Introduction

1 Purpose and Scope

The NZ Transport Agency Waka kotahi  has prepared this document to assist vehicle inspectors and inspecting organisations achieve correct and consistent standards of alternative fuel system inspection and certification. The purpose of this manual is to enhance the safety of in-service vehicles in New Zealand by conveying to Transport Agnecy-appointed vehicle inspectors and inspecting organisations the conditions of their appointment and the requirements for the inspection and certification of vehicles for operation in service.

The scope of this manual is to set out the statutory requirements for in-service alternative fuel system inspections. This manual is restricted to the in-service vehicle inspection requirements for vehicles fitted with alternative fuel systems using compressed natural gas (CNG) and liquefied petroleum gas (LPG). Vehicles may be inspected for alternative fuel system certification only if the system uses gas for the propulsion of the vehicle. Alternative fuel systems driving auxiliary engines or other equipment may not be inspected for alternative fuel system certification.

Amendments to this manual will be issued from time to time as inspection requirements change and improvements are made. Details of amendments are available from the Amendments tab section. Suggestions for improvement should be made using the feedback button found on every page.
