Punters who have a Lotto ticket for tonight's draw could win $32 million - the largest jackpot on offer so far this year.
The jackpot would also be the third-largest Powerball prize ever won in New Zealand, if it was won by a single player.
The two largest wins were a $44 million ticket sold in November 2016 in Dairy Flat, and a $33 million ticket sold in Ponsonby in Auckland in September 2013.
Lotto NZ's corporate communications manager Emilia Mazur said ticket sales were going "exceptionally well" leading up to tonight's draw.
She encouraged anyone still planning on buying a ticket not to leave it to the last minute, and instead get in early to avoid a queue.
"There's a real buzz in our stores with more people coming in to be in with a chance to win the big prize," she said.
Mazur was expecting ticket sales would reach one million before 7.30pm this evening.
HOW TO SPEND IT
Lotto has released a list of extravagant things you could do with the $32 million - after paying off the mortgage of course.
• Chowing down on the world's most expensive dessert (a $1.65m diamond-encrusted fruitcake) while listening to Lorde perform some tunes in your backyard ($300,000).
• Have all the smashed avocado you could want by buying an avocado orchard in Katikati for $1.2 million.
• How about the chance to name a beach in Auckland? A 7.65-hectare clifftop property in Waiwera has just come up for sale including access to a 450-metre unnamed beach. This slice of paradise could be yours for $15 million.
• Why not give someone the gift of independence and sponsor the breeding, training and raising of a guide dog for just $22,500.
• Buy a street and make all your friends your next-door neighbours. "Millionaire's Lane", has a nice ring to it, doesn't it?
• Love theme parks but hate the lines? Why not buy your own rollercoaster for around $2 million.
• Maybe a tropical island in the South Pacific is more your thing? You could buy Katafanga Island in Fiji for $24 million - you'll be all ready to go with a runway, water and power infrastructure.
• After winning Powerball you might feel like you could float into space, but why not actually go there? You could book a seat on a Virgin Galactic flight for just $345,000
• Put your money where your mouth is and give Dunedin's chocolate factory fundraising effort a boost. Match the already $2 million raised by the New Zealand public to keep chocolate being made in the south.
