Intercity buses lift minimum age for unaccompanied children

How young is too young for a child to travel unaccompanied on a long haul bus trip. From mid next month, Intercity is lifting the minimum age for unaccompanied children from seven to 10 years old. One Christchurch dad is not keen on the changes. Tim Frank's children regularly use Intercity buses to see their grandparents, but now his youngest will have to wait three years before he can join his siblings on board. Tim Frank spoke to Lisa Owen.
