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.
