Police hold fears for the safety of a runner missing in the Tararua Ranges in cold, wet weather.
Alastair Shelton, 33, has not been seen since he left for a lone run on Saturday morning. He failed to turn up as arranged to meet family members for a picnic at Holdsworth Lodge.
Senior Sergeant Caroline Watson of Masterton police said 10 teams have been searching the Mt Holdsworth-Jumbo Circuit in Tararua Forest Park.
Police had also hoped to mount an aerial search but heavy rain and high winds ruled that out.
Senior Sergeant Watson said police fear for Mr Shelton's safety as temperatures in the park plummet.
"He was basically in mountain running gear - shorts and a merino top."
Mr Shelton is two metres tall with short brown hair, and was wearing black shorts, a white singlet and bright green running shoes.
Weather again delays tramper search

Alistair Levy, 54, from Palmerston North has has not been heard from since last Sunday when he sent a text message from the summit of Mt Owen, west of Nelson.
Police had hoped to resume an aerial search, but bad weather has prevented that for three days.
