Police say they cannot confirm whether missing North Shore man Denver Chance drove to the coastal town of Waihi or not.
Chance has not been seen or heard from in 11 days since he drove south along Auckland's Southern Motorway.
It emerged on Wednesday there had reported sightings of his red Nissan Skyline in Waihi, while a Facebook user posted on a page seeking help to locating Chance that they may have seen him in the local New World supermarket.
However, Detective Senior Sergeant Megan Goldie said these possible sightings could not yet be confirmed.
