National Speed Limit Register

The NZ Transport Agency is currently developing a National Speed Limit Register, which will provide a technology-enabled, maps-based central source of speed limits for roads in New Zealand.

Speed limits, and communication of those limits to road users, is core to road safety. Speed limit data is used by the public, enforcers and increasingly by intelligent systems in vehicles. The National Speed Limit Register will make it easier for people to access and utilise that data. Third party consumers will be able to easily access consistent speed limit data from one electronic source.

The register will enable organisations responsible for speed management to more easily comply with the Setting of Speed Limit Rule 2017 and Speed Management Guide, and record, update and share speed limit data, and make more informed speed management decisions.

The development of a national register contributes to the Transport Agency speed management programme.

This is part of the Safe Network programme, a collaborative, prioritised programme of proven safety interventions on high risk routes across New Zealand. The programme uses the Safe System approach focusing on safe roads and roadsides, safe and appropriate speeds and safe rail level crossings. These actions will make roads more forgiving of human error, which will lower trauma rates.

While the register will not change how speed limits are set, it will provide an accurate, national view of speed limits which will inform wider speed management analysis.
