New Zealand and Australia are the two countries in the world that required people (of all age) to wear a bicycle helmet. The Royal Australasian College of Surgeons campaigned actively to raise public awareness, acceptance and demand, and helmets first became compulsory across Australia from 1991 to 1992. Bicycle helmets became compulsory in New Zealand in January 1994. Shortly after the introduction of MHL nation wide, the statistic shows the bicycle injuries has shifted toward cyclist’s arms by 29%. It is a significant evidence of benefits of wearing a bicycle helmet.
