The System Design and Delivery Technical advice note (TAN) is a formal memo which keeps all relevant people up to date and aware of any new releases, interim acceptances, changes and updates to technical information, specifications, legislation, etc in relation to highway projects.

This is being used in place of the email memos you may have been receiving from the technical teams across the Highways and Network Operations group.

The Technical advice note series should be seen as the one source of truth associated with changes to our technical requirements.

It is sent to registered users, both internal and external to the NZ Transport Agency.

Subscribe to the SD&D Technical advice note - the one source of truth for highways information.
