About the STMS(C)-NP warrant

The STMS(C)-NP warrant confirms successful completion of the STMS Category C workshop but cannot be used as a practising STMS warrant.

The next step to receiving your practising STMS(C) warrant

For those who need to be practising as an on-site STMS Cat C, there is additional mentoring and a practical assessment completed in a category C road environment.


Waka Kotahi warrants are refreshed every 3 years.

To refresh a STMS Cat C warrant the holder will need to attend a STMS refresher workshop. This renews the non-practising warrant.

The practising STMS Cat C warrant is renewed once the STMS Cat C practical re-assessment has been successfully completed.

The practising warrant will expire on the same date as the non-practising warrant.
