本标准旨在规定公路和铁路车辆在陆地上安全运输危险货物的要求。它旨在提供一种遵守《危险品规则》的方法，以及危险品陆路安全运输最佳实践要求指南。2020版包含更新的技术内容，允许用户跟进最新的良好实践和规范。删除重复的国际规范（每两年修订一次）并仅通过引用纳入将证明本标准，并确保本标准适用。此外，本标准还包括仅针对新西兰的危险品运输规定性信息，以及大量参考NZTA规定的《陆路运输法-危险品运输规则》。请注意，修订版NZS 5433。 2012年危险品清单应包括在SNZ HB 54 33∶2021联合国危险货物清单中，与标准相对应，将于2021年初发布。

Objective of this standard is to set out the requirements for the safe transport of dangerous goods on land in road and rail vehicles. It intends to provide a means of compliance with the Dangerous Goods Rule, as well as a guide to best practice requirements for the safe transport of dangerous goods on land. The 2020 version contains updated technical content that will allow users to follow up-to-date good practice and specifications. The removal of the duplicated international specifications (which is revised every two years) and inclusion by reference only will future proof the standard, and ensure that the standard is fit for purpose.¿¿ In addition, this standard also includes prescriptive information on the transport of dangerous goods that is specific to New Zealand only, as well as including considerable reference to the Land Transport Act - Dangerous Goods Transport Rule, regulated by NZTA. Note that the revised NZS 5433.2:2012 Dangerous goods list is to be included in a handbook SNZ HB 5433:2021 UN dangerous goods list as opposed to a standard, due for release early 2021.
