Federated Farmers says there is no need to enforce an age restriction on the use of farm bikes, despite the death of girl at a motocross track near Huntly in Waikato.
The six -year-old suffered head injuries and died on Saturday when the quad bike she was riding at the Thundercross Valley Bike Park in Glen Murray rolled on top of her.
Federated Farmers says guidelines regarding the use of all-terrain vehicles, such as quad bikes, state that children under 12 should not be permitted to drive them.
However, its health and safety spokesperson Donald Aubrey says it would be unnecessary to enforce an age restriction.
Mr Aubrey says the key lies in education and it is important that young people, particularly between the ages of 12 and 15, are given proper tuition when learning to ride all-terrain vehicles.
The Department of Labour has begun an investigation into the girl's death.
