$24 million winners won't quit day jobs

A Rotorua family has cashed in their Lotto ticket for a life-changing $24.3 million - but they're not going to quit their jobs.

The winners, who wish to remain anonymous, said they had no idea their Lotto ticket was so valuable until they stopped in at their local dairy - Springfield Superette and Lotto in Rotorua - late on Sunday afternoon.

"We had no idea our ticket had all six Lotto numbers and the matching Powerball number," one of the winners said.

"I called the family home to tell them. My wife and kids were screaming and jumping up and down in the background.

"It's a real high - we're just delighted to be winners."

The family plans to keep their lives as normal as possible, and all plan to keep working.

The $24,300,822 prize is made up of a Powerball First Division prize worth $23,800,822 and a Lotto First Division prize of $500,000.

It ranks as the fifth largest Powerball prize won in Lotto history and is the seventh Powerball First Division prize to be won in 2015.

The largest Powerball prize in Lotto history was worth $33 million and was won in September 2013 in Auckland by a self-proclaimed "Westie" from West Auckland.
