Research has found farmers are making changes to improve quad bike safety.
With an estimated 850 quad bike injuries on farms each year, the Ministry of Business, Innovation and Employment has been pushing for farmers to take responsibility over quad bike accidents.
A survey by the ministry shows farmers are doing just that, with an increase in helmet sales; 16% of farmers report greater helmet use since 2010.
It also shows farmers taking other safety measures with fewer farmers carrying passengers.
Five out of the 40 work place fatalities recorded in 2012 were from quad bikes.
Despite the survey results, the ministry says quad bike safety is still an issue and it will be increasing unannounced farm inspections over the next month.
A safety campaign was started in 2009.
The ministry's research also included looking at ACC claims.
