Specialist subcontract delivery
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
We are set up to strengthen the lead contractor—not compete for the client, consultant or next package.
One agreed contact, your communication structure and no side-channel decisions with stakeholders.
Inductions, RAMS, programme, permits, hold points and daily records align to the controls already running on site.
Client names, partner logos, project photography and case studies stay private unless publication is explicitly approved.
Field records, installation data and testing information are returned in a form the project team can actually use.
Where we add capacity
Professional specialist labour for steep, confined, remote and access-limited workfaces.
IRATA-capable crews for workfaces beyond conventional plant, including drilling, mesh, drainage and make-safe scope.
Drilling and installation to the engineer's design, including shift work and labour support around established plant.
Rockfall mesh, flexible facing, geocell and restraint systems installed across steep or irregular ground.
Anchor installation, proof-load testing, witnessing and clear test records for the project file.
Drainage outlets, surface protection and erosion systems for underslips, cut faces and exposed ground.
Responsive crews for active movement, fallen material and temporary protection while the permanent design is developed.
Targeted repair, anchoring and access support around existing retaining systems and constrained structures.
Workface preparation, reinforcement, access and specialist labour supporting designed shotcrete and facing packages.
Repeatable inspections, drainage and vegetation work, minor repairs and clear records across slope assets.
Flexible engagement
The commercial model can match the gap in the delivery plan rather than forcing every job into the same package.
Competent people added to an established crew, shift or plant setup under the lead contractor's supervision.
A self-contained difficult-access crew with the rope, rigging and workface systems needed to reach the scope.
A measured package delivered to the design, agreed hold points and close-out requirements.
Representative recent scope
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.
Specialist labour integrated into an established geotechnical team, with daily reporting and drill records across a multi-week programme.
A defined facing-mesh scope delivered within a wider anchor and earthworks package, with materials and interfaces coordinated by others.
A three-person geotechnical rope crew deployed to install drainage where access and accommodation required regional mobilisation.
Independent witnessing, test records and non-conformance capture supplied back to the project team.

Asset care
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.
A structured first inspection covering drainage, vegetation, mesh, fixings, facing and visible ground change, with a photo-coded record and prioritised actions.
Scheduled inspection plus agreed drainage clearing, vegetation control and minor remedial work, reported back in the format your asset team needs.
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
Civil Contractors New Zealand member · Amotai registered supplier · Tōtika H&S prequalification
Competency, access, RAMS, plant, shift and reporting expectations agreed before the crew is committed.
Practical communication, ground-condition escalation and records maintained without slowing the production team.
Installed scope, test outcomes, exceptions and as-built information returned cleanly for close-out.
