The Department of Labour says too many people are still being killed in work-related accidents while using ATV quad bikes on farms.
In the 12 months to the end of June, four people died, all in the Waikato and Bay of Plenty regions.
In the previous year, six people died while using quad bikes, four of them in Waikato and Bay of Plenty.
The department's Chief Health and Safety Advisor, David Tregoweth says there is no apparent reason for the higher fatality rate in the two regions.
He says more people in those regions use the machines, both in farming and the adventure tourism industry.
Mr Tregoweth says the same issues regarding safe use of ATVs applies everywhere.
He says all farmers need to look at hazard handler on the Department of Labour website.
