Am looking at buying a new helmet to be used for pretty much everything ie commuting , touring and the odd track day. I have looked at the MNZ website regarding helmets and it lists the approved standards but makes no mention of securing systems ie Drings and micro ratchet, other than to say that it must be fitted with a system and that it must be used. I have seen on helmets, standards that do comply but they may have either of the securing systems mentioned. Does anyone no of other sources that categorically state that one system must be used and not the other.
