A man has died after a suspected quad-bike crash in the New South Wales Upper Hunter Valley.

Police said the 60-year-old man went missing from his Blandford home on Saturday night.

The man's body was found this morning after an extensive search by family members, police and a rescue helicopter.

The man's death follows two separate fatalities on quad bikes in the state near Narrabri and Bathurst last Sunday.

A six-year-old girl died after a quad bike crashed, with two girls, both 13, on the bike with her.

A Bathurst man, 60, died in an accident on the same day.

There have been four fatalities from four-wheeled accidents since the beginning of the year, including the seven-year-old boy who died on a quad bike near Griffith, in the state's south-west in January.

SafeWork NSW called for helmets to become mandatory on the vehicles last week in response to those deaths.

The NSW Government announced on Wednesday that it would double the value of quad bike safety rebates to $1,000.

109 people died on four-wheeler motorcycles from 2011 to 2016.
