The damage caused by the 7.8 magnitude November 2016 Kaikoura earthquake to the Main North Line (MNL) railway (and SH1 along the east coast of the South Island) was unprecedented in New Zealand.

Kaikoura Earthworks
Date: 2017 - present
Client: NCTIR
Project value: $5m ongoing

Geotech were engaged by the North Canterbury Transport Infrastructure Recovery(NCTIR)to assist with restoring road access to Kaikoura after the 7.8 magnitude earthquake in November 2016. Geotech staff have been working on sections of the narrow coastal corridor of SH1 south of Kaikoura, with additional crews working north of Kaikoura. Works have predominantly been made up of clearing landslides. Work is not straightforward due to the fractured cliff faces being unstable. Damaged slopes continue to release rock and material, and weather events and continuing seismic activity have presented ongoing challenges throughout the contract, including additional land and mud slides during bad weather events.
