Technical advice note

The Transport Services 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 Transport Services 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.
