Lotto isn't the only game in town — it's just the hardest one to win

Lotto NZ switched Powerball over to a 14-ball draw on 13 September, the first change to the number pool in almost two decades. The old 10-ball version went out with one last must-be-won jackpot, and the new format takes over from here.

Here's what that change actually means, and how it stacks up against the other big options if you're chasing a major prize in New Zealand: Lotto, Strike, and three of the country's best-known charity lotteries.

Powerball just got harder to win

Before this week, matching all your numbers for Powerball Division 1 was a 1 in 38,383,800 shot. With four more balls in the mix, that's now 1 in 53,737,320. Lotto NZ isn't hiding the trade-off. The jackpot itself got bigger, the starting pool rising from $4 million to $5 million and the cap from $50 million to $60 million, and a new Division 8 means more small wins across the board. Almost all of that growth is small, lower-tier prizes. The shot at the actual jackpot just got about 40% longer, for the same ticket price.

Base Lotto and Strike

Play just Lotto, no Powerball, and matching all six numbers for Division 1 sits at 1 in 3,838,380. That's roughly 14 times better than the new Powerball odds, which tracks: it's a smaller ask, six numbers picked correctly instead of six numbers plus an extra ball drawn from a separate pool.

Strike, the other Lotto add-on, asks you to match the first four numbers drawn, in the exact order they come out. The odds of that are 1 in 2,193,360, slightly better than base Lotto's Division 1, for a very different kind of bet.

Now the charity lotteries

This is where the numbers stop looking anything alike. Charity lotteries don't sell an unlimited number of lines into a recurring draw. They sell a fixed, capped batch of numbered tickets for one draw, and every ticket in that batch has a real shot at the main prize.

Coastguard's current lottery, Lottery 128, has 15,000 tickets on sale, for a main prize valued at $250,000: a choice of an Audi, a boat, a travel package, or cash. One ticket wins. That's 1 in 15,000.

The Heart Foundation's current lottery, No. 164, is bigger: 290,000 tickets, with a $1.2 million home in Kinloch as first prize. That puts the odds at 1 in 290,000, still nowhere near Lotto Division 1, let alone Powerball.

Northern Rescue's Extreme Lottery, which funds rescue helicopter and search and rescue services across Northland, Auckland and the Coromandel, is priced at $100 a ticket: 15,000 tickets, for a single prize package valued at over $400,000 (an Extreme 746 Game King boat, a Ford Ranger WolfTrak, and gear). Also 1 in 15,000.

This isn't a fair fight, and it isn't supposed to be. Lotto and Powerball are built to run forever on small stakes and a jackpot that keeps growing until someone claims it. Charity lotteries do the opposite: a hard-capped batch of tickets, a fixed draw date, and a prize that gets handed out regardless. Different mechanics, different economics.

But if the question is simply "what are my actual odds of winning the top prize," the charity lotteries aren't just a bit ahead of Lotto and Powerball. They're a different order of magnitude ahead, by a factor of a few hundred to nearly two thousand.
