Part 199 gives effect to the regulations in MARPOL Annex VI. Annex VI of MARPOL seeks to address the impact of air pollution from shipping activities on human health and environments in and around port communities, and the impacts of emissions from shipping activities on climate change and ozone layer depletion.

In July 2021, Maritime NZ conducted public consultation on a draft version of the rule. Twenty three submissions were received. The summary of the submissions is included in the pdf of the final rule from page 97.

Amendments to Part 199 and new maritime transport instrument in force

These amendments to Part 199 ensure the NOx emissions regime is fair and workable for domestic ships, enable the creation of two types of transport instrument for technical and detailed requirements under the Rule and make a number of minor and technical amendments.


One transport instrument has been created and comes into force on 1 January 2023, allowing alternative forms of evidence to be used to demonstrate that some types of engines comply with the MARPOL Annex VI NOx emission levels.


The second type of transport instrument will enable the Director to approve equivalents to requirements in the rules, and will be consulted on and created in the future as needed.
