Income and wealth percentile in New Zealand

What the numbers say about New Zealand.

New Zealand's median income is around NZ$72,000 per adult, with an average of NZ$95,800. Those figures place the country comfortably in the upper tier of OECD economies but noticeably below Australia, which has become the structural comparison. The economy runs on dairy, meat, forestry, tourism, and a smaller financial-services sector concentrated in Auckland and Wellington. The labour market is small, geographically scattered, and increasingly tight in the skilled trades and healthcare.

Wealth runs much higher than income would suggest. Median household net worth per adult is around NZ$343,000, more than four times the median income. Almost all of that comes from housing. Auckland property prices roughly tripled between 2002 and 2021 before levelling off, with Wellington and Tauranga following. The country had no capital-gains tax on owner-occupied housing for most of that period, which channeled household savings into property at the expense of productive investment. The wealth-to-income ratio for the country sits among the highest in the OECD.

The brain drain to Australia is the structural fact New Zealand has not solved. Tens of thousands of working-age New Zealanders move across the Tasman each year, attracted by wages 20 to 40 percent higher in equivalent jobs and easier access to housing, especially in the trades, healthcare, and engineering. The net loss particularly hits the 25-to-35 cohort, which removes the higher-earning younger workers from the domestic income distribution. Migration from the Pacific, Asia, and increasingly the UK partially offsets the outflow, but the skill mix often does not match what leaves.

Geographic income differences are sharper than the small population suggests. Auckland holds the corporate, finance, and tech labour market. Wellington runs the public sector and a meaningful technology cluster. Christchurch has rebuilt steadily since the 2011 earthquakes. The South Island outside Christchurch and Queenstown, and the regional North Island, run materially below the national median, often with thin labour markets dependent on a single industry.

Two themes shape the next decade. The 2024 government has rolled back some of the 2018 to 2023 housing-affordability measures, which may reignite price growth. And the dairy export base faces persistent pressure from environmental rules and from declining Chinese demand, the largest single market.
