Takaka Hill Works Completed

Client : NZTA

Head Contractor : Fulton Hogan

Six months of hard work on Takaka Hill are now complete!

Following the major storm event in 2025, Ground Anchor Systems was engaged by Fulton Hogan and NZTA to deliver the anchored shotcrete and horizontal drainage works across multiple sites on Takaka Hill. The slips caused significant ground movement, elevated groundwater pressures, and a loss of road width, requiring a fast, coordinated response to stabilise the hillside, dewater the slope, and keep this vital State Highway route open.

Ground Anchor Systems, working alongside Fulton Hogan and Stantec, has delivered all site works on this critical project strengthening the only route between Golden Bay and Nelson.

Across the programme we installed 1000m of ground anchors, 350m² of shotcrete, 1700m of horizontal drains, and 2000m² of coconut matting, all while keeping traffic moving through the site.

This was a huge effort from the crew and a project we’re proud to deliver, improving long term stability and resilience on this vital corridor. Even better, it’s been great to see the works performing exactly as intended. Effective, stable, and already proving their value to the route.


A big thank you to all collaborators for their teamwork and commitment throughout this project.

Head Contractor : Edridge Contracting

Recently Ground Anchor Systems was engaged by Edridge Contracting to complete some light scaling works on the 17km Northbank site in Marlborough.  The brief was to complete light scaling on the 15m high rock face directly above the road and also work through the vegetated north end of site to remove any lager rocks that posed a risk to the traffic below. 

Over two days our crew safely removed a significant amount of material, improving slope stability and reducing hazards along this key stretch of road.

Head Contractor : Downer

Keeping the only road into Duncan Bay open is critical for the Marlborough Sounds community.  

We’re at Tennyson Inlet Road completing stage two of the temporary works: drilling and grouting a row of 45‑degree soil nails into the cut face, followed by bitumen cloth, SE62 mesh and walers to secure the slope.  

With this stage wrapped, Downer can safely cut the face again, and we’ll be back next week to install the final four‑metre temporary nails before assisting with the permanent anchors into the block wall.
