The National Lottery says the holder of a €1m winning Lotto ticket from New Year's Day has not yet turned up to claim the jackpot prize.
The winning ticket was sold in Tesco in Ballybeg in Waterford on 9 December.
Each year around €20m worth of prizes go unclaimed, around 2% of sales, which go back into special draws at different times of the year.
Each winner has 90 days from the day of the draw to collect a prize.
The draw on New Year's Day was a 'Millionaire's Draw'.
