Australia vs New Zealand
Side-by-side economic and demographic comparison · 2026 data · Source: IMF & World Bank
Australia and New Zealand are close allies with deeply integrated economies under the Closer Economic Relations agreement.

New Zealand's GDP per capita is about 70% of Australia's, and many New Zealanders migrate to Australia for higher wages. Both countries have strong institutions, low corruption, and high quality of life, consistently ranking near the top of global livability indices.

Why sources report different numbers
The IMF, World Bank and United Nations each publish these series on their own release schedule. Where their figures differ, the reason is usually visible in the reference year rather than in the methodology.
| Source | Australia | New Zealand |
|---|---|---|
| IMF | $2.12T2026 | $278.64B2026 |
| World Bank | $1.80T2025 | $264.06B2025 |
| United Nations | $1.83T2024 | $260.17B2024 |
These are not the same reference year. IMF publishes 2026 and United Nations publishes 2024 — each is the latest that publisher has released, on its own schedule. A figure for a year still in progress is a projection rather than an outturn. Australia spans about 18% across 1 year; New Zealand spans about 7% across 2 years.
