Police in Canterbury are reviewing the search for a 74-year-old man who has been missing for 10 days.
No trace has been found of Raymond Finnie, whose abandoned car was found stuck on a remote dirt road near Hororata last Wednesday.
He had not been heard from since the previous Friday.
Search co-ordinator Phil Simmonds said an extensive ground and air search involving 1100 man-hours had covered a 4 km radius centred on where the car was found.
He said the search data is being reviewed, to determine what to do next.
