A summary of the recently introduced engine rules for New Zealand commercial vessels and recreational boats
This year, new rules were introduced for engines over 130kW (174.3hp) on boats. The rules are part of New Zealand’s commitment to MARPOL Annex VI, an international agreement that aims to reduce air pollution from ships. The ‘Part 199’ marine protection rules apply to New Zealand commercial vessels and recreational boats.
The key rules that affect commercial or recreational vessels are the rules for engines over 130kW. The engine rules reduce the emissions of nitrogen oxides which are harmful to both people and the environment.
In general, engines installed before 19 May 2005 that have not been majorly modified, or engines used solely for emergency purposes or on boats that operate only in lakes or rivers, do not need to adhere to these rules.

What this means is that engines over 130kW installed between 19 May 2005 and 1 January 2023 need to meet emissions limits and have the required documentation by 30 June 2032. Engines over 130kW installed before 19 May 2005 are not required to meet emissions limits or have documentation for these engines.
Engines over 130kW installed on or after 1 January 2023 need to meet emissions limits and have the required documentation for these engines from the date of install. These rules apply regardless of the size of the vessel or boat the engine is installed on.
Essentially if you have a pre 2005 outboard or sterndrive you don’t need any documentation but from mid 2005 to this year you do. That gives you none years to be compliant and it will be up to the engine suppliers to provide the necessary documentation.
