Compliance & Inspections

Japan operates one of the most demanding vehicle inspection regimes in the world. The Shaken (車検, literally “vehicle inspection”) is a mandatory roadworthiness test required for every registered vehicle in Japan. New vehicles receive their first Shaken at three years old, then every two years thereafter. There is no exemption — every car on Japanese roads must hold a current Shaken certificate.

The inspection is exhaustive. Qualified inspectors assess structural integrity, checking the chassis and body for corrosion, cracks, and deformation. The braking system is dynamometer-tested for stopping force, balance, and pedal travel. Suspension components — shock absorbers, bushings, ball joints, and stabiliser links — are inspected for wear, leaks, and free play. The steering system is checked for excessive play at the wheel, worn tie-rod ends, and power steering operation.

Emissions testing measures exhaust gas composition against Japan’s strict limits. The exhaust system is inspected for leaks, corrosion, and mounting integrity. All exterior lighting must function correctly and meet brightness and alignment standards. Windscreen condition, wiper operation, horn function, seatbelt condition, and speedometer accuracy are all verified.

What makes Shaken significant for import buyers is its economic effect. The inspection itself costs ¥1,500–¥2,000 (roughly NZ$17–$23), but the total cost including the mandatory Jibaiseki insurance (compulsory third-party) and weight tax typically runs ¥100,000–¥200,000 (NZ$1,100–$2,200) depending on engine size and vehicle weight. If repairs are needed to pass, costs escalate quickly.

This economic reality means many Japanese owners sell vehicles rather than pay for another Shaken cycle — particularly on cars approaching 7–10 years old. The result is a steady supply of well-maintained, low-kilometre vehicles entering the export market in excellent mechanical condition. A vehicle that has passed multiple Shaken cycles has been professionally inspected every two years of its life — a maintenance history most domestic NZ vehicles cannot match.

Before a vehicle leaves Japan, it must pass a pre-export inspection conducted by an authorised inspection body. The most widely recognised is JEVIC (Japan Export Vehicle Inspection Center), though other approved bodies include JAAI (Japan Auto Appraisal Institute), JEVIS, and BVQI Japan. These organisations are accredited under Japan’s export regulatory framework and recognised by New Zealand’s transport authority.

The pre-export inspection serves a different purpose to Shaken. Where Shaken confirms roadworthiness for Japanese roads, the export inspection verifies the vehicle’s condition and history for the importing country. Inspectors check for undisclosed body damage, including evidence of collision repair, panel replacement, and structural straightening. The odometer reading is verified against Japanese auction records and service history to detect rollback or tampering.

The vehicle is inspected for evidence of flood damage — water marks on upholstery, corrosion in electrical connectors, silt deposits in hidden cavities, and water-damaged electronic modules. Fire damage indicators are checked, including heat discolouration, melted wiring looms, and charred components. The VIN (Vehicle Identification Number) is verified against Japanese registration records to confirm the vehicle’s identity.

If the vehicle passes, an export certificate is issued. This certificate travels with the vehicle and is required by New Zealand Customs for clearance on arrival. Vehicles that fail the export inspection cannot be legally exported to New Zealand. The certificate provides the importing dealer and end buyer with an independent, third-party verification of the vehicle’s condition at the point of departure from Japan.

When a vehicle arrives at a New Zealand port, it enters the jurisdiction of MPI (Ministry for Primary Industries) before anything else happens. New Zealand’s geographic isolation and unique ecosystem make biosecurity a national priority, and imported vehicles are treated as a significant contamination risk.

MPI inspectors physically examine the vehicle’s exterior, interior, undercarriage, engine bay, boot, and wheel arches for biological contaminants. They are looking for soil, seeds, plant matter, insects (alive or dead), spider webs, animal material, and any organic debris that could introduce invasive species or plant diseases to New Zealand.

Particular attention is paid to the undercarriage, where soil and organic matter accumulate in chassis rails, suspension components, and underbody panels. Engine bays are inspected for nesting insects, seed pods caught in air intakes, and biological material lodged around wiring or ducting. Interior carpets, boot linings, and spare tyre wells are checked for seeds, soil, or insect activity.

If contamination is found, the vehicle is directed for treatment — typically fumigation with methyl bromide or heat treatment. In some cases, high-pressure washing of the undercarriage is required. The vehicle cannot proceed to the next compliance stage until MPI clearance is granted. This process protects New Zealand’s agricultural sector and native ecology, and it applies equally to every single vehicle imported, regardless of value or origin.

Once MPI biosecurity clearance is obtained, the vehicle enters the entry certification process overseen by NZTA (New Zealand Transport Agency, now operating as Waka Kotahi). This is the most technically demanding stage and determines whether the vehicle meets New Zealand’s safety and emissions standards for road registration.

Entry certification is performed by authorised entry certifiers — specialist workshops licensed by NZTA. The vehicle is assessed against the Land Transport Rule: Vehicle Standards Compliance 2002 and the Frontal Impact and Side Impact standards (UN/ECE regulations adopted by New Zealand). These standards cover occupant protection in frontal and side collisions, and vehicles must either have been manufactured to an accepted international standard or be physically tested.

The emissions assessment checks whether the vehicle meets New Zealand’s requirements, which are broadly aligned with Japan’s domestic emission standards. Vehicles must comply with exhaust emission limits for carbon monoxide, hydrocarbons, and nitrogen oxides. Evaporative emission controls (fuel vapour recovery) and the catalytic converter are inspected for presence and function.

Theft prevention is also assessed. Vehicles must be fitted with an electronic engine immobiliser that meets the relevant standard. Most Japanese-specification vehicles from 2000 onward have factory-fitted immobilisers, but where one is absent or non-compliant, an approved aftermarket immobiliser must be installed by the entry certifier.

The fuel system is inspected for integrity — fuel lines, connections, tank mountings, and filler cap sealing. Seatbelts are checked for type approval, mounting integrity, and retractor function. Glazing (windscreen and windows) must meet the appropriate safety-glass standards. If any component does not meet the required standard, the entry certifier must rectify it before issuing the entry certificate. Only after this certificate is issued can the vehicle proceed to registration.

The final stage before a vehicle can be legally driven on New Zealand roads is the Warrant of Fitness, issued by a VTNZ, AA, or other authorised WOF inspection station. For vehicles used for entry into the NZ fleet, a WOF is required before first registration. Once registered, vehicles under 12 years old require a WOF annually; vehicles 12 years and older require one every six months.

The WOF inspection covers the key safety-critical systems. Tyres are checked for tread depth (minimum 1.5mm across the full contact width), sidewall damage, age, and correct fitment. Brakes are tested for stopping force, pedal travel, and balance between sides. All exterior lights — headlamps, tail lights, indicators, brake lights, and reflectors — must function correctly and meet alignment standards.

Suspension components are inspected for wear, leaks, and free play. The body structure is examined for corrosion that could compromise occupant safety, particularly around mounting points for seatbelts, suspension, and steering. Glazing must be free of damage that could impair driver visibility. The speedometer must read accurately. Exhaust emissions are checked visually (excessive smoke) and the exhaust system must be gas-tight.

Seatbelts, airbag warning lights, door latches, mirrors, windscreen wipers and washers, and the vehicle’s general structural condition are all assessed. A WOF failure on any item means the vehicle cannot be driven until the issue is rectified and the vehicle re-inspected. The WOF certificate confirms the vehicle met minimum safety standards on the day of inspection.
