NT Police have scaled down an air and ground search for a 50-year-old man who went missing from his home in Wadeye over last weekend.

Members from the Territory Response Group, NT Emergency Services and up to 45 local community volunteers have been conducting extensive air and ground searches for Mr Kolumboort since he was reported missing.

Local Police and community volunteers will continue their efforts to locate Mr Kolumboort.

Mr Kolumboort is described as being an Aboriginal man, approximately 175cm tall, of a slim build with grey/black shoulder length hair and a full facial grey beard. He was last seen wearing brown, red and white coloured army camouflage shorts, no shirt and no shoes.

Family members say the man is a capable bushman who knows the region.
