A family in Gisborne, shopping at the same New World they've always used, buying the same basics they bought five years ago. Their annual grocery bill: $15,443.

That number isn't an outlier. It's the average for every household across the Rest of the North Island in 2024, from the Bay of Plenty to Northland to Taranaki. (Source: Stats NZ, food-price-index-regional)

Here's what makes this figure brutal: households are slashing discretionary spending, putting off car repairs, skipping takeaways, cancelling subscriptions. Everything is negotiable except the grocery bill. You can defer a new couch. You can't defer dinner.

Five years ago, in 2020, that same family was spending $12,615 on groceries. The increase: $2,828. That's $54 extra every single week for half a decade.

The trajectory tells the story. 2021: $12,926. A modest jump. 2022: $13,992. The cost-of-living crunch arrives. 2023: $15,362. The biggest single-year leap. 2024: $15,443. Growth finally slows, but only to $81 for the year.

That $81 increase is the smallest annual rise since the pandemic began, but it's still an increase. The bill never goes backward. It only climbs more slowly.

What $15,443 actually means: that's $297 a week. For a two-person household, it's $148 each. For a family of four, it's $74 per person per week, before you've paid rent, power, petrol, or put anything into savings.

This is the bill that's crowding out everything else. When economists talk about households cutting back, this is what they're cutting back to fund. The grocery shop is no longer discretionary spending. It's the cost you pay before you decide what you can afford.

And here's the kicker: this data covers the Rest of the North Island, regions where housing is supposedly more affordable than Auckland or Wellington. The trade-off was always: lower rents, longer commutes, smaller job markets. But if your grocery bill is $15,443 a year regardless of where you live, that trade-off just got worse.

The Reserve Bank is watching household spending freeze, waiting for inflation to ease. But inflation easing doesn't mean prices fall. It means they rise more slowly. That Gisborne family's bill isn't going back to $12,615. It's staying at $15,443, maybe creeping to $15,500 this year.

This is the new baseline. The number that shapes every other financial decision a household makes.
