TTM plans that get approved — not sent back.

Michael Gray
Michael founded Roadcone Consultancy to write TTM plans that pass council and Waka Kotahi review the first time — no back-and-forth, no guesswork.
He's worked as a Site Traffic Management Supervisor since 2016 and holds both a Waka Kotahi NZTA Traffic Management Planner (P) qualification and Category (ABC)-NP STMS certification.

Services
Pre-planning advice
Site walk-throughs and early advice so risks and requirements are on the table before a plan is drawn.
TMP design & diagrams
Site-specific Traffic Management Plans with clear, accurate diagrams built for the job — not a template.
Council & NZTA approvals
Corridor Access Requests and approvals managed end-to-end with local councils and Waka Kotahi.
TMP review
Independent review of plans drawn up by non-qualified planners, checked against NZGTTM before they go in.
Why Roadcone
Checked against the code
Every plan is assessed against the current NZGTTM code of practice before it's submitted — not just formatted to pass at a glance.
One planner, start to finish
You deal with the person who wrote the plan — not a call centre, not a rotating account manager.
Wellington region
Council and Waka Kotahi requirements for the area are known going in, not looked up after a plan gets sent back.
Past the approval stamp
If something on site doesn't match the plan, you call the person who wrote it.
