Environmental rules to prevent air pollution from boats

This year, new Marine Protection Rules targeted to reduce emissions from boats came into force. The rules are part of New Zealand’s accession to MARPOL Annex VI, an international agreement that aims to reduce air pollution from ships. As of 1 January 2023, the Part 199 Marine Protection Rules are fully in effect.

The Part 199 apply to New Zealand commercial vessels and recreational boats that operate in the sea. Vessel and boat owners have a part to play in protecting our marine environment, and we can all help to reduce the impact of climate change.

The Part 199 rules don’t apply to vessels that operate solely in inland waters such as lakes or rivers.

Recreational Boats

The main Part 199 rules that will affect recreational boats are around the use of compliant fuel and engines.

If you use diesel or petrol fuel from a retail pump, then you can assume that it is compliant. If you buy in bulk or use heavier fuel oils, check with your supplier.

From 1 January 2023, if you install an engine over 130kW/174HP, then it needs to meet a required emissions level and have specific documentation to be compliant. This applies to newly installed second-hand engines as well as brand new ones.

For more information, including what documentation is acceptable and which existing engines will need to be compliant, see the new Recreational Boats Environment page on the Maritime NZ website.

Commercial Vessels

Operators of commercial vessels should visit the Air Pollution Page on the Maritime NZ website for the requirements that apply to their vessel.

Detailed guidance can be also found in the Guide for Commercial Vessels under 400GT and/or the Full Part 199 guide.
