New Zealand's latest millionaire is yet to come forward to claim their $22.2 million prize.
The winner of Saturday's Lotto haul bought their ticket in Ashburton.
As of this morning, the prize has yet to be claimed, a Lotto spokeswoman said.
The winning ticket was sold on MyLotto and is made up of $22 million from Powerball first division and $200,000 from Lotto first division.
It is the biggest Powerball prize this year and the fourth time the game's top prize has been struck so far in 2016.
It is also the biggest win from a ticket purchased online, surpassing a Hokitika family's $15.7 million win in 2013.
The prize jackpotted to $22 million after Wednesday night and it is ranked the seventh-biggest Lotto win in New Zealand.
