Australia's wedge splits into income tax 24.9%, employee social security 0% and employer social security 6%; New Zealand's into 21.1% / 0% / 0%.

Verdict
On the OECD tax wedge for a single average worker, New Zealand taxes labour more lightly than Australia — a 8.1% smaller wedge as a share of total labour cost. But the wedge is a blunt comparison: it models one standard worker, ignores your actual income, family and deductions, and says nothing about what the taxes fund. The composition matters too — a country can have a similar wedge built from very different mixes of income tax versus employer contributions.

Frequently asked questions
Does Australia or New Zealand have the lower tax wedge?
New Zealand has the lower tax wedge of the two: 21.1% of labour cost versus 29.2% for Australia — a gap of about 8.1% of total labour cost for a single average worker. Both are measured against the OECD average of 34.9%. These are modelled averages, not personal tax.
Which keeps more take-home pay, Australia or New Zealand?
New Zealand leaves the worker with more of their gross wage: a net personal average tax rate of 21.1% means they keep about 79% of gross, versus 75.1% in the other country. Note this "net rate" excludes employer social security, which still adds to the total wedge.
Why is the employer social-security difference between Australia and New Zealand important?
Employer social security is part of the tax wedge but never appears on the payslip: it raises the cost of employing someone without raising gross pay. Australia charges 6% of labour cost in employer contributions versus 0% in New Zealand. A high employer wedge means a worker on the same net pay costs the employer much more.
Should I compare Australia and New Zealand on the tax wedge alone?
No. The tax wedge is a model of an average single worker at 100% of the average wage — it ignores your income level, brackets, family status, deductions and what those taxes buy (healthcare, pensions, schooling). Use it as a directional signal, read each country's full page, and consult a tax adviser before relocating. Not tax advice.
