In-service certification (WoF and CoF) - Heavy vehicles

Correct as at 27th April 2024. It may be superseded at any time.

1 Vehicle identification

1-1 VIN and chassis number

Important Ensure that the VIN or chassis number is recorded in full on the checksheet.

This number must be:

  • the VIN if fitted – not the chassis number (locally allocated VIN)
  • the stamped VIN on the VIN plate – not the VIN etched on the glazing.

Also refer to Table 1-1-1. Location of New Zealand VIN numbers, Figure 1-1-1.  Structure of a VIN issued by the NZ Transport Agency and Figure 1-1-2. Structure of a VIN issued by the vehicle manufacturer.

Reasons for rejection

Mandatory requirements

1. A vehicle first registered or re-registered in New Zealand before 1 April 1994 does not have a VIN or chassis number (Note 1) (Note 3).

2. A vehicle first registered or re-registered in New Zealand from 1 April 1994 does not have a VIN number (Note 1) (Note 3).

3. A VIN number is not valid (Note 1) (Note 2).

Condition

4. A VIN or chassis number has been (Note 1) (Note 3):

a) removed, or

b) erased, or

c) altered, or

d) defaced, or

e) obscured, or

f) destroyed, or

g) obliterated, or

h) affixed unlawfully or by unauthorised persons.

Note 1

The vehicle inspector must notify Waka Kotahi using the vehicle report form if there is reason to believe that the VIN or chassis number has been tampered with in any way.

The vehicle inspector must not issue a WoF/CoF/permit until approved by Waka Kotahi. Approval will usually include the issue or re-issue of a new VIN plate.

The vehicle inspector must not issue a WoF/CoF/permit if there is reason to believe that the VIN or chassis number has been tampered with in any way.

Refer the vehicle to a VIN issuing agent (VTNZ, VINZ, NZAA, Drivesure, CVC, i4Checkpoint). They will inspect the vehicle and seek approval from Waka Kotahi to issue or re-issue a VIN plate. Once the vehicle has been approved the vehicle may continue through the inspection process.

Note 2

A valid VIN is a unique number that has been assigned to the vehicle in the vehicle’s country of origin or by a person appointed by the NZTA. It consists of 17 characters that never contain the letters I, O or Q, and that is capable of being decoded to provide identifying information about the vehicle.

Note 3

If the vehicle is failed because the VIN/chassis is missing or unreadable, then 'not found' must be recorded in place of the VIN number on the check sheet.

Table 1-1-1. Location of New Zealand VIN numbers

Vehicle

Permitted VIN locations

Vehicles that are not forward controlled (passenger cars and off-road passenger vehicles)

  • In the engine compartment on the right-hand side of the firewall
  • In the engine compartment on the right-hand side adjacent to the front suspension mounting point
  • In a location inside the engine compartment approved by Waka Kotahi for a specified vehicle or vehicle model
  • On the firewall or inner guards so it is visible from the front of the vehicle.

Forward-controlled vehicles
(passenger vans and off-road vehicles)

  • In the passenger compartment, on the top of the right-hand side wheel arch adjacent to the seat cushion
  • In the passenger compartment, on the inner panel of the right-hand A-pillar, adjacent to where the floor meets the A-pillar

Note 1 Definitions

Chassis means the structural lower part of a vehicle to which the running gear and, as applicable, engine, transmission, steering system and body may be attached.

Chassis assembly means a chassis with running gear attached and, as applicable, engine, transmission and steering system attached.

Body means the part of the vehicle that is designed for the use and accommodation of the occupants or to hold any goods.

Note 2

Rust stains can indicate fretting or movement between two components, eg as a result of loose fasteners or cracking.

Note 3

Chassis cracking is most likely to occur in the following areas:

  • abrupt changes in chassis section
  • adjacent to welds
  • body mounting points
  • adjacent to loose fasteners
  • notches.
Note 4

Corrosion is most likely to occur in areas where moisture is retained, or when the vehicle is used to carry stock, fertiliser or corrosive cargo.

Note 5

An alarm must be visible or audible from the driver’s seating position, and the alarm must operate when the vehicle’s engine is running, except when the parking brake is fully applied or when the gear selector of a vehicle with an automatic transmission is in the ‘park’ position.

Note 6

Dents smaller than 5mm deep and 40mm in diameter (to the outer edges of the crease), such as those caused by hail, in the pillars, cant rail or any other similar roof structure, should not be considered to affect the vehicles structural integrity. Any damage larger than above should be referred to a repairer for additional information (see Figure 3-1-4).

Table 3-1-2. Requirements for HVS certification

HVS certification is required

HVS certification is not required

1. Repairs to a structural component of a monocoque body.

2. Repairs to a chassis cross-member, ie:

a) the first or last cross-member of the chassis

b) a cross-member that is fitted within 500mm of an engine mount, transmission mount, or suspension support

c) a cross-member to which a driveshaft centre bearing is fitted

d) a cross-member that supports any of the following:

i. ballrace turntable

ii. tow coupling

iii. fifth wheel

iv. kingpin

v. bolster attachment

vi. hoist, hydraulic cylinder of a tipping body or any other device that may place a concentrated load on the chassis.

3. Repairs to a coaming rail that supports a certified load anchorage point or J-hook, or that secures a load-rated curtain.

4.Modifications carried out on or after 1 April 2005 that may result in increased stress to a localised area of the chassis or significant redistribution of the load over the chassis (eg fitting of a hoist, crane, tipping body, or other special equipment, etc.).

For modifications carried out before 1 April 2005 it is up to the vehicle inspector to determine if certification is required. Individual certification is only required when the vehicle inspector determines, on reasonable grounds, that the component presents a safety risk.

5. Modifications carried out on or after 1 November 2018 to structural reinforcements of the cab/body likely to affect occupant protection (eg cut-outs through pillars, roof rails, reinforcements (not merely stiffeners), etc) for modifications such as campervan, crewcab, truck/bus conversions.

1. Repairs to a non-structural component of a monocoque body (eg a body panel).

2. Repairs to a first failure of a chassis cross-member except a repair listed in the left-hand column.

3. Repairs to a coaming rail that does not support a load anchorage point (including a stock crate J-hook) or that does not secure a load-rated curtain.

4. Any modification or repair likely to have been carried out before 1 January 1997 (modifications and repairs before this date generally required certification but for inspection purposes no evidence of this is required).

5. Any repair or modification not listed in the left-hand column unless the vehicle inspector considers that certification is required because the modification or repair has affected the vehicle’s safety performance (a second opinion from an expert may be needed).

6. Any Japanese-market imported used 4x2 (or 4x4) vehicle that has had its tipper body or tail lift mounted as original equipment does not require HVS certification, provided the vehicle inspector is satisfied that the vehicle was registered in Japan in that configuration. This applies to all makes of vehicles. The vehicle and body should be free from damage, repairs or modifications when presented (Note 7).

7. There is evidence of certification of the modification from the company that carried out the modification (ie a statement of compliance or a second stage certification plate or label). See Technical bulletin 13: Acceptable overseas proof of modification.

8. Modifications to the structure of a cab on or before 31 October 2018. This is under a temporary class exemption from specialist certification until 1 October 2026 (see New Zealand Gazette notice 2021-au4295). Note: condition and performance reasons for rejection still apply.

Note 7

Some new trucks imported from Japan fitted with tipper bodies in Japan can be accepted without an LT400. See Technical bulletin (CoF) 8 for a list of the makes and models that can be accepted without an LT400.

Figure 3-1-3. Rust heave limits

Rust heave beyond the limits described above is acceptable only if an HVS certifier with the HVEC category has confirmed in writing that at the time of inspection the identified chassis rust heave on the vehicle remains within safe tolerance of the vehicle’s state of manufacture. Confirmation from the HVS certifier should be kept with the checksheet. The identity of the HVS certifier must be recorded in the Landata GNOTE page. This assessment is only valid for that specific CoF inspection.

Regardless of any expiry date, an inspector may refer the vehicle to an HVS certifier if he/she suspects that the safety of the vehicle is compromised, eg due to excessive corrosion or chassis cracking. If the chassis is repaired, an LT400 is required.

17. Where a headlamp comprises an array of light sources (eg LEDs) fewer than 75% of these operate.

Modifications

18. An overlay has been applied that reduces or distorts the light emitted from the lamp (eg a tinted cover).

19. A headlamp is retrofitted with a type of light source other than that specified by the vehicle manufacturer or the headlamp manufacturer (eg a headlamp designed for a halogen bulb is fitted with any other type of light source such as an HID or LED bulb, or any other light source such as LED strips or non-OEM angel eyes) (Note 8).

20. Retrofitted headlamps are not fitted:

a) as a pair, or

b) symmetrically, or

c) as far towards each side of the vehicle as is practicable.

21. A retrofitted dipped-beam headlamp on a vehicle with a GVM of 12,000 kg or less is positioned at a height exceeding 1.2m from the ground (Note 9).

Note 1

An original equipment (OE) lamp is one that is fitted by the vehicle manufacturer in the original position, or is an equivalent replacement or aftermarket lamp suitable for the position provided by the vehicle manufacturer for that lamp. All other lamps are considered retrofitted (ie non-OE).

Note 2

If the dipped-beam headlamps are able to be adjusted from the driver’s seating position, the alignment must be checked with the adjustment at its highest position.

Note 3

If the vehicle is fitted with self-levelling suspension, the alignment must be checked with the suspension at its normal level.

Note 4

Modify means to change a vehicle from its original state by altering, substituting, adding or removing a structure, system, component or equipment, but does not include repair.

Repair means to restore a damaged or worn vehicle, its structure, systems, components or equipment to within safe tolerance of its condition when manufactured, including replacement with undamaged or new structures, systems, components or equipment.

Headlamp means a lamp designed to illuminate the road ahead of a vehicle, and that is a:

a) dipped-beam headlamp (single lamp), or

b) main-beam (high-beam) headlamp (single lamp), and includes a driving lamp, or

c) combination of a dipped-beam headlamp and a main-beam headlamp (dual-lamp unit).

Dipped-beam headlamp means a headlamp that is designed to emit a dipped beam, which is a beam of light that is angled downwards in such a way that it prevents undue dazzle or discomfort to oncoming drivers and other road users.

Main-beam headlamp means a headlamp that is designed to illuminate the road over a long distance ahead of the vehicle.

Note 5

If a headlamp is fitted with a readily removable cover, other than a clear protective cover, this must be removed for inspection of the headlamp.

Note 6

A vehicle originally manufactured with a headlamp arrangement that differs from what is required or permitted in this section may retain the original headlamps provided they remain fitted in their original position and perform as intended by the vehicle manufacturer.

Note 7

A forward-facing permitted lamp that does not comply with the equipment, condition and performance requirements must be made to comply or be removed from the vehicle.

Note 8

A high-intensity discharge (HID or Xenon HID) or LED conversion kit consists of an HID or LED bulb which fits into the original headlamp unit in place of the original bulb with no change to the headlamp lens, reflector or housing.

It is illegal to fit an HID or LED conversion kit to a vehicle as it brings the headlamp out of standards compliance by producing poor beam patterns and light that is often far too bright to be safe. The bulbs can also produce light that is noticeably blue and not the required substantially white or amber colour. Vehicle and headlamp manufacturers do not permit this modification, and these kits cannot be LVV certified.

It is permitted to replace a complete halogen headlamp unit with a complete HID or LED headlamp unit. If the vehicle is required to meet an approved safety standard for headlamps, only approved headlamps can be retrofitted (see Figure 4-1-1).

Note 9

The dipped-beam headlamps may be positioned at a height exceeding 1.2m if a road maintenance implement (eg, snowplough or roadsweeper) fitted to the front of the vehicle would obscure headlamps placed at a height of 1.2m or less.

Note 10

It is acceptable for a pair of dipped-beam headlamps to consist of one symmetric and one asymmetric dipped-beam headlamp. However, in some cases this may result in one lamp being noticeably brighter than the other lamp in the pair. In that case, the vehicle inspector may determine that the dipped beams differ noticeably in light intensity, and the lamps fail the inspection. Note that a beamsetter’s luxmeter cannot measure the light intensity of a dipped beam headlamp.

Note 1

Fog lamp means a high-intensity front or rear lamp designed to aid the driver or other road users in conditions of severely reduced visibility, including fog or snow, but not including clear atmospheric conditions under the hours of darkness.

Note 2

A rear fog lamp that does not comply with equipment, condition and performance requirements must be made to comply or be disabled so that it does not emit a light.

Note 3

If a front fog lamp is fitted with a readily removable cover, other than a clear protective cover, this must be removed for inspection of the fog lamp.

Note 4

A vehicle originally manufactured with a front- or rear-fog-lamp arrangement that differs from what is required or permitted in this section may retain the original front or rear fog lamps provided they remain fitted in their original position and perform as intended by the vehicle manufacturer.

Note 5

A forward-facing permitted lamp that does not comply with the equipment, condition and performance requirements must be made to comply, be removed from the vehicle, or be disabled so that it does not emit a light.

Note 1 Definitions

Air brake means a brake, the operation of which requires the use of compressed air.

Anti-lock braking system (ABS) means a device that senses that one or more of the wheels is starting to lock-up during braking and regulates the braking forces automatically and effectively to prevent it.

Auxiliary brake means a device, other than a service brake or parking brake, fitted to a vehicle to enable the driver to control its speed, whether or not it is suitable to stop the vehicle.

Dedicated combination means a combination of vehicles certified for use in combination where both vehicles are affixed with a plate clearly and indelibly marked with the VIN or chassis number of the other vehicle.

Emergency brake in relation to any vehicle, or combination of vehicles, means the system that makes it possible to undertake a controlled stop of the vehicle or combination in the event of the failure of the service brake. (Emergency brakes must act as directly as practicable without any interposition of any differential gearing.)

Foundation brake means the basic brake assembly fitted to each axle or road wheel which produces the braking force necessary to bring a vehicle to a stop; and includes the complete drum or disc brake.

Hydraulic brake means a brake that utilises hydraulic pressure to activate the foundation brake, whether its operation is assisted by compressed air, vacuum or any other means.

Modify means to change the vehicle from its original state by altering, substituting, adding or removing any structure, system, component or equipment; but does not include repair.

Parking brake means a brake that is designed for keeping the vehicle stationary, and that is readily applicable and capable of remaining applied for an indefinite period without further attention. (Hydraulic locking devices are not acceptable as parking brakes. The parking brake must be applied by solely mechanical means.)

Repair means to restore a damaged or worn vehicle, its structure, systems, components or equipment; and includes the replacement of damaged or worn structures, systems, components or equipment with equivalent undamaged or new structures, systems, components or equipment.

Reservoir for the purpose of the Heavy-vehicle Brakes Rule, means a device designed and constructed to store fluid, compressed air, compressed gas, or vacuum; and does not include pipes, valves, hoses, or booster cylinders operated by vacuum or compressed air.

Service brake means a brake for intermittent use that is designed for the purpose of slowing down and stopping the vehicle.

Trailer brake hand control means a hand-operated control capable of applying the service brake of the trailer or trailers.

Wheel means a rotating load-carrying member between the tyre and the hub, which usually consists of two major parts, the rim and the wheel disc, which may be manufactured as one part, or permanently attached to each other, or detachable from each other; and includes the tyre fitted to the rim.

Note 2

For in-service inspections standards compliance must be verified when there is reason to believe a hose or flexible tubing does not comply or when it forms part of a brake modification or repair.

Note 3

A vehicle may be fitted with more than one gauge, but only one gauge that indicates the pressure in one service brake reservoir is necessary. A gauge fitted to a supply reservoir (wet tank) cannot be used to indicate the pressure in a service brake reservoir.

Note 4

Towing vehicle protection means a means by which the air brake system of a towing vehicle is protected from loss of air pressure in the event of failure of the trailer’s brake system, or when the trailer becomes disconnected from the towing vehicle.

Note 5

Protection, in this case, means a system to prevent the operation or failure of the device lowering the pressure in any service brake reservoir below the pressure specified by the vehicle manufacturer or brake manufacturer or, if this information is not available, two-thirds of the maximum operational pressure specified by the vehicle manufacturer or brake manufacturer. (Air auxiliaries have to be inspected at Entry certification however they do not have to be tested for in-service inspection provided:

  • they have been fitted as standard equipment by the vehicle manufacturer or their approved New Zealand agent, or
  • they are connected to an auxiliary take-off point provided by the vehicle manufacturer).
Note 6

A pressure gauge must indicate the pressure in pressure units, or on a coloured scale, or in an equivalent way. The gauge display must be visible, though it may be multi-functional, ie have the ability to display various items including the air pressure.

Note 7

For the purpose of testing the brakes, the vehicle shall be presented with a load of at least 65% of the road legal limit, or be subject to equivalent load simulation (refer to the NZ heavy vehicle brake test protocol).

Note 8

Where the minimum safe operating pressure is not specified by the vehicle or brake manufacturer, the minimum safe operating pressure is taken as 50% of the correctly adjusted cut-out pressure for the compressor or governor.

Note 9

Protection, in this case, means a system to prevent a brake failure that lowers the pressure in one service brake circuit below the minimum safe operating pressure from lowering the pressure in any other service brake circuit below the minimum safe operating pressure or pressure specified by the vehicle manufacturer or brake manufacturer.

Note 10

A supply reservoir (wet tank) is a brake reservoir from which the service brake reservoirs receive compressed air.

Note 11

The ABS system must be cycled, this can be done by shutting down the vehicle engine and returning the ignition to 'on' only, observe ABS warning light operation and listen for a clicking or chuffing sound from the modulator or valve unit.

  

Check wheel sensors and pulse rings (if visible) and for trapped wiring or damaged air lines.

11-2 Exhaust emissions

Reasons for rejection

Performance

1. A vehicle with the engine at normal operating temperature (Note 1) emits clearly visible smoke (Technical bulletin 8) from the exhaust tailpipe (Note 2):

a) for a continuous period of five seconds when the engine is idling and does not meet the additional requirements in Table 11-2-1, or

b) as the engine is being rapidly accelerated to approximately 2500rpm or approximately half the maximum engine speed (whichever is lower) and does not meet the additional requirements in Table 11-2-1.

2. A vehicle (other than group L vehicle or a class MA or MC motorsport vehicle with a valid motorsport authority card) that was first registered in New Zealand on or after 1 May 2010 and manufactured from 1 January 1990 has a catalytic converter (or diesel particulate filter (DPF) in the case of diesel powered vehicles) removed where there is evidence that one was originally fitted, and there is no written evidence issued by an entry certifier that the vehicle passed a prescribed metered emissions test in this condition (Note 5) (Note 6) (Figure 11-2-1).

Note 1 Test procedure:

a) Carry out the idling and acceleration tests in Reason for rejection 1. A vehicle that passes both tests with the engine below normal operating temperature is deemed to have passed with the engine at normal operating temperature.

b) If the vehicle has failed either test, ensure the engine is at normal operating temperature. Then purge the system by increasing the engine speed to 2500 rpm (or half the maximum engine speed if this is lower) and holding it there for about 5 seconds. Repeat the idling and acceleration tests in Reasons for rejection 1.

Note 2

Visible emissions caused by the condensation of water vapour do not count as smoke.

Note 3

Acceptable evidence is:

a) a letter on the letterhead of the manufacturer or manufacturer’s representative, or

b) a letter on the letterhead of an appropriate automobile club, or

c) evidence of equal authority to (a) or (b) above, eg from an appropriate expert.

Note 4

The vehicle inspector may need to take into account further information about unusual or older vehicles, eg from an appropriate expert such as an office holder in a vintage car club.

Note 5

This reason for rejection does not apply if the vehicle operator can provide evidence that the vehicle was first certified for entry before 1 May 2008.

Note 6

The metered emissions test can only be carried out at entry certifier sites (VTNZ, VINZ, NZAA) where entry inspections are carried out. The entry certifiers will issue a document (Figure 11-2-1) that identifies the vehicle, whether or not the vehicle has passed the test, and whether or not the vehicle was tested with any OE catalytic converters removed. A metered emissions test is not required if a catalytic converter is refitted, or if there is evidence that the vehicle was not originally fitted with a catalytic converter.

1. Document produced by the vehicle operator that proves that (Note 3):

a) the engine is original equipment for the vehicle, and

b) its design means that the vehicle cannot reasonably comply with the visible smoke emission requirements.

Note No evidence is required if, during the acceleration test, a diesel-powered vehicle emits moderate smoke caused by turbo lag.

2. The smoke produced is not noticeably and significantly more visible than it would have been when the vehicle was manufactured and supplied with the fuel recommended by the manufacturer.

First registered before 1 January 1960 with four-stroke engine manufactured before 1 January 1960, or

Vehicle with two-stroke engine or rotary engine.

The smoke produced is not noticeably and significantly more visible than it would have been when the vehicle was manufactured and supplied with the fuel recommended by the manufacturer (Note 4).
