Lotto officials are searching for a person in the NSW Hunter Valley who is yet to cash in a winning $15 million ticket.

Almost two complete days have passed since the winning combination for the latest Oz Lotto draw was revealed, resulting in a single ticket securing the division one prize.

The ticket was purchased at Greenhills Newsagency at the Stockland Shopping Centre in East Maitland north of Newcastle.

Because the winner has not registered with The Lott Members Club, there is no way for officials to reach out, meaning the prize can only be claimed if the winner approaches a newsagency or contacts Oz Lotto directly.

The winning numbers in the latest Oz Lotto on Tuesday were 44, 46, 39, 34, 7, 15 and 3, while the supplementary numbers were 24, 19 and 13.

A staff member at the newsagency confirmed it was the biggest prize they had ever sold, and they hoped the winner would come forward.

“We’ve sold division one winning entries in the past, but this is the biggest prize so far,” Tiarna Perry said.

“We’re so excited! Everyone has been coming in to check their tickets, wondering if it’s them or if we’ve found them yet.”

Khat McIntyre, a representative from The Lott, advised anyone who believes they might have bought a ticket for the draw to thoroughly check their entries, as it could potentially transform their life in the most amazing way.

“We’re astonished that the holder of the mystery ticket hasn’t yet come forward. They might be commuting to work today, completely unaware that they’ve won $15 million,” she remarked.

“Consider the possibility that you are the multi-millionaire we are trying to find. It’s safe to say any plans you have for the year would be wonderfully altered.”
