National Speed Limit Register (NSLR)

By Oliver Reich

The development of the Waka Kotahi National Speed Limit Register (NSLR) is now complete and went live for road controlling authorities in May 2022, shortly after the Land Transport Rule: Setting of Speed Limits (2022) coming into effect.

While the majority of road controlling authorities have migrated their speed limit data into the NSLR, we are working with the remaining to complete their migration. Under the Setting of Speed Limits (2022) Rule this needs to be completed by the end of July 2022.

The NSLR provides an online maps-based central source of all fixed speed limits for roads in New Zealand. It is the legal instrument for setting speed limits, instead of bylaws, and speed limits are required to be in the NSLR to be legally enforceable.

Third parties will be able to easily access consistent speed limit data from one online source through the Waka Kotahi open data portal. Speed limit data can be viewed and filtered in a table as well as downloaded in a variety of formats. APIs can be used to upload data into other applications.

Members of the public will be able to search for speed limits on all New Zealand roads, obtain details of specific speed limits and obtain certified copies of speed limits through the NSLR web application. The application is expected to be available at the end of June 2022.

Please email if you have any queries about the NSLR.
