You've packed the motorhome, hitched up the boat trailer, and you're cruising north for a long weekend. Then you're pulled over and weighed, and told you're driving on the wrong licence.
You're stunned. Your motorhome only needs a Class 1 car licence, and you've driven it that way for years without a problem. So what changed?
The trailer. Add its weight to the motorhome's, and you can cross into "heavy" territory without realising – where the rules shift, and a Class 1 licence no longer covers you. It's an easy trap to fall into, and it all comes down to the one number that drives nearly every motorhome rule in New Zealand: weight.
Because heavier vehicles carry more risk, the New Zealand Transport Authority (NZTA) has stricter rules around who can drive one.
In this blog, we'll cover when you need a Class 2 licence, what the medical involves, and how the inspection and speed rules change once your motorhome counts as "heavy."
What size motorhome can I drive on a standard Class 1 New Zealand licence?

Your standard full Class 1 car licence covers any motorhome with a Gross Laden Weight (GLW) of 6,000 kg or less. That's a lot of motorhome – more than enough for the vast majority of vehicles on the market.
If you're still on a learner or restricted licence, the limit is a little lower: the actual on-road weight can't exceed 4,500 kg.
Interestingly, this is far more generous than the rules across much of Europe, where a standard car licence only covers vehicles up to 3,500 kg. That's why a lot of motorhomes imported from Europe are built to sit under that 3,500 kg mark, even though New Zealand law would happily let you drive something heavier on your Class 1.
When exactly do you need a Class 2 licence for a New Zealand motorhome?

There are two situations where a Class 2 licence becomes a legal requirement.
The first is straightforward: any standalone motorhome with a GVM above 6,000 kg (and up to 18,000 kg) needs a Class 2 licence.
The second catches a lot of people out – towing. If the combined weight of your motorhome and whatever you're towing exceeds 6,000 kg, you need a full Class 2 licence, even if the motorhome on its own sits under 6,000 kg.
Here's a real-world example. Say you've got a motorhome with a GVM of 4,400 kg, and you hook up a trailer with a GVM of 2,000 kg. Individually, each is well within Class 1 territory. But combined, they add up to 6,400 kg, which pushes you over the limit and into Class 2 requirements.
So if you're planning to tow a car, a boat, or a trailer behind your motorhome, do the maths on the combined figure before you assume your Class 1 has you covered. It's always worth confirming your specific motorhome's maximum towing capacity too, because that will tell you how much headroom you actually have.

The rules above reflect NZTA requirements as of 2026 and are intended as a general guide only. Weight limits, medical standards, and inspection rules can change, so always confirm the current requirements with NZTA or a licensing agent, and check the specific GVM and towing capacity of any motorhome before you buy.
What is involved in the NZTA Class 2 medical certificate assessment?

Anyone applying for a Class 2 licence needs to show they're medically fit to drive. This is done using the official DL9 medical certificate.
A few key things to know:
-
A New Zealand-registered health practitioner must complete the certificate.
-
A standard DL9 assessment covers blood pressure, BMI, blood glucose, vision, hearing, range of movement, and fatigue screening. In some cases, a more thorough assessment may be needed, which can include neurological checks, an ECG, cognition testing, and urinalysis.
-
The appointment usually takes around 45 minutes and is often carried out by a trained occupational health nurse.
-
The completed certificate must be no more than 60 days old when you present it to NZTA.
As a rough guide on cost: a standard DL9 medical typically runs around $110, though it varies between providers, and drivers aged 65 and over may need an additional cognitive assessment (often about $35 more). While most people renew their medical every five years, the intervals get shorter as you age or if you have a health condition to monitor – so for older buyers, this becomes a recurring commitment rather than a one-off.
Think carefully about whether you really need a Class 2 licence before committing to a heavier motorhome – it's a step up in hassle and cost. If a slightly lighter motorhome would suit you just as well and keep you on your existing Class 1, that's often the simpler path. Plus, a heavier motorhome is only as useful as the licences behind the wheel: if your partner drives on a Class 1 licence, a vehicle that requires a Class 2 rules them out of driving it at all.
How do I get a Class 2 licence for a heavy motorhome in New Zealand?

To be eligible, you'll need to have held a full Class 1 licence for at least six months, be at least 18 years old, be medically fit to drive, and pass an eyesight screening test.
From there, the process runs like this:
-
Get your DL9 medical from your GP or an occupational health provider. Remember that it needs to be within 60 days of your test.
-
Sit the learner theory test at a licensing agent (an AA or NZTA agent). Alongside standard road code questions, this test covers truck-specific topics like load securing.
-
Complete practical training with a Class 2 driver trainer.
-
Sit your practical driving test to earn your full Class 2 licence.
A shortcut: normally you'd hold your Class 2 learner licence for a period before progressing, but if you complete an NZTA-approved Class 2 course, you can go straight from learner to full licence without the wait. These courses bundle the theory unit standards, practical training, and assessment together, and typically cost somewhere in the region of $800–$900. For anyone who wants their licence sorted before picking up a new motorhome, that can be the fastest route.
Budgeting it all together – medical, theory, training course, and licence fees – a realistic all-in figure for a Class 2 sits roughly around $1,000 to $1,100, depending on the provider and how much training you need.
-
The DL9 certificate must be no more than 60 days old when you submit it to NZTA. However, once accepted, that medical assessment generally covers you for up to five years.
In practice, that means most Class 2 holders provide a fresh medical certificate every five years at renewal. The exception is if you develop a new medical condition, or an existing one worsens, in which case you'll need a new certificate sooner, regardless of where you are in the five-year cycle.
-
This comes down to weight. A motorhome is classed as heavy once its GVM exceeds 3,500 kg. Any vehicle with a GVM of under 3,500 kg needs a Warrant of Fitness (WoF), while vehicles with a GVM of over 3,500 kg will require a Certificate of Fitness (CoF).
From 1 September 2025, CoF inspections on privately owned heavy motorhomes changed from every six months to every 12 months.
To qualify for the annual CoF, your motorhome needs to be genuinely set up as a mobile dwelling, with at least one sleeping berth, cooking facilities, and a toilet. It can't be used to carry passengers for hire or reward, or be operated under a transport service licence. If your motorhome is used commercially (for rental, say), the standard heavy-vehicle CoF rules still apply.
-
This depends on which inspection type your vehicle runs under. Vehicles operating on a WoF can travel up to 100 km/h on the open road, while vehicles operating on a CoF are capped at 90 km/h.
-
Not automatically. NZTA can decide you're medically fit to drive with certain conditions attached. Some common examples include sleep apnoea – you can still drive if it's well controlled (for instance, with a CPAP machine), though you may be asked to provide compliance data from the device. The same goes for Type 1 or Type 2 diabetes – you need to show that it is well managed.
Common licence conditions might include wearing corrective lenses, driving automatic-only vehicles, having rear-view mirrors on both sides, or not driving after dark. In more complex cases, NZTA may still grant a licence after consulting your health practitioner and any relevant specialist, usually with specific conditions in place.
