How the maths works

Lottery odds come from combinatorics — counting how many ways you can choose a subset of numbers from a pool. The formula is:

C(n, r) = n! / (r! × (n − r)!)

where n = pool size, r = numbers to choose

For Lotto NZ, you pick 6 numbers from 140 (a pool of 40 numbers):

C(40, 6) = 40! / (6! × 34!) = 3,838,380 combinations

Each ticket covers exactly one combination, so your jackpot odds are 1 in 3,838,380 — which matches the official published odds of 1 in 3,838,380.

Does buying more tickets help?

Yes — but the improvement is smaller than you might think. Each ticket adds one independent combination to your entry. With n tickets, your jackpot odds become n in 3,838,380:

TicketsJackpot oddsApproximate cost
11 in 3,838,380~$2 USD
51 in 767,676~$10 USD
101 in 383,838~$20 USD
501 in 76,768~$100 USD
1001 in 38,384~$200 USD
Buying 100 tickets still leaves your jackpot odds at roughly 1 in 38,384 — statistically indistinguishable from 1 ticket. Syndicates can pool entries but do not change the underlying probability per ticket.

Frequently asked questions

What are the odds of winning the Lotto NZ jackpot?
The odds of winning the Lotto NZ jackpot are 1 in 3,838,380. That means for every ticket you buy, you have a 1 in 3,838,380 chance of matching all numbers correctly.
How are Lotto NZ odds calculated?
Lotto NZ odds are calculated using combinatorics — specifically the combination formula C(n,r) = n! / (r! × (n-r)!). You pick 6 numbers from 1–40, giving C(40,6) = 3,838,380 combinations. The total is 3,838,380 possible outcomes.
Does buying more Lotto NZ tickets improve my odds?
Yes — each additional ticket gives you one extra combination. If the jackpot odds are 1 in 3,838,380 and you buy 10 tickets, your odds become roughly 10 in 3,838,380, or 1 in 383,838. That said, even 10 tickets still leaves you with an astronomically small chance of winning the jackpot.
