Clear reporting lines
One agreed contact, your communication structure and no side-channel decisions with stakeholders.
Specialist subcontract delivery
Specialist capability. Under your lead.
Geo Mana is the crew other contractors bring in for the specialist geotechnical and difficult-access scopes. We supply skilled labour, rope-access crews and defined work-package support, fit your programme, protect your relationships and help get demanding scope off the critical path.
The partner model
Your project stays yours
We are set up to strengthen the lead contractor—not compete for the client, consultant or next package.
Site-system fit
Inductions, RAMS, programme, permits, hold points and daily records align to the controls already running on site.
Commercial discretion
Client names, partner logos, project photography and case studies stay private unless publication is explicitly approved.
Low-friction close-out
Field records, installation data and testing information are returned in a form the project team can actually use.
Where we add capacity
Specialties for difficult ground
Professional specialist labour for steep, confined, remote and access-limited workfaces.
Rope-access geotechnicians
IRATA-capable crews for workfaces beyond conventional plant, including drilling, mesh, drainage and make-safe scope.
Soil-nail and anchor drilling
Drilling and installation to the engineer's design, including shift work and labour support around established plant.
Rockfall and facing systems
Rockfall mesh, flexible facing, geocell and restraint systems installed across steep or irregular ground.
Ground anchors and testing
Anchor installation, proof-load testing, witnessing and clear test records for the project file.
Slope drainage and erosion control
Drainage outlets, surface protection and erosion systems for underslips, cut faces and exposed ground.
Urgent make-safe support
Responsive crews for active movement, fallen material and temporary protection while the permanent design is developed.
Retaining and wall remediation
Targeted repair, anchoring and access support around existing retaining systems and constrained structures.
Shotcrete and facing support
Workface preparation, reinforcement, access and specialist labour supporting designed shotcrete and facing packages.
Condition inspections and maintenance
Repeatable inspections, drainage and vegetation work, minor repairs and clear records across slope assets.
Flexible engagement
Use the part you need
The commercial model can match the gap in the delivery plan rather than forcing every job into the same package.
Specialist labour
Competent people added to an established crew, shift or plant setup under the lead contractor's supervision.
Crew and access system
A self-contained difficult-access crew with the rope, rigging and workface systems needed to reach the scope.
Defined work package
A measured package delivered to the design, agreed hold points and close-out requirements.
Representative recent scope
Proven inside bigger programmes
We have delivered under Downer NZ, Clyde Services and Tough Terrain on NZTA network sites. The scope signals below come from real Geo Mana delivery records; further project and client detail is shared privately where permission allows.
01Live industrial site
Shift-based soil-nail drilling
Specialist labour integrated into an established geotechnical team, with daily reporting and drill records across a multi-week programme.
02Main-contractor programme
1,950 m² geocell facing
A defined facing-mesh scope delivered within a wider anchor and earthworks package, with materials and interfaces coordinated by others.
03Remote underslip
Rope-access drainage installation
A three-person geotechnical rope crew deployed to install drainage where access and accommodation required regional mobilisation.
04Verification scope
Anchor proof-load testing
Independent witnessing, test records and non-conformance capture supplied back to the project team.
Asset care
Keep small defects off the critical path
Ongoing maintenance keeps remediation and stabilisation works effective: slope care, drainage and vegetation, on a plan shaped to the asset rather than a generic subscription. Start with a baseline, then set the frequency to suit the site.
- M01One-off starting point
Condition baseline
A structured first inspection covering drainage, vegetation, mesh, fixings, facing and visible ground change, with a photo-coded record and prioritised actions.
- M02Six or twelve monthly
Planned slope care
Scheduled inspection plus agreed drainage clearing, vegetation control and minor remedial work, reported back in the format your asset team needs.
- M03Triggered by event
Weather response
A pre-agreed route for post-storm inspection, escalation and make-safe advice so the right people can act quickly when conditions change.
Engineered repairs, specialist testing and emergency mobilisation are identified separately when an inspection finds work beyond the agreed maintenance scope.
Delivery discipline
Ready for serious sites
Civil Contractors New Zealand member · Amotai registered supplier · Tōtika H&S prequalification
Pre-mobilisation
Competency, access, RAMS, plant, shift and reporting expectations agreed before the crew is committed.
At the workface
Practical communication, ground-condition escalation and records maintained without slowing the production team.
At handover
Installed scope, test outcomes, exceptions and as-built information returned cleanly for close-out.
From delivery teams
The part that matters on site
Short excerpts. Partner identities are kept discreet.
“Proactive, technically skilled, and worked seamlessly alongside our team.”
“Their efficiency, professionalism and no-fuss attitude made a real impact.”
