Land Transport Rules – questions & answers

Omnibus Amendment 2013

1. What is the Land Transport Rule: Omnibus Amendment Rule 2013?

Land Transport Rule: Omnibus Amendment 2013 (‘the Omnibus Amendment Rule’) is a document prepared for public consultation that contains proposals to change requirements in a number of existing Land Transport Rules. Annual Omnibus Amendment Rules provide a means for consulting on relatively straightforward Rule changes that are mainly of a technical or editorial nature, or that originate, for example, from the need to reflect current industry best practice or changes to other legislation.

2. What are the amendment Rules resulting from Omnibus Amendment 2013?

For the purposes of consultation, proposed amendments to nine Land Transport Rules were combined into the Omnibus Amendment Rule. Following consultation, the provisions in the Omnibus Amendment Rule were split into the following amendment Rules:

3. What are the reasons for the amendments being made?

The number of relatively minor changes to several Land Transport Rules is necessary for a variety of reasons. These include:

  • clarifying or modifying current requirements to assist understanding and enforcement;
  • removing unnecessary or unintended requirements to reduce the burden of compliance (without diminishing safety standards);
  • amending requirements to accord with current practices and technology;
  • correcting errors in cross-references, descriptions and technical specifications in current Rules.

Consultation and publication

5. When do these amendment Rules come into force?

All the amendment Rules come into force on 1 January 2014. Until the amendment Rules come into force, the current requirements continue to apply.

Printed copies of the Omnibus Amendment Rule and a summary of the proposed changes were made available on request. The Omnibus Amendment Rule and information material were also available on the NZ Transport Agency’s website.

Public notices seeking submissions were published in the daily newspapers in the major centres (Auckland, Hamilton, Wellington, Christchurch and Dunedin) and in the New Zealand Gazette. The NZ Transport Agency received 22 submissions on the amendment proposals. The submissions were taken into account in preparing the amendment Rules for signing.

7. What is the legal basis for the amendment Rules?

The Land Transport Act 1998 allows the Minister of Transport to make Land Transport Rules.

9. How will the NZ Transport Agency make sure people know about the amendment Rules?

A newsletter outlining the Rule changes is sent to the groups and individuals who have registered their interest in Rules that have been amended. Where necessary, the NZ Transport Agency will advise relevant industry groups of the changes. It will also update any relevant Factsheets or other information material available on its website to reflect the changes brought about by the amendment Rules.
