More than a thousand hours have been spent searching for Raymond Finnie, without success.
The 74-year-old North Canterbury man hasn't been seen since September 25, although his car has been found on Whitecliffs Road.
An extensive search of the area around his car has been completed and police are now reviewing their search area.
Flyers have been sent out to all local letterboxes and they want everyone in the Whitecliffs area to check their sheds or outhouses.
