No. Next question?

By

To be fair, 1News does say the answer is “no”, in compliance with Betteridge’s Law of Headlines

So, with a spread of wins across MyLotto and in-store purchases this year, do online tickets or in-store ones have a higher chance of winning?

Lotto’s line on this is also straightforward: “Your chances of winning Lotto stay the same regardless of where you purchased your ticket.”

At the end of the story is this line: The Lotto draw is live on TVNZ1 at 8pm tonight.

Watching the Lotto draw should really be the answer to a lot of these questions. With scratch-and-win or computer draws you might hope there was a mistake in the programming or the distribution of cards, but with the lotto draw? Look at the balls tumbling in the transparent washing-machine thing. Do they look as if they know where you bought your ticket? Do they look as if they care?

Another way to look at this: suppose there genuinely was some way to get an edge in  your Lotto chances and beat your neighbours. If you want secret advice like that, the web page of the country’s most popular news source is not going to be the place to find it.

Why do you want to know?

By

Stuff has a headline: Supermarkets say groceries are actually cheaper here than in Australia and UK

The first point to make here is that the comparison is of a basket of products chosen by Foodstuffs NZ.  It’s … not impossible… that a basket chosen by an Australian or British retailer might give a different result.

The second issue is that the comparison was of prices before GST/VAT. Australia and the UK don’t impose sales tax on some of the items in the basket but NZ does. Since the difference between PakNSave and Aldi Australia was about 7%, the impact of tax on the comparison on the comparison is pretty big. Comparing the pre-tax prices makes NZ prices look lower. Is this appropriate? It depends on why you want to know.

If you wanted to know whether moving to Australia would make your groceries cheaper, then you’d want the actually existing prices that include sales tax.  If you wanted to know whether the evil NZ supermarket duopoly was exploiting helpless Kiwi families, you might want the pre-tax prices, since that’s where the hypothetical price-gouging would hypothetically be happening.

Foodstuffs are clearly focused on the evil supermarket duopoly question (taking the “Nay” side) so it does make sense for them to look at pre-tax prices.
