Picture a family in Timaru. Every Saturday, they do the same grocery shop: meat for the week, fresh vegetables, milk, bread, school lunches. This year, that weekly shop costs them $294. Last year, it was $289. The year before, $264. In 2020, it was $240.

That's the reality behind RNZ's report that soaring bills are forcing households to cut back. South Island families are now spending $15,305 a year on groceries. a figure that's climbed every single year since the pandemic began. (Source: Stats NZ, food-price-index-regional)

The numbers tell a story of accumulation. Last year's increase was modest: $241, or about $4.63 a week. But zoom out, and you see what's really happened. Since 2020, the annual South Island grocery bill has risen $2,796. That's $53.77 every single week, year after year, compounding.

This is why households are freezing their spending. It's not one dramatic price shock. it's five years of groceries quietly eating a bigger slice of every paycheck. For a family earning the median South Island household income, groceries now consume a larger percentage of take-home pay than at any point in the past two decades.

The trajectory is relentless. In 2021, the bill jumped to $12,766. In 2022, it hit $13,735. By 2023, it was $15,064. This year: $15,305. Each year feels manageable in isolation. Put them together, and you see why people are cutting back on everything else.

What makes this particularly brutal is the timing. These increases hit hardest during the exact years when interest rates were climbing, rents were surging, and power bills were jumping. Groceries weren't the only cost rising. they were just the most unavoidable one. You can delay replacing your car, skip the holiday, cancel the streaming service. You can't skip feeding your kids.

And here's what the $294-a-week figure doesn't capture: it's an average. For families with teenagers, or households in more remote South Island towns where transport costs inflate prices further, the real number is higher. For someone shopping at a budget supermarket, buying home brands, skipping meat twice a week, it's lower. But everyone, regardless of how carefully they shop, is paying more than they were.

The freeze in household spending isn't irrational. It's the only rational response to five years of watching your grocery bill climb while your income struggles to keep pace. When food costs you an extra $2,796 a year compared to 2020, something else has to give. For South Island families, it already has.
