The family of a 7-year old girl run over and killed on a farm near Twizel at the weekend are working closely with police to work out how the tragedy unfolded, officers say.
The incident happened on a farm track off State Highway 8 about noon on Sunday.
It is believed the girl's father was driving the vehicle at the time and phoned emergency services.
The small Mackenzie District town has rallied to protect the family involved, with shop workers, business owners and residents refusing to talk about the death.
Today, police said investigations are ongoing and the girl's death has been referred to the coroner.
