Following last night's draw (which, to reiterate, wasn't won) Powerball expanded to a jaw-dropping $32m.
And if Powerball was won on Saturday night, it would be the third-largest jackpot in New Zealand history.
A $1m Strike Must Be Won draw would also be running on the same night.
Lotto was expecting ticket sales to be even bigger, at 1.5m tickets total, for the next draw, which would eclipse last night's sale of a million tickets.
It was recommended that customers got in early to avoid a last-minute dash, Robinson said.
"We know that the last couple of hours before a draw are the busiest time for sales both in-store and online," she said.
"With $32 million up for grabs with Powerball on Saturday night, Lotto NZ recommends that players get their ticket early to miss the last-minute queues."
This year, 31 Kiwis became overnight millionaires after winning with Lotto's games, including 12 who have won big with Powerball.
In total, 906 Kiwis had become overnight millionaires with Lotto since it was established in 1987.
Meanwhile, in order of frequency, the luckiest number Lotto numbers had been 1, 7, 19, 22, 18 and 13.
