Corridor Access Request in Christchurch, step by step

Too busy to run this yourself? Our corridor access (CAR) support team lodges and manages the whole application — with CCC, Selwyn, Waimakariri, Environment Canterbury's road managers or any road controlling authority in NZ.

Do you actually need a CAR?

A CAR is required for almost any work or occupation in the road corridor — that's the legal road, which includes the carriageway, the footpath and the grass berm, not just the sealed surface. Common triggers:

• Trenching or drilling for services (water, wastewater, fibre, power, stormwater)
• Building or altering a vehicle crossing (driveway entrance)
• Scaffolding, containers or skip bins on the berm or road
• Cranes or concrete pumps set up on the road
• Road opening for repairs, or any occupation that affects traffic or pedestrians

If your work is entirely inside private property and never touches the corridor, you don't need a CAR. The moment a machine, material, bin or pedestrian diversion crosses the boundary, you do. When in doubt, assume yes — working in the corridor without an approved CAR can get the job shut down on the spot, and "the crew was already booked" is not a defence the corridor team accepts. The permit costs a fraction of an idle crew day.

CAR vs WAP vs TMP — the three things people confuse

In plain terms: the CAR is you asking, the TMP is how you'll do it safely, the WAP is council saying yes. Most CAR applications are incomplete without a TMP — and the TMP is where most DIY applications stall. If you need one, see what a TMP costs in NZ before you budget.

Step 1: Scope the work and lock in dates

Every bounced application we've seen started life as a vague scope. Before you open any form, nail down:

• The exact location (street address, and where relative to intersections, driveways and bus stops)
• What you're doing and how deep/wide the excavation or occupation is
• Start and end dates — realistic ones, with weather and programme buffer
• Who is doing the work and who the on-site contact is

Vague scopes get bounced. "Service connection" is a scope; "open trench across footpath for a 32mm water connection, reinstated same day" is a better one.

Step 2: Get your TMP sorted

Almost every CAR that touches the carriageway, footpath or parking needs a traffic management plan prepared to the NZ Guide to Temporary Traffic Management (NZGTTM) risk-based approach. The TMP has to match the actual road environment — traffic volume, speed, pedestrians, cycle lanes — and be designed by someone qualified to do it.

Get the TMP drafted before you lodge the CAR. Lodging first and promising a TMP later is the classic way to get a "more information required" response and lose your start date.

Step 3: Lodge the CAR in MyWorksites

Christchurch City Council — like most NZ road authorities, including Auckland Transport — takes corridor access applications through MyWorksites (myworksites.co.nz), the national corridor-management system. Some authorities use the related CorridorAccess platform; the workflow is the same.

The lodgement flow:

1. Create an account (or use your company's) and start a new Corridor Access Request.
2. Drop the work location on the map. The system assigns your request to the right RCA automatically.
3. Describe the work — activity type, excavation details, dates, methodology.
4. Attach the TMP and any supporting documents (methodology, photos, service plans).
5. Declare traffic impacts — lane closures, footpath diversions, parking loss.
6. Submit. You get a reference number; the RCA's corridor team picks it up from there.

Fill every field as if the reviewer has never seen your site — because they haven't. The fields that most often cause bounces: wrong or optimistic dates, missing TMP, unclear excavation dimensions, and no traffic-impact declaration when there obviously is one.

Step 4: RCA review and conditions

The corridor team reviews the CAR against the road network: other works nearby, planned events, network condition, and whether your TMP is adequate. They can:

• Approve and move to issuing the permit
• Request more information (this is where incomplete applications stall)
• Decline if the timing or location genuinely conflicts with the network

Expect conditions on the permit: working hours, reinstatement standards, notification duties, inspection points. Read them — breaching permit conditions is how contractors end up on an RCA's problem list.

Step 5: The Works Access Permit (WAP)

The WAP is the document that lets you physically start. Check it against your programme:

• Dates — do the approved dates match your crew booking?
• Conditions — hours of work, noise windows, reinstatement spec
• Notification requirements — many permits require you to notify the RCA (and sometimes residents) a set number of days before starting

Do not let the crew start before the WAP is in hand and within its validity dates. "The CAR was approved" is not the same as "the permit is issued and current."

Step 6: During the works

• Keep the approved TMP set up as designed — the RCA or its auditors can and do inspect sites.
• If anything changes (scope, dates, traffic setup), contact the corridor team before improvising. Variations can be approved; surprises can't.
• Reinstate to the permit's standard: compaction, surface, berm condition. Photograph everything — your photos are your warranty defence two years from now.

Step 7: Work Completion Notice and the two-year warranty

When the work's done and the corridor is reinstated, you submit a Work Completion Notice through MyWorksites. The RCA may inspect the reinstatement. From acceptance, a two-year warranty period typically applies to your reinstatement work — if the trench settles or the patch fails in that window, it's yours to fix. After the warranty closes clean, the job is fully off your books.

Skipping the completion notice is a common, expensive oversight: the CAR stays open on the system and the warranty clock never properly starts.

Lead times and common bounces

How far ahead should you lodge? It depends on the RCA and the complexity:

• Straightforward works on Christchurch streets: lodge at least 10–15 working days before your start date; simple low-impact jobs can move faster, but don't bet a crew booking on it
• Complex or high-impact works (arterials, road closures): allow several weeks
• Auckland Transport: a minimum of 15 working days before work starts — genuinely plan earlier than Canterbury

The bounces we see most: no TMP attached, TMP not matching the site, dates already past, missing methodology for excavations, and CARs lodged for the wrong road (state highways are NZTA's corridor, not the local council's).

One more Christchurch-specific wrinkle: knowing whose corridor you're in. Local streets are CCC. State highways through the city — the likes of the Christchurch Northern Corridor, SH1 and SH73 sections — are NZ Transport Agency Waka Kotahi, with their own CAR process. Selwyn and Waimakariri district roads belong to those councils. MyWorksites routes your request to the right authority based on your map pin, but your lead time and reviewer change with the road — so pin accurately.

If you're lodging CARs weekly across multiple councils — CCC one week, Selwyn or Waimakariri the next — our standing support for civil contractors exists precisely for that volume problem.
