A lucky punter who bought a Lotto ticket in Timaru is now $7.25 million richer.

The ticket, sold at the Countdown on Church St, gives the winner $7m from Powerball first division and $250,000 from Lotto first division.

It is the second big win this month, following a Tauranga winner taking home $5.5m million earlier in the month.

Three people from Auckland and Wellington will also be celebrating tonight after winning $250,000 each with Lotto first division.

These tickets were sold at Pak'N Save on Lincoln Rd in west Auckland, New World in Newlands, Wellington, and the third was bought online.

Lotto said in a statement that anyone with a winning ticket should write their name on the back and check it immediately at any Lotto outlet, online at mylotto.co.nz or through the Lotto NZ App.
