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 Waka Kotahi NZ Transport Agency.
