While Aucklanders worry about their west coast beaches, there's a different kind of concern brewing on New Zealand's West Coast: the region's workers are quietly getting poorer.

The West Coast's total taxable income reached $259 million in 2024, up from $242 million in 2020. On paper, that's a 7% increase. But here's what that headline number hides: inflation over the same period ran between 20-25%. (Source: Stats NZ (LEED), taxable-income-sources)

Do the maths and the story flips. In real terms, the Coast's workers are earning roughly 15-18% less than they were in 2020. Every dollar earned buys less. Every pay cheque stretches thinner.

This matters because the West Coast isn't Auckland or Wellington, where workers can shop around for higher-paying jobs or switch industries when times get tough. The Coast's economy runs on tourism, mining, and forestry. When those sectors stall, there's nowhere else to go.

And the trajectory tells the story. Between 2020 and 2024, the region added $16.9 million in nominal income. Sounds impressive until you adjust for purchasing power. That growth doesn't cover the rising cost of groceries, petrol, power, or rent. It doesn't account for the fact that a West Coast worker's 2024 dollar is worth about 80 cents compared to 2020.

The Reserve Bank's decision to hold the OCR might be good news for mortgage holders nationwide, but for West Coast workers watching their real incomes slide, it's cold comfort. Interest rates staying flat doesn't help when your earnings can't keep pace with inflation.

Look at the longer arc: back in 2000, the West Coast's total taxable income sat at $154 million. Over 24 years, it's grown to $259 million. That's a 68% increase. But factor in two decades of inflation and the picture is far less rosy. The region's income has barely kept pace with the rising cost of living, and in the last five years, it's lost ground entirely.

This is the hidden story in New Zealand's regional economies. Headline income figures climb. Politicians point to growth. But peel back the nominal numbers and you find workers whose purchasing power is shrinking, whose standard of living is sliding backwards, whose economic reality doesn't match the press releases.

The West Coast's $259 million isn't a record to celebrate. It's a warning sign that nobody's reading.
