Lotto is searching for the winner of a $10.2 million prize which has gone unclaimed for almost a week.
The winning ticket was sold on Saturday at Whitcoulls The Base in Hamilton, but nobody has come forward.
Lotto NZ senior corporate communications manager Kirsten Robinson said most big winners keep their Lotto tickets in their purse or wallet.
"You never know where this winning ticket could be sitting," she said.
Anyone who purchased a ticket from Whitcoulls The Base is encouraged to write their name on the back of the ticket and check it at any Lotto outlet.
