A Wellington household buying their weekly groceries in 2024 spent an average of $293. Four years earlier, in 2020, that same shop cost $238.

The difference: $55 a week. Or $2,860 a year. That's the price of a modest holiday, a car repair, or three months of power bills.

Wellington's annual food bill reached $15,246 in 2024, according to Stats NZ's regional food price index. It's the culmination of four consecutive years of increases that began when COVID-19 disrupted global supply chains and never really stopped (Source: Stats NZ, food-price-index-regional).

The trajectory tells the story: $12,357 in 2020. Then $12,673 in 2021. A sharp jump to $13,680 in 2022 as inflation hit hard. Another leap to $15,020 in 2023. And finally $15,246 last year.

That's a 23% increase in four years. Your salary probably didn't keep pace.

What's striking isn't just the total, it's the relentlessness. There was no year of relief, no pause where prices stabilised or fell back. Every single year added hundreds more dollars to the capital's grocery burden.

For renters in Wellington, already paying some of the country's highest housing costs, this matters more than the national average suggests. When your rent takes half your income, an extra $55 a week on food isn't an inconvenience. It's a crisis point. It's the moment you start making calculations: skip the dentist, or skip buying fresh vegetables?

The data goes back fifty years, to 1975, when New Zealand was a different economy entirely. Controlled prices. Fixed exchange rates. A protected domestic market. Comparing then to now is meaningless. But comparing 2020 to 2024? That's the story of how quickly things can change.

Four years ago, $12,357 felt expensive. Pandemic-induced supply disruptions were supposedly temporary. Shipping costs would normalise. Workers would return to processing plants. Prices would ease.

They didn't. Instead, Wellington families absorbed nearly $3,000 in additional annual food costs while wages struggled to keep up and interest rates climbed.

This isn't abstract economic data. It's the difference between financial stability and constant stress. It's why KiwiSaver withdrawals are rising. Why emergency food parcels are no longer just for the unemployed. Why families who used to manage comfortably now don't.

The capital's grocery bill isn't going to fall. The question now is whether incomes will ever catch up, or whether $293 a week becomes the new floor before the next round of increases begins.
