“We’re both shocked to our core. It’s going to take a while to sink in, and I don’t think it will start to feel real until we see it in the bank,” the winners, who wished to remain anonymous, said after claiming the prize.
Last Saturday, a $17.2m prize was claimed by the winner who bought their ticket from New World Whitby in Porirua.
The bumper prize is made up of a $17m Powerball win and $200,000 from a five-way split of First Division.
It is the ninth Powerball multimillionaire this year.
