A Lotto ticket holder from Otago won $18.2 million in the Powerball First Division on Saturday night.
The winning punter bought their ticket online.
Their total prize is a combination of $18 million from Powerball First Division and $250,000 from Lotto First Division.
Three more Lotto players also pocketed $250,000 on Saturday night. Their tickets were purchased from Feilding Video Centre, Tony's Stationery and Lotto in Maungaturoto and on MyLotto to a player from New Plymouth.
Lotto says anyone who bought tickets from those stores should "write their name on the back of the ticket and check it immediately at any Lotto outlet, online at MyLotto.co.nz or through the Lotto NZ ticket-checker app".
