1-1 Alternative Fuel System Installation Certificate

Reason for rejection

Mandatory equipment

1. A vehicle fitted with an alternative fuel system in working order does not have an Alternative Fuel System Installation Certificate (Note 1) (Note 2) (Figure 1–1–1).

2. An LPG fuel system fitted to a vehicle does not comply with an applicable standard specified in Table 1-1-1 (Note 3).

3. A vehicle fitted with an LPG alternative fuel system to NZS 5422: 1987 does not have an identification plate installed displaying:

a) the text ‘LPG’, or

b) the identification number of each container, or

c) the date of installation.

4. A vehicle fitted with an LPG alternative fuel system to AS/NZS 1425 does not have an LP gas compliance plate (one for each container) securely attached to the body work in the engine bay in a clearly visible location (Figure 1–1–2).

5. The installation certificate or identification plate or compliance plate:

a) does not match the vehicle, or

b) does not match the alternative fuel system fitted to the vehicle, or

c) is not legible, or

d) is not valid.

Note 1

Installation certificates are prescribed by the NZ Transport Agency (including its predecessors). The most recent certificate is provided in Sample certification documents.

Note 2

Where no original installation certificate can be produced, a new installation certificate must be issued.

Note 3

LPG systems fitted to vehicles in Australia may meet AS/NZS 1425: 1999 if they were installed between 1999 and 2003. This is acceptable, although that version of the standard was never approved for installations carried out in New Zealand.

Note 4

While the LPG system must be installed to the appropriate version of AS/NZS 1425, the installation plate or certificate may not actually specify the version. In that case, the vehicle inspector may assume that the LPG system was installed to the correct version of AS/NZS 1425.
