Official figures show the amount of time children spend walking has dropped considerably.
Two Ministry of Transport reports say walking and cycling by children aged between five and 14 has dropped from an average of two hours and 10 minutes per week in 1989 and 1990, to an hour and four minutes per week in 2010 and 2013.
At the same the number of primary school-aged students being driven to and from school rose from 31 percent to 56 percent over the same periods.
However, the reports also show the biggest users of non-car modes - such as walking, cycling, and public transport - are children and young adults.
