Here's the calculations for New Zealand in USD:
Income tax: 34% total (top marginal rate of 39%).
Leaving $133k.
Other taxes (GST~VAT 15%, city rates, high petrol excise, etcetera) will easily take another $10k. Interest on your home is not deductible (NZ has very few deductables). People earning six figures will often pay for private health insurance and medical fees on top of the socialised healthcare - maybe another few thousand.
