Australia vs New Zealand: salary after tax and cost of living

Do you take home more in Australia or New Zealand?

The same salary, shown in US dollars and converted to each country at market exchange rates, so take-home is compared on the same real money.

How much tax do you pay on $80,000 in Australia vs New Zealand?

Is New Zealand cheaper than Australia, and what is your pay really worth?

On World Bank price levels (United States = 100), Australia sits at 94.2 and New Zealand at 90.8, so New Zealand costs about 3.6% less to live in. Adjusted for those prices, a A$121,232 salary in Australia has the same buying power as about NZ$127,390 in New Zealand. After both tax and cost of living, take-home on an $80,000 salary is worth about the same in each.

A 2.7 point gap built from the first dollar

$80,000 converts to A$121,232 across the Tasman in one direction and NZ$132,184 in the other. The Australian worker pays A$27,158 in income tax plus A$2,425 in Medicare levy, netting A$91,650 at an effective rate of 24.4%. The New Zealander pays NZ$33,498 in PAYE and NZ$2,313 in ACC earners' levy, netting NZ$96,373 at 27.1%.

The difference comes from the bottom of each schedule. Australia exempts a tax-free threshold and applies a low rate to the first band above it, so a chunk of every salary is taxed lightly or not at all. New Zealand taxes from the first dollar. Neither country has a large employee social contribution in the European sense: Australia's superannuation guarantee is paid by the employer on top of salary, and KiwiSaver is optional and left out of these figures. What you see is close to what you get.

The ladder flips at $150,000

Australia's lead is widest at the bottom. On $40,000 an Australian keeps 83.3% (A$50,522, about $33,339) against 80.0% in New Zealand (NZ$52,887, about $32,008). On $60,000 it is 78.1% against 75.5%. On $100,000 the gap is down to 1.8 points, 73.3% against 71.5%. Then on $150,000 the order reverses: New Zealand keeps 68.3% (NZ$169,367, about $102,504) and Australia 67.9% (A$154,336, about $101,845). The New Zealander is $659 a year ahead. In cash the Australian lead runs $1,331 at $40,000, $1,603 at $60,000, $2,153 at $80,000 and $1,848 at $100,000 before it turns negative.

The crossover happens because Australia's top marginal rate is steeper than New Zealand's. The tax-free threshold that helps a lower earner in Australia matters less and less as salary rises, while the higher Australian top band matters more. For anyone weighing a senior offer on either side, the payslip is a wash and other factors should decide.

Real verdict: a dead heat, so pick your city

Australia's price level is 94.2 and New Zealand's is 90.8, so New Zealand is 3.6% cheaper on average. Deflate the two net salaries and the result at $80,000 is $64,203 in Australia against $64,236 in New Zealand. That is a tie by any sensible standard.

The purchasing-power equivalents are similarly close. A$121,232 in Australia buys what NZ$127,390 buys in New Zealand, a little less than the NZ$132,184 that $80,000 converts to at market rates. Going the other way, NZ$132,184 in New Zealand matches A$125,795 in Australia. Neither country has a structural edge at this salary. Compare the actual job offers, the rent in Auckland against Sydney or Wellington against Melbourne, and the value of the employer's superannuation against any KiwiSaver match. Those will move the answer far more than the tax tables do. One practical wrinkle for anyone moving mid-year: the Australian tax year ends on 30 June and the New Zealand one on 31 March, so a move in the second quarter can leave you filing part-year returns in both countries.
