A 30.2 million dollar Lotto prize still hasn't been claimed - a week on

Lotto is urging people to check tickets bought at Auckland's Albany Central Superette for the October 23 draw.

It's this year's second-biggest win - and the seventh-biggest ever.

Lotto NZ says it will take further steps to find the winners if it isn't claimed in the next few weeks.

Winners have a year to claim their prize.
