We're contracted to develop the Civil Aviation Rules by the Ministry of Transport for the Minister. Under this contract the Minister of Transport approves a programme of new rules and changes to existing rules each year. Any ordinary rule changes are subject to the Minister of Transport's agreement.

This page is updated monthly to provide progress reports on our current rule projects together with information on recent rule changes that have come into effect.

You can also find a list of current regulatory issues and how to raise your own issue with our regulatory system. 

If you have any queries regarding a rule project, please contact us by emailing docket@caa.govt.nz.

PBN (Performance Based Navigation)


This project looks to ensure that the regulatory framework can support Performance Based Navigation implementation by 2023, as a result of the New Southern Sky programme to meet International Civil Aviation Organization requirements.

The Minister signed the PBN Rules on 5 October 2021.

We are in the process of finalising the 13 additional draft Notices. We are aiming to have these drafts completed for consultation in June 2022 and in force by September 2022.

Publish 13 Notices for public consultation

Runway Condition Reporting


This project proposes amendments to rule 139.103 that requires all aerodromes to provide real-time runway surface condition reporting. Affected aerodromes are currently covered by an exemption to the rule requirement which expires on 5th November 2020. The rule amendments will require aerodromes to provide real time runway surface condition reporting using standardised reporting methods.

Early stage of drafting the Notice of Proposed Rule Making (NPRM), which we will seek approval to consult in July 2022.

Publish NPRM

Assorted Issues 2019/2020


The Assorted Issues policy project consists of a collection of issues that exceed the criteria of an omnibus rule amendment (very minor changes), yet do not warrant an individual stand-alone policy and rules project. Individually, these changes are not likely to meet cost-benefit or significance thresholds to be prioritised for rule development but are good to do from a regulatory stewardship perspective.

The Ministry has agreed to add this project to the 2021/2022 Transport Rules Programme, although work will start once the Runway Condition Reporting is completed.

In the meantime, policy work is actively underway in the form of the development of drafting instructions.

Rule project name Description and purpose of rule Rules and amendment numbers Important dates

ADS-B below flight level 245

This project proposes using a performance-based rule to mandate transceivers for automatic dependent surveillance – broadcasts (ADS-B), initially for aircraft operating in controlled airspace below 24,500 ft (FL 245). Aircraft using ADS-B constantly broadcast their position to other aircraft and air traffic controllers. ADS-B is scheduled to replace the current secondary surveillance radar system, which reaches the end of its life in 2021.
