Both columns use the same $100,000 single PAYE vignette for 2026/27: PAYE + ACC earner levy, KiwiSaver opted out, student loan off.
Auckland and Hamilton model identical take-home because New Zealand personal income tax is nationwide IRD PAYE — no city or regional wage levy. Hamilton wins on cost of living (COL 88).
COL indexes (125 vs 88) are the practical differentiator for purchasing power when take-home ties — the same model indexes used in our New Zealand salary × city series.
What drives New Zealand metro paycheck gaps

Auckland models about $22,878 PAYE and $1,750 ACC — identical to Hamilton. KiwiSaver is $0 (opted out).
PAYE and ACC match on both sides — any ranking difference is COL, not tax.
All six metros on this hub should match take-home at every ladder rung; corridors are COL stories, not tax-nation stories.
Why the income ladder matters
At NZ$50k the modeled cash gap between these metros is $0; at NZ$200k it is $0 — both should be zero on this nationwide model.
Use the ladder to confirm identical take-home at every band before treating COL as the only relocator lever.

Cost of living vs take-home
Auckland COL index 125 · COL-adjusted proxy $60,298. Hamilton COL index 88 · proxy $85,650.

Decision guides
Inter-city move (same tax)
Focus on rent, commute, and COL (125 vs 88) — PAYE will not move the needle between Auckland and Hamilton on this model.
Job offer negotiation
Ask about KiwiSaver, bonuses, and other deductions — those change take-home more than the city name on the offer letter.
High COL destination
If relocating to the higher-COL metro (Auckland), stress-test rent against take-home — a tax tie does not automatically fund housing.
What this compare excludes
- Employee KiwiSaver contributions (opted out at 0% on this vignette)
- Student loan repayments
- Working for Families / Best Start
- Employer KiwiSaver (employer-only cost)
- Self-employed / provisional tax income
- Share-based remuneration (RSUs, options)
- Non-PAYE income (dividends, capital gains)
Myths vs reality
"Auckland has a city income tax like New York."
Auckland does not add a municipal or regional wage tax on this model. Same for Hamilton — both use nationwide IRD PAYE + ACC.
"Moving from Auckland to Hamilton changes my PAYE."
Both use the same nationwide stack — modeled take-home matches. Housing and COL (125 vs 88) change; the PAYE calculation does not.
"Auckland taxes more than Dunedin."
Cash take-home ties at $75,372 on NZ$100k. Dunedin ranks higher only because COL 85 is lower than Auckland 125 — not a different tax schedule.
"COL-adjusted take-home is my real paycheck."
It is a purchasing-power proxy only. IRD cares about taxable income and levies — not our salary × city COL index.
"ACC is higher in Auckland."
Not on this single model — both sides show $1,750 ACC at NZ$100k.
