Of everything that follows a Parkinson’s diagnosis, the licence is often the thing people worry about first and ask about last. The fear is that mentioning it to a doctor ends it. What actually happens is a process, and the most common outcome of that process is not losing the licence.

New Zealand handles it as a medical review of fitness to driveA process, separate from routine licence renewal, for assessing whether a medical condition affects someone's fitness to drive. The outcome may be continuing to drive with conditions attached, or losing the licence.Learn more, run by NZ Transport Agency Waka Kotahi with your health practitioner at the centre of it. Checked in August 2026.

The declaration you already sign

NZ Transport Agency’s baseline rule:

You have to confirm that you are medically fit each time you apply for, renew or replace your driver licence. This may simply involve signing the declaration on the licence application form. But you may need to present a medical or eyesight certificate.

The declaration asks about specific conditions — diabetes, strokes, “locomotive joint or limb problems”, “seizures, fits, convulsions, epilepsy”, “cognitive impairment”, “visual disturbances” — and then closes with a catch-all:

Any other condition that may affect your ability to drive safely, including fatigue, disabilities and conditions such as dementia.

Parkinson's is not named in that list, and it does not need to be. It falls squarely under the catch-all, and fatigue is specifically named — which matters, because fatigue is one of the parts of Parkinson's people are least likely to think of as a driving issue.

When a medical certificate is required

You will need one when:

The certificate itself:

  • “A New Zealand-registered health practitioner must complete your medical certificate.” That can be “your usual doctor (GP), a registered nurse or nurse practitioner, or a specialist if appropriate.”
  • It “must be no more than 60 days old”.
  • It will “either state that you are safe to drive, or set out the conditions under which you can drive safely.”
  • “You are responsible for the cost of getting your certificate. The cost varies between medical centres.”

The 60-day rule is the practical trap. Getting a certificate months in advance of a renewal wastes the appointment and the fee. Work backwards from the renewal date.

The occupational therapy assessment: what it actually tests

A road curving through open country

If your health practitioner is not satisfied about your fitness to drive, they can refer you for a driving assessment with an occupational therapist. NZ Transport Agency describes it as “a medical check, requested by your health practitioner or Waka Kotahi.” It has two parts.

The off-road assessment, up to two hours in the therapist’s office, is “a thorough check of”:

What is checkedWhy it matters in Parkinson’s
Vision (basic screening)Contrast and visual processing can change
Physical functions — “range of movement, strength, sensation and coordination”The obvious one, and usually the one people prepare for
JudgementNot a motor symptom, and easily overlooked
MemoryRoute-finding and instruction-following
Directional orientationGetting lost is a driving safety issue, not just an inconvenience
“Movement and decision making times”Reaction time, which slows before most people notice
“How your mind understands what you see”Visual processing, which can be affected independently of eyesight
Knowledge of road rules and signsStraightforward, and worth revising
Six of those eight are not about tremor or stiffness. If you have been preparing by thinking about whether you can still turn the wheel, you have been preparing for a quarter of the assessment. Reaction time, judgement and visual processing are the bulk of it.

The on-road assessment follows, “approximately 40-60 minutes of driving”, accompanied by the occupational therapist and sometimes a specially trained driving instructor. It covers “driving on both the open road and urban roads”, “driving through controlled and uncontrolled intersections”, “parking” and “manoeuvring”.

Note one procedural detail that catches people: “If you don’t have a current driver licence, make your assessor aware of this at least one week before the assessment, so they can get one on your behalf. Without a temporary licence, you’ll be unable to sit the on-road assessment.”

Afterwards, “the occupational therapist will write a report outlining their observations and providing a professional recommendation. This report will be sent back to the health practitioner who asked for you to be assessed.” The practitioner then decides on the certificate. So the therapist recommends; your doctor decides.

Preparing for it, with a fluctuating condition

This is the part that no guidance covers, and it is the one that matters most with Parkinson’s.

The outcomes, including the ones that are not a ban

If NZ Transport Agency runs a medical review, the process is: “We receive information about your medical condition. We review that information against safety legislation and the medical guidelines for fitness to drive. We let you know if you can continue to drive or not.”

There are four possible outcomes, and only one of them is losing the licence.

OutcomeWhat it means
You continue driving“If we decide that you’re medically fit to continue driving, we’ll let you know. There’s nothing else you need to do”
You continue with conditionsConditions are placed on the licence and you must follow them. An example given is a recommendation that you “only drive vehicles with an automatic transmission”
You continue with regular medical reports“We may require you to send us regular medical reports in future”. A reminder comes “about five weeks before your next medical report is due”
Part or all of the licence is revokedYou may be found no longer fit for certain classes, or to drive at all. A letter explains it
The third outcome contains a hard edge worth remembering: “If you don't send your medical report to us on time, we will revoke part or all of your driver licence.” A licence lost to a missed form is exactly as lost as one lost on medical grounds, and considerably more annoying to get back.

And there is a right of appeal: “If we’ve given you driver licence conditions or we’ve revoked part or all of your driver licence, you do have the right to appeal. If you wish to appeal our decision, we recommend you talk to a lawyer.”

Vehicle modifications and assessment services

For people whose difficulty is physical rather than cognitive, NZ Transport Agency notes that “almost any standard production vehicle can be modified”, listing “steering and secondary control aids”, “left-foot accelerators”, “clutch conversions”, “additional car mirrors” and “wheelchair stowage equipment”. Some modifications require inspection and certification to be safe.

For finding a driving assessment service, it points to Accessable and Enable New Zealand — the same two organisations that handle equipment and modification services. Funding for vehicle modifications runs through the same EMS route as other equipment; see equipment and home modifications.

Planning for the day it does end

For most people with Parkinson’s, driving ends eventually. Deciding in advance rather than in a crisis is the difference between a plan and a shock. NZ Transport Agency also has a path for people who “decide on their own, without having a medical review, that they don’t want to drive anymore.”

Do one thing early: apply for Total Mobility before you stop driving, not after. The assessment takes time, and the gap between the last drive and the first subsidised taxi is where people become isolated. See Total Mobility and getting to appointments.

If this applies to you

Your situationWhat to do
You have just been diagnosedA diagnosis does not remove a licence. Talk to your GP or neurologist about where you stand, early rather than late
You are filling in a licence applicationParkinson’s falls under “any other condition that may affect your ability to drive safely”. So does fatigue
Your renewal is coming up and you are over 75You will need a medical certificate. Book the appointment so the certificate is no more than 60 days old at renewal
You are 74½ and applying for a new licence or endorsementThe certificate requirement already applies to you
You have been referred for an occupational therapy assessmentPrepare for judgement, reaction time and visual processing, not only for movement. Revise the road code
You do not currently hold a valid licenceTell the assessor at least a week before, so a temporary licence can be arranged
You were given conditions on your licenceFollow them, and diarise the date any medical report is due. Missing it means revocation
Your licence was revokedYou have a right of appeal, and NZ Transport Agency recommends talking to a lawyer
You are thinking about stoppingApply for Total Mobility first, while you still have transport
