An anonymous reward has been offered in a bid to solve the disappearance of a gold miner who went missing on the West Coast over two years ago.
Hugh Charles McAllister, from Kumara, went missing in January 2010 and was last seen leaving for his gold claim on the Greenstone River.
The 70-year-old's ute was found by his son near the gold mine on 26 January, five days after he was last seen.
Crimestoppers chief executive Lou Gardiner says the $25,000 reward is a significant amount for its type in New Zealand and may help someone come forward.
Mr Gardiner says police are keeping an open mind about what happened to Mr McAllister and his family is searching for closure.
