Where do I buy compliant road cones? RTL. Our highly visible range of 900mm road cones and durable delineators set the standard for managing traffic, construction and work zone projects in New Zealand. Did you know Safety Cones with black bases are not compliant and cannot be used on the road corridor (footpath, curb, road etc). Buy cones from RTL, that can be used on both private and public land. All 900mm Cones from RTL are NZTA compliant. The PVC  Enviro Cones with Reflective Tape are used everyday in temporary traffic management or the Motorway Cone which is suited for high wind situations, ideal for long term sites and reduces the need for double stacking.
