Lotto fever is building, with a record $47 million up for grabs this week.
Officials expect an extra 500,000 tickets to be sold, with $20m to play for in Big Wednesday tomorrow and a $27m Powerball prize possible on Saturday.
The combined jackpot pool is the biggest ever, and each prize is the third largest in its respective game.
Staff at New Zealand's luckiest Lotto store, Radius Pharmacy in Hastings, have already noticed an increase in interest.
"Over the past few weeks sales have been rapidly climbing," said manager Nanette Woodham. "The momentum's there."
