The latest SLSNZ Equipment Specification Manual dated November 2016 states:
6.4 Compliance labels to be secured to the surface of all Ski’s manufactured to SLSNZ specifications.
23.1 All equipment used in Surf Lifesaving New Zealand sanctioned events shall comply with the specifications contained in this manual.
23.2 Surf Boats, Surf Boards, Surf Skis and Surf Canoes shall display one of the following means of indicating compliance with the specifications:
• An SLSNZ approved craft sticker, or
• An SLSA approved craft sticker.
24.2 Scales and other equipment necessary to ensure compliance shall be made available on the day preceding the National championships to allow the checking of equipment and the issuing of compliance stickers for those requiring it.
24.5 Every endeavor should be made to have scrutineering equipment available at major events and a full list of events where SLSNZ will scrutineer equipment will be made available to clubs each year.
From the above it can be seen that a SLSA certification sticker is no longer a requirement to participate at SLSNZ events. If your skis has a SLSA sticker you’re covered, if not it is possible to get a SLSNZ sticker the day before nationals.
