bank tunnel concept was a hydroelectric scheme being developed by Meridian Energy on the Waitaki River in Canterbury, New Zealand. The $993 million project was expected to produce an additional 1,100 to 1,400 gigawatt-hours (4,000 to 5,000 TJ) per annum, and take up to 260 cubic metres per second (9,200 cu ft/s) of water from Lake Waitaki. The project would have resulted in a 275 gigawatt-hours (990 TJ) per annum reduction in output from the Waitaki hydro station.[1]

Discovery of geological faultlines prompted a rethink of the project, including consideration of using a canal instead of a tunnel.[2]

Work on the project was suspended in January 2013 due to a forecast of flat demand for electricity for the next five years.[3] Resource consents for the scheme lapsed in 2016.[4]

This project is at a similar location to Project Aqua, a hydroelectric power proposal abandoned by Meridian in 2004.

Resource consent process

In December 2008, Environment Canterbury granted water use consents for this project.[5] Appeals against this decision were made by Ngāi Tahu, Ngāi Tahu Fishers People Inc, the Lower Waitaki River Management Society and Black Point farmer Garth Dovey.[6] The appeal hearings were held in the Environment Court during June and July 2009,[7] with water rights being granted in September 2009.[8]
