B.
Authority Card Frequently Asked Questions:
Why / When do I need an Authority Card?
An Authority Card is required to certify dedicated motorsport modifications and is used to obtain a WOF
What are the basic conditions?
The applicant must hold a current MotorSport NZ Competition licence and the vehicle must comply with the alternative standards and be used in a minimum of two(2) motorsport events per year.
Am I the only person who can drive the vehicle?
Use of the vehicle is not restricted solely to the applicant (the licence holder who the Authority Card has been issued to) although it does remain their responsibility.
How long is the card valid?
The Authority Card remains valid concurrent with the applicant’s licence. This will normally be 12 months if the card is applied for at the same time as the applicants Competition licence, although it will be less if applied for during the validity of the Competition licence; as it will expire at the same time as the licence.
Why do I have to renew the card (every year)?
This is because the Authority Card runs concurrently with the holders Competition licence and this ensures (as per the agreement between MotorSport NZ and the NZTA) that only current licence holders may have such specialist exemptions. It also ensures the applicant takes responsibility for the condition and maintenance of their vehicle relative to the modifications listed.
My vehicle has ‘other’ modifications that are not included on the card?
The Authority Card only covers ‘dedicated’ motor sport modifications hence all other applicable modifications should be covered under the LVV Code and detailed on a ‘certification plate’ attached to the vehicle.
What if I add or delete any of the modification categories on the vehicle (that is detailed on the card)?
A new application is required which will entail a physical inspection to be performed by an ‘A’ Scrutineer. All items on the card will be checked for compliance.
If nothing is changed on the vehicle and I renew the card every year will I ever need to have the vehicle inspected again?
Yes, this will happen automatically as part of the Safety Audit system performed at events.

Safety Structures (Roll Protection):
5.1

Design Specification: The function of a Safety Cage is to reduce the risk of serious injury to the Occupants during competition. The ability of a Safety Cage to provide protection is dependent upon the quality of design and construction. The following essential design specifications shall be incorporated:

(1)
Longitudinally, the structure shall be entirely contained within the confines of the front and rear shock absorber bodyshell mounts (excluding Single Seater and Sports Racing Cars), and
(2)
For closed vehicles the structure must be as close fitting to the interior profile of the bodyshell as practical, and
(3)
Members of the structure must not unduly impede the entry, exit, or access to the Occupant(s) of the vehicle, and
(4)
Members of the structure must respect the headspace requirements designated by the shaded area in Diagram 8.3 in Part One. For all open vehicles the height of the main rollbar shall be at least 50mm above the top of the helmet of the normally seated Occupant(s) (refer diagram 5.1 below), and
(5)
Where used all fasteners must be self locking M8, ISO 8.8 or greater, and
(6)
No fluids may pass through any tubing forming part of the Safety Cage, and
(7)
Each Safety Cage must be identified by means of an identification number (being the MotorSport NZ Homologation number) or a plate permanently affixed by the manufacturer bearing the name of the manufacturer, the MotorSport NZ homologation number, and the individual serial or series number of the structure; this ID plate must neither be moved or copied.
(8)

The structure must be designed to suit the particular vehicle application respecting the aforementioned design specifications.

5.3

Welding:

(1)
All welding shall be of the highest possible quality and preferably using a gas-shielded arc. Although good external appearance of a weld does not necessarily guarantee its quality, poor appearance is never a sign of good workmanship. Grinding welds to alter the appearance is not permitted.
(2)
Where a member of the Safety Cage terminates at another member or a reinforcing plate / mounting foot / footing box, welding shall be carried out around the entire perimeter of the tube. Mandatory for all principle structures. For optional members where this is impracticable ‘best welding practices’ must be observed.
(3)
Where attaching reinforcing plates to the bodyshell, 20mm stitch welding is permitted.
