Latest updates

We regularly consult with the sector to gain insights that help us to review and update the documents within our Standards and Guidelines Catalogue. Information on current consultations can be viewed in our public consultation hub, and further information on recently reviewed, updated or archived documents is shared with staff and suppliers in our regular Standards and Guidelines Technical Advice Note newsletter.

Publication consultation hub

Technical Advice Notes were previously published every time an individual operational policy document was ratified and updated in our standards catalogue. However, in 2024 we have updated the format into a regular newsletter that not only lists recently updated documents, but also notifies future consultations and highlights upcoming plans in our forward work programme.

An archive of our previous Technical Advice Notes is below.

To search for a specific archived policy update if you can’t see it here, use the search filters in our NZTA resources library.

As of May 2016, we have migrated all the information and pages of our Highways Information Portal (HIP) into nzta. govt. nz to give it the same look and feel as our external website as part of an Transport Agency-wide consolidation exercise. Highways Information Portal 
http://www. nzta. govt. nz/roads-and-rail/highways-information-portal/

If you have the HIP bookmarked, please update the bookmark in your internet browser to this new address. An automatic redirect will ensure anyone trying to access the old HIP pages will be taken directly to the new HIP pages. Content and structure of the site is largely unchanged, with the exception of SAP and TIO being moved into the Processes section. We have also incorporated the Air Quality and Acoustics websites of the Environment and Urban Design team into the new HIP.
