The search is on for a Christchurch Lotto player who won $5.2 million last Saturday with a ticket bought at Hornby Mall.
The person won Saturday's Powerball but has still not claimed the prize almost a week later.
"While most winners are quick to check their tickets, it's not unheard of for big winners to take a bit of time to claim their prize," said Kirsten Robinson, senior corporate communications manager at Lotto NZ.
"The winner could be holding onto their winning ticket while they let the good news sink in - or they may not even know yet just how much that little yellow ticket is worth."
With a winning Powerball ticket hiding somewhere in the city, Lotto NZ is urging Christchurch Powerball players to dig out their tickets and get checking.
