The objective of this new NZTA M25:2021 specification is to provide guidance for retroreflective sheeting manufacturers wishing to sell their retroreflective sheeting in New Zealand.

This specification covers the requirements that manufacturers and suppliers must comply with before retroreflective sheeting can be approved for use in New Zealand for:

• permanent and temporary retroreflective sheetings for use on traffic signs
• retroreflective sheeting for use in the manufacture of vehicle number plates.

This specification must be read in conjunction with AS/NZS 1906.1:2017 – Part 1(external link) using the same descriptions, definitions, classifications of retroreflective sheeting and colour processed formats.
