The $26 million lottery winner who vowed to return to his job at a supermarket has quit.

Trevor, who kept his surname secret, from the small town of Te Kauwhata in Waikato bet a television presenter all his winnings that he would return to work as a checkout operator at Huntly Countdown at 5am the next day.

But, unsurprisingly, he didn't show and hasn't been back since.

"Nothing is going to change," the 34-year-old told Fairfax on the day of his big win.

"At the end of the day my bank balance is [longer than my] phone number, but I love my job."

But it appears Trevor is too busy with other, more important, tasks such as buying a high performance Holden ute, worth $70,000, and splashing out on a car for his mum.

After going public with his win, Trevor quickly went into hiding to avoid media attention.

His dad Kevin says Trevor won't be making any big purchases until he's out of the spotlight.

A Huntly Countdown spokeswoman told media Trevor had quit his job but still keeps in touch.
