Police were delivering flyers about missing woman Shelly Crooks today in Punakaiki and nearby Fox River, the area where she was last seen.
Detective Sergeant Kirsten Norton, of Greymouth CIB, said they were again appealing for sightings of Ms Crooks who has not been seen since December 22.
As well as delivering flyers they were making general inquiries with people living in the Punakaiki and the Fox River areas.
Norton said Crooks was known to have been walking local tracks but might have hitchhiked north.
She is described as 180cm tall and of medium to solid build.
