Heavy vehicle brake testing: CoF and entry certification brake test protocol and procedure

Published 2015 | Version 11

Like almost all other road vehicles in New Zealand, heavy vehicles are required to undergo entry inspection and a periodic safety check in the form of a certificate of fitness (CoF) inspection. Brake testing is a crucial part of this inspection given the critical role brakes play in overall vehicle safety.

Approved independently qualified person (IQP) list

An IQP is a person trained and appointed by the roller brake machine (RBM) manufacturer or their New Zealand agent, and approved by the Transport Agency, to calibrate approved RBMs.

Fit and proper person guidelines

A person or organisation who is responsible for vehicle inspection and certification outcomes is appointed by the NZ Transport Agency. Clause 2.5 (2) (a) of the Land Transport Rule: Vehicle Standards Compliance 2002 includes the requirement for a person to be fit and proper. This document details those requirements.
