Search for missing Auckland woman Carissa Avison focuses on Woodhill Forest

Carissa Avison has been missing since Thursday.

Police are focusing on Woodhill Forest on Auckland's west coast in the search for an Auckland woman.

Carissa Avison, 21, was last seen last Thursday, and police are concerned for her safety.

Detective Sergeant Iain Chapman said her "actions are out of character".

"[Search and rescue] teams are working in the forest area near the corner of Coast and Grass Track roads," he said.

Police have previously said that Carissa got a ride from Holder Place to Coast Rd in Muriwai, arriving about 11am on January 26.

CCTV footage showed Avison at a Hunting and Fishing store in Rosedale about an hour before.
