Federated Farmers is reminding people visiting farms over the holidays to be careful riding quad bikes, following the death of a teenager on Boxing Day.
Rowan Parker, 16, died while riding a quad bike along a coastal track 70km southwest of Balclutha.
He lost control of the bike and and rode over a cliff, falling 150m to rocks below.
The fatal accident happened in the Chaslands area of the Catlins, where the teenager was visiting a farm with friends.
The teenager's death was one of seven in quad bike accidents this year.
Federated Farmers' agricultural health and safety spokesperson Jeanette Maxwell said holidaymakers should ride quad bikes only if they know how to, and bike owners should ensure riders carry out safety precautions.
