The car you planned to use may become unavailable. Perhaps it is still at the garage, another family member needs it or a business has reassigned it. Before substituting a different car for a driver journey, check the details attached to that vehicle. The same destination does not make two cars interchangeable.
Drivers on Demand (DOD) is preparing a marketplace connecting customers and businesses with verified independent drivers who drive customer-provided eligible vehicles. Auckland personal and business services are planned for 2 November 2026, subject to product alignment and readiness. Bookings are not open. DOD has not published a confirmed vehicle-substitution process, so this guide prepares questions for a future request rather than promising that a car can be changed within a booking.
Identify the replacement car precisely
Start with its registration, make, model and transmission. State which vehicle you originally proposed and which one you now want to provide. “Use the other car” leaves room for confusion, especially when a household or business has similar vehicles.
DOD's customer information asks for vehicle details, authority, roadworthiness and appropriate insurance. Treat the replacement as a vehicle that needs those questions answered in its own right. Information supplied about the first car may not describe the second.
If the replacement is not yet known, explain that uncertainty. A possible vehicle is not a complete vehicle brief, and you should not rely on a future arrangement until the actual car and service conditions are confirmed.
Recheck permission and insurance for that car
Confirm who controls the replacement and who can authorise its use by an arranged driver. A family member's car, a company car and a rental can have different permission arrangements. For a business vehicle, identify the staff member responsible for release and the person receiving it at the destination.
Consumer Protection's car-insurance guidance warns that named-driver restrictions can affect cover. An answer about one car's insurance should not be treated as confirmation for another vehicle or policy.
Ask the relevant insurer about the actual replacement car, proposed driver arrangement and intended use. Keep the response with your preparation details. This article cannot determine coverage or confirm that any policy permits a paid driver.
For a rental replacement, use the rental-car guide to frame the additional permission questions before relying on it.
Check whether the driver and vehicle still fit the request
A change from one vehicle to another can introduce a different transmission, size, seating arrangement or set of controls. Describe those differences rather than assuming that the original driver arrangement carries across.
NZTA's licence-class guidance sets out which vehicles each driver licence class covers. A replacement needs to fit the driver's applicable licence entitlements as well as the final DOD eligibility and matching requirements. Do not infer eligibility just from a similar appearance or the word “car”.
Ask how the published service process will assess the change and whether the proposed driver can still undertake the journey. Do not assume that editing a registration, messaging a driver or handing over different keys would by itself approve the substitution.
Revisit passengers, belongings and handover
Check the actual seating and storage arrangement for everyone travelling. If the replacement has less room, the original passenger and luggage plan may need to change. Account for any child restraint or mobility equipment before deciding that the new car is suitable.
Use the luggage guide for the stowage questions. Describe any change in passenger or equipment needs through the final service process; a different vehicle should not silently change what the driver is being asked to do.
Then update the practical handover. Where is the replacement parked? Who holds its keys? Does the receiving person know which car to expect? The business handover guide helps organise those contacts.
Ask about the booking outcome before relying on the change
When bookings open, check the published amendment process and any terms shown for the actual request. Ask whether the change can be accommodated, whether another request is needed and what happens to the original arrangement. This guide does not establish amendment rights, charges, response times or a guaranteed replacement driver.
If the need for a different car arises because the first has a problem at pickup, use the vehicle-concern guide. Offering another car does not resolve that concern or establish approval of the alternative.
An illustrative enquiry could say: “The hatchback we originally proposed is unavailable. We would like to use our automatic sedan instead. We can provide its registration, authority and insurance details. Please explain what needs to be checked before we can rely on that arrangement.” This is a planning example, not a completed DOD amendment.
A replacement-vehicle checklist
| Detail | What to confirm again |
|---|---|
| Identity | Registration, make, model and transmission |
| Permission | Authority to provide this particular vehicle |
| Insurance | Applicable policy and proposed driver/use conditions |
| Driver suitability | Relevant licence entitlements and final service matching |
| People and belongings | Seating, restraints, luggage and equipment |
| Handover | Pickup, key holder and receiving contact |
| Request outcome | Approved process and what happens to the original plan |
During prelaunch, use Contact DOD for general enquiries about a future journey. Enquiring or joining the launch list does not approve a replacement vehicle or reserve a driver. For travel before bookings open, arrange a suitable option that is already available.
