Real wages in New Zealand are below their 1992 level. Labour productivity is higher.
New Zealand’s real wage index is lower at the end of 2025 than it was in 1992. Over the same 33 years, labour productivity in the goods-producing sector rose 18%. Labour productivity in services rose 60%. The divergence between what New Zealand workers produce and what they are paid for it has widened in every decade since the Labour Cost Index began.
Much of the public conversation about wages since 2021 has been framed as a post-COVID problem — inflation outpacing pay rises, the cost of living outrunning the payslip. The COVID years did compress real wages sharply. But the 1992 to 2025 data says the compression is a 33-year pattern, not a three-year shock. Real wages briefly matched their 1992 peak in 2019 and 2020. They have never meaningfully exceeded it.
Stats NZ’s Labour Cost Index has been tracking salary and ordinary-time wage rates since the June 1992 quarter. The producers-side Labour Productivity series covers every year from 1978. This article compares both against the Consumers Price Index over the 33 years for which the LCI exists.
Nominal wages doubled. Prices more than doubled. Real wages fell.
Indexing to 1992 = 100:
| Year | Nominal wages | CPI all groups | Real wages |
|---|---|---|---|
| 1992 | 100.0 | 100.0 | 100.0 |
| 2000 | 113.1 | 114.9 | 98.5 |
| 2005 | 126.7 | 129.8 | 97.6 |
| 2008 | 139.7 | 142.8 | 97.8 |
| 2015 | 158.9 | 161.0 | 98.7 |
| 2020 | 174.7 | 173.3 | 100.8 |
| 2024 | 200.2 | 210.1 | 95.3 |
| 2025 | 204.9 | 216.1 | 94.8 |
Nominal wages roughly doubled over 33 years. Consumer prices grew slightly faster. The ratio has never meaningfully deviated from its 1992 level, except briefly through the low-inflation end of the 2010s.
The trough is 2023 at 94.4. The peak is 2020 at 100.8. The entire range, top to bottom, across 33 years, is 6.3 points.
Labour productivity rose through every regime. Wages did not.
Over the same period, Stats NZ’s labour productivity index moved substantially:
| Sector | 1992 | 2000 | 2008 | 2015 | 2024 | Change 1992 → 2024 |
|---|---|---|---|---|---|---|
| Goods-producing industries | 100 | 115 | 120 | 124 | 118 | +17.7% |
| Manufacturing | 100 | 115 | 128 | 130 | 126 | +25.6% |
| Service industries | 100 | 120 | 137 | 148 | 160 | +60.0% |
All three productivity series grew. Real wages did not. Over the 33 years from 1992 to 2024, the gap between goods-producing labour productivity and real wages widened by about 22 percentage points. Against services productivity, the gap widened by roughly 65 percentage points.
Services productivity is the largest mover but also the measure most sensitive to methodology. A portion of measured services output is calculated from inputs, which builds productivity gains into the definition. The goods-producing comparison is the cleaner one. Even on that comparison, a worker in 2024 produced roughly 18% more per hour than a worker in 1992, while earning roughly 5% less in real terms.
The divergence is not a post-COVID story
The 2022 and 2023 inflation episode does show clearly in the data. Real wages fell from 100.8 in 2020 to 94.4 in 2023, a 6.3% decline in three years. That decline is the COVID-era cost-of-living shock most commentary focuses on.
But the same series was already below its 1992 level in every year from 1993 through 2018. The COVID shock compressed real wages further; it did not create the gap. The earlier table shows a real-wage reading of 97.6 in 2005, 97.8 in 2008, 98.7 in 2015. The floor has been flat. The cost-of-living problem is older than the current political cycle is prepared to treat it as.
Peak matters — real wages briefly matched 1992 only during 2019 and 2020
Looking at the top three and bottom three years in the real-wage series since 1992:
| Top three real wage years | Index (1992 = 100) |
|---|---|
| 2020 | 100.8 |
| 2019 | 100.5 |
| 1992 | 100.0 |
| Bottom three real wage years | Index (1992 = 100) |
|---|---|
| 2023 | 94.4 |
| 2025 | 94.8 |
| 2024 | 95.3 |
Thirty of the 33 years since 1992 have had real wages below the 1992 reading. Only three years equalled or exceeded it — 1992 itself, 2019 and 2020. No other year in the series made it back to the starting line.
Where the productivity went — the labour share of GDP
If workers produced more but earned less, the share of national income going to labour must have fallen. The Stats NZ quarterly GDP(I) tables publish compensation of employees as a share of total GDP income. The series in the warehouse runs from 2012:
| Year | Compensation of employees | Gross operating surplus |
|---|---|---|
| 2012 | 43.8% | 43.3% |
| 2015 | 42.9% | 44.0% |
| 2017 | 42.2% | 44.7% |
| 2020 | 44.0% | 47.7% |
| 2024 | 44.4% | 43.2% |
| 2025 | 43.2% | 44.2% |
Over the 13 years the warehouse can see directly, labour’s share has moved within a narrow band of 42.2% to 44.4%. The 2020–2021 COVID bump reflects the Wage Subsidy Scheme flowing through compensation of employees; the 2017 trough preceded COVID. There is no clean downward trend within this window.
The 33-year wage-productivity gap is therefore not primarily explained by a further fall in the labour share since 2012. The mechanism in the most recent decade is something else. Candidates include compositional shift from higher-productivity goods sectors into lower-productivity services, measurement conventions in services productivity, within-sector wage growth lagging within-sector productivity, or timing around the 2022 and 2023 inflation shock.
The longer labour-share decline, from roughly 60% of NZ GDP in the early 1980s to the 42–44% band seen now, is documented in the 2019 Tax Working Group final report, in RBNZ Bulletin research, and in Treasury productivity work. It is not reproducible from this warehouse because Stats NZ’s quarterly GDP(I) series in the current release begins in 2011. Pre-2011 labour-share data lives in Stats NZ Infoshare under older methodology, and is a clear follow-up target.
What the data settles
- Real wages in New Zealand are lower at end-2025 than in 1992. The real-wage index stands at 94.8 against 100 for 1992.
- Labour productivity rose in every published industry aggregate over the same 33 years. Goods-producing +18%, manufacturing +26%, services +60%.
- The wage-productivity gap predates COVID and the 2022 inflation shock. Real wages were already below 1992 levels in 30 of the 33 years in the series. The COVID episode widened a pre-existing gap; it did not create it.
- The COVID-era compression is real and large. Real wages fell 6.3% between 2020 and 2023, the steepest three-year fall in the series.
- The labour share of GDP has been flat at 42–44% over 2012–2024. If the wage-productivity gap has widened over that window, the mechanism was not a further compression of labour’s share of total income. It was something else, discussed above.
What the data does not settle
- Whether this is uniquely a New Zealand story. A wage-productivity divergence has been documented across most developed economies since the late 1980s, though its magnitude differs by country. A proper cross-country comparison against Australia, Ireland, Norway and the wider OECD has not been run here and is the natural follow-up piece.
- The mechanism. The data shows a divergence. It does not isolate how much is caused by measurement (services productivity is partly input-counted), how much by compositional shift (from higher-wage manufacturing to lower-wage services), how much by bargaining-power and labour-institutions change, and how much by the long decline in real interest rates that lifted capital incomes. All four hypotheses are consistent with the shape shown here.
- What a counterfactual regime would have produced. Whether wages would have kept pace with productivity under different tax, labour-market or trade policy is unanswerable from aggregate series alone.
Methods
Labour Cost Index series retrieved from Stats NZ Infoshare, All Sectors Combined × All Salary and Wage Rates × All Industries and Occupations Combined, base June 2017 quarter = 1000. Data covers 1992 Q4 through 2025 Q4. Consumer Price Index from the Stats NZ Consumers Price Index quarterly release, all groups for New Zealand. Industry productivity series from Stats NZ Aotearoa Data Explorer, dataflow PRD_PRD_001, annual labour-productivity index (year ended March), aggregates for goods-producing industries, manufacturing, and services. Labour share computed from Stats NZ GDP(I) quarterly current-price series, compensation of employees over total GDP income, quarterly values summed to annual. Annual alignment uses calendar-year averages for quarterly series against year-ended-March productivity readings; this introduces a small timing mismatch (≤3 months) but does not affect point-to-point comparisons over multi-year horizons.
