When it comes to heavy vehicle safety, both New Zealand and Australia set a high bar — but the roadworthiness systems behind those standards differ. If you’re comparing NZ COF vs NHVR requirements, or planning a compliant workshop, it’s essential to understand how each country approaches inspection and certification — and what that means for your workshop setup and compliance strategy.
At EquipSpecs, we support workshops on both sides of the Tasman. This guide breaks down the key differences between New Zealand’s Certificate of Fitness (COF) and Australia’s National Heavy Vehicle Regulator (NHVR) and explains how we help you stay compliant no matter your location
What Is a Certificate of Fitness (COF) in New Zealand?
In New Zealand, heavy vehicles must pass a Certificate of Fitness (COF) inspection every 6 or 12 months, depending on their use and age. A COF is a formal check that confirms your vehicle meets all required safety standards.
Approved agents, including VTNZ, VINZ, and private workshops, perform these inspections on behalf of Waka Kotahi. Key inspection areas include:
- Brake performance
- Suspension and steering
- Lighting and visibility
- Structural integrity
- Safety equipment (e.g. fire extinguishers, seatbelts)
A key part of this process is roller brake testing, typically performed with a truck brake tester that meets NZTA certification. For an accurate result, the machine must meet NZTA specifications — including being calibrated periodically by an approved technician.
What Is the National Heavy Vehicle Regulator (NHVR) in Australia?
Australia’s equivalent system is governed by the National Heavy Vehicle Regulator (NHVR). Instead of a single, standardised inspection like the COF, Australia applies a broader Roadworthiness Inspection Scheme under the Heavy Vehicle National Law (HVNL).
Each state or territory may vary slightly in how inspections are enforced, but the NHVR oversees:
- Periodic vehicle inspections
- Operator licensing and compliance
- Access to road networks
- Safety accreditation through Roadworthiness Programs
Brake testing is strongly encouraged (and often required), particularly for PBS-approved vehicles and those operating under accreditation schemes. While not identical to the NZ COF, the underlying principle is the same: regular inspections with high standards.
Key Differences Between NZ’s COF and Australia’s NHVR
| Requirement | NZ COF | Australia NHVR |
| Governing Body | NZTA | NHVR |
| Inspection Frequency | Every 6 or 12 months | State-dependent (varies by vehicle & usage) |
| Brake Testing | Mandatory | Required or recommended depending on scheme |
| Standardised Equipment Use | Yes — NZTA-certified equipment | Yes — but varies by state and operator accreditation |
| Compliance Documentation | COF Pass Certificate | RWIS Certificate or Accreditation Record |
For workshop operators, the key takeaway is that compliance thresholds differ between NZ and Australia — even when equipment performs the same function.

Cross-Border Workshop Compliance: COF vs NHVR
If your fleet or business operates in both countries — or if you’re importing/exporting heavy vehicles — your workshop must be built to meet the strictest applicable standards.
EquipSpecs helps future-proof your investment with equipment that’s:
- Built to last in demanding workshop environments
- Calibrated to relevant standards
- Supported locally with servicing and parts
Don’t let a technicality hold your business back. We’ll make sure your setup is ready for anything — COF or NHVR.
Frequently Asked Questions: NZ COF vs NHVR
The COF (Certificate of Fitness) is New Zealand’s mandatory inspection for heavy vehicles, required every 6–12 months. The NHVR (National Heavy Vehicle Regulator) oversees vehicle inspections under Australia’s Heavy Vehicle National Law, with state-specific inspection rules. Both systems aim to ensure roadworthiness and safety compliance.
Yes. While both systems require brake testing, inspection pits, and safety equipment, each country has its own standards. EquipSpecs supplies and installs equipment certified for NZTA COF inspections and NHVR-compliant setups, helping you stay compliant across both regions.
In New Zealand, COF inspections occur every 6 or 12 months depending on vehicle type and age. In Australia, NHVR requirements vary by state and vehicle usage, but periodic roadworthiness inspections are mandatory for most heavy vehicles.
Yes. EquipSpecs specialises in cross-border compliance solutions. We design and install workshop equipment that meets both NZTA and NHVR standards, helping your business stay compliant whether you operate in NZ, Australia, or both.
Whether you’re in Wanganui or Wagga Wagga, heavy vehicle safety starts with the right workshop equipment. The COF and NHVR may follow different paths, but the destination is the same: safer roads for everyone.
EquipSpecs is here to help you get there — with certified equipment, expert advice, and support every step of the way.
