Everyone knows groceries got expensive. But here's what the national averages hide: the Rest of South Island. everything outside Christchurch. saw food costs jump $248 per person in a single year, from $15,132 in 2023 to $15,380 in 2024. That's the biggest one-year increase this region has seen since 2022.

This matters because the Rest of South Island isn't a wealthy urban centre absorbing price shocks with high incomes. It's Timaru and Invercargill, Queenstown and Gore, Dunedin and Oamaru. These are places where a family of four just watched their annual grocery bill climb by nearly a thousand dollars in twelve months.

The trajectory tells the story of the last five years. In 2020, this region spent $12,464 per person on food. By 2024, that figure hit $15,380. That's a 23.4% increase in four years. or $2,916 more per person since the start of the pandemic.

Break that down to weekly terms: a household is now spending roughly $56 more each week on groceries than they did in 2020. For a family of four, that's $224 extra at the checkout every single week. Not because they're eating more. Not because they're buying fancier food. Because the same basket costs more.

What makes 2024 particularly notable is the contrast with the year before. From 2022 to 2023, the region saw a similar jump of $1,337. But then came 2023 to 2024: just $248. On the surface, that looks like relief. Inflation slowing, right?

Except it's not relief when you're starting from $15,132. A smaller increase on top of an already inflated base doesn't make groceries affordable again. It just means they're getting more expensive at a slightly slower rate. The damage is already done.

This is the part of New Zealand where people notice. Where $248 isn't rounding error, it's the difference between paying the power bill on time or not. Where grocery inflation doesn't average out across a diverse economy because there isn't one. (Source: Stats NZ, food-price-index-regional)

The national conversation fixates on Auckland's eye-watering totals and Wellington's sticker shock. But the Rest of South Island's numbers reveal something different: sustained, relentless upward pressure on household budgets in places with fewer options and less economic cushion.

Twenty-five years of data shows this isn't a blip. From 1999 to 2024, food costs in this region have climbed steadily, with only minor plateaus. The pandemic years accelerated what was already happening. Now we're living with the result: grocery bills that have grown nearly a quarter in just four years, in the part of New Zealand that can least afford it.
