A household in Taranaki buying the same basket of groceries they bought in 2020 is now paying $15,443 a year. Not for luxuries. For the basics: bread, milk, vegetables, meat. The things you need to feed a family. (Source: Stats NZ, food-price-index-regional)

This is what the food price index looks like when you zoom out from monthly movements and percentages to what families actually spend over twelve months. In the rest of the North Island, that figure stood at $12,615 in 2020. By 2024, it had climbed to $15,443. The difference: $2,828.

That's not a monthly increase. That's the extra cost of eating for an entire year. It's two months of rent in some regional towns. It's a second-hand car. It's what many families used to save.

The trajectory tells the real story. In 2021, the annual cost rose by $311. In 2022, it jumped $1,066. In 2023, another $1,370. Last year, the pace finally slowed: an increase of just $81. But the damage was done. Families in places like Hawke's Bay, Manawatū, and Taranaki are now budgeting around a grocery bill that's 22% higher than it was four years ago.

The rest of the North Island covers everywhere outside Auckland and Wellington. These are regions where wages tend to run lower and options for shopping around are fewer. You can't hop between three competing supermarkets when there's only one in town.

For context, $15,443 a year breaks down to roughly $297 a week. That's before you've paid rent, filled the car, or turned on the heater. It's just the cost of keeping food in the fridge.

The slowdown in 2024 offers little relief when you're starting from a base that's already climbed nearly $3,000. Prices aren't falling. They're just rising more slowly. Families aren't getting their money back. They're adjusting to a new normal where a weekly shop costs what a fortnightly shop used to.

This is the hidden cost of the last four years. Not the headline inflation rate. Not the quarterly CPI. The actual dollar figure a household in regional New Zealand now needs just to eat.
