A lotto number generator is a tool that produces a random set of numbers for you to play, instead of you choosing them by hand. In New Zealand the official version is built straight into Lotto — it is called a Dip — and dozens of free websites and apps offer the same thing. What none of them can do is improve your chances of winning. This guide gives you example random lines and free tools to generate your own, then explains what these generators really do, how the official Dip works, and why a randomly generated line and a line you pick yourself have exactly the same odds.
Want numbers straight away? The box below shows three example lines a generator produces for the main Lotto draw — six numbers from 1 to 40, plus a Powerball from 1 to 14. For a working tool you can run yourself, use the official Dip built into MyLotto, where you choose how many lines you want and it fills them at random, or a reputable free generator such as Powerball.net’s Power Dip generator. Whichever you use, the numbers are random, so the box below is just as valid a pick as any of them.
Example Random Lines
| Line | Lotto numbers (1–40) | Powerball (1–14) |
|---|---|---|
| 1 | 4, 11, 19, 23, 32, 38 | 7 |
| 2 | 2, 9, 16, 27, 34, 40 | 12 |
| 3 | 6, 13, 21, 25, 29, 36 | 3 |
What a lotto number generator actually does
A generator picks numbers at random from the valid range for the game you are playing. For the main New Zealand Lotto draw, that means choosing six numbers from 1 to 40. Most generators can also fill in the extra numbers for the add-on games:
- Lotto: six numbers from 1 to 40 for each line.
- Powerball: one extra number. Since the first draw under the new format on 16 September 2026, NZ Powerball is drawn from 1 to 14 (it used to be 1 to 10).
- Strike: the first four numbers drawn, in the order they come out of the machine. A generator can pick and order these too; see how Strike works for the detail.
That is the whole job. A generator makes a selection; it does not enter you in a draw, remember past results, or weight the numbers in any way. Each number in range has the same chance of being chosen as any other.

The official random pick: Lotto NZ’s Dip
You do not need a third-party website to get random numbers. When you buy from Lotto NZ, you can ask the computer to choose for you, and the result is called a Dip. You will see it on tickets as a Lucky Dip (random Lotto lines) or a Power Dip (random Lotto lines with Powerball added). A Dip simply fills your lines with computer-picked numbers; choosing a Dip changes who picks the numbers, nothing else about your ticket.
You can buy a Dip at any authorised retailer or online through MyLotto, where the “auto-fill” or “Dip” button does the same thing a random generator does. Some players choose a Dip for speed, and some because they assume the computer knows something they do not. It does not: Dip numbers are randomly generated and have no connection to earlier draws.
Do random picks improve your odds?
No. The odds of winning are fixed by the maths of the game and nothing about how you choose your numbers can move them. For the main draw, the chance of matching all six numbers for Division 1 is 1 in 3,838,380 per line. Adding Powerball lengthens that to roughly 1 in 53.7 million per line since the September 2026 change. You can read more about the odds of winning Lotto in New Zealand, but the short version is that no tool shortens them.
Two beliefs drive most of the faith people put in generators, and both are wrong:
- “Some numbers are due.” The draw machine has no memory. A number that has not appeared for months is no more likely to come up next time than one drawn last week. Treating a long absence as a signal is the gambler’s fallacy.
- “Hot numbers are on a roll.” A number that has appeared often recently is not more likely to keep appearing. Every combination of six numbers from 1 to 40 is equally likely in every single draw.
Because the outcome is pure chance, there is genuinely no strategy for winning — a point the official safer-gambling guidance makes plainly. If you want a realistic look at what does and does not work, see our rundown of popular ideas on how to win Lotto in NZ.
Myth vs Reality
| Myth | Reality |
|---|---|
| A generator can find numbers that are “due” to appear. | Each draw is independent and the machine has no memory — no number is ever overdue. |
| Random picks win more often than numbers you choose. | Odds are identical — 1 in 3,838,380 per line for Division 1 — however you choose. |
| The “best” generator gives you better numbers. | Every fair generator is equally random; none can raise your chance of winning. |
| Hot numbers that appear often are more likely next time. | Past frequency does not predict future draws; every combination is equally likely. |
| Picking your own numbers lowers your odds. | It does not change your odds, but popular picks like birthdays can mean sharing a prize. |
Random pick versus choosing your own numbers
If the odds are identical, does it matter whether you use a generator or pick your own? For your chance of winning, no. But there is one measurable difference, and it works slightly in favour of random picks.
Many people choose numbers that mean something to them — birthdays, anniversaries, house numbers — which crowds their picks into the 1 to 31 range and into familiar patterns. Researchers at the University of Otago, analysing a large Lotto New Zealand dataset, found that players pile into a small set of popular picks: straight lines and diagonals traced across the playslip, skip-counting sequences such as 5, 10, 15, 20, 25, 30 and 1, 2, 3, 4, 5, 6, and famous number sets. Because so many players choose these same combinations, they concluded that any given combination has the same chance of being drawn, but a randomly generated ticket has a higher expected payoff: if your numbers do come up, you are less likely to be sharing the prize with a crowd of other winners who picked an identical popular line.
So a generator will not win you more often, but it tends to spread your numbers across the full 1-to-40 range and avoid the most over-chosen patterns. If you prefer the ritual of your own lucky numbers, that is perfectly fine — just know you are trading a slightly higher prize-sharing risk for the sentiment, not giving up any chance of winning.
Using a free online generator safely
Free generators on other websites and in app stores are harmless as novelty tools: they produce six numbers and nothing more. The important thing to understand is what they cannot do.
- A third-party generator cannot enter you in the draw. To actually play, you still have to buy a ticket from an authorised New Zealand retailer or through the official MyLotto site or app.
- Treat any site with suspicion if it asks for payment to “generate winning numbers”, promises numbers that are “more likely” to win, or offers to buy you a ticket from overseas. No generator can predict a draw, and offshore ticket-buying services are not the licensed New Zealand operator.
- You never need to hand over personal or payment details just to see a set of random numbers. If a generator asks for them, close the page.
In practice, the safest free generator is the official one: the Dip button on your ticket or in MyLotto gives you the same random numbers with none of the risk.

Frequently Asked Questions
Is there an official Lotto number generator in New Zealand?
Yes. Lotto NZ’s random pick is called a Dip. At a retailer or on MyLotto you can let the computer choose your numbers for you — a Lucky Dip for standard Lotto lines, or a Power Dip when Powerball is added. It is the same idea as any online generator, except it is tied directly to a real ticket.
Where can I generate NZ Lotto numbers for free?
The official free option is the Dip on MyLotto or at any Lotto retailer, which fills the number of lines you choose at random. Several reputable third-party sites and apps also generate NZ Lotto and Powerball lines for free, and the box near the top of this page shows what a typical result looks like. Any of them is fine for picking numbers, but only an official ticket from MyLotto or an authorised NZ retailer actually enters you in the draw.
Do random picks win more often than numbers I choose myself?
No. The odds are identical whether the computer picks or you do — 1 in 3,838,380 per line for Division 1. The only edge a random pick has is that it tends to avoid popular patterns like straight lines and birthday-style numbers, which can reduce the chance of sharing a prize if you win, not the chance of winning itself.
Are free online lotto number generators safe to use?
As a way to produce random numbers, yes — they just display a selection. But they cannot enter you in a draw, and you should avoid any site that charges to “reveal winning numbers”, claims its numbers are more likely to come up, or offers to buy overseas tickets on your behalf. To play for real, buy from an authorised NZ retailer or MyLotto.
How many numbers does an NZ Lotto generator produce?
For the main draw it picks six numbers from 1 to 40. If you include Powerball it adds one more number from 1 to 14 (since the 16 September 2026 change), and for Strike it selects the first four numbers in the order they are drawn.
Can a generator find “hot” or “due” numbers?
No. Each draw is independent and the machine has no memory, so no number is ever “due” and a recent streak means nothing for the next draw. Any generator that claims to track hot or due numbers is selling a myth; the numbers it gives you are simply random.
