Taxes are always a hot topic for anyone planning to invest, work, or emigrate abroad. Tax in New Zealand draws particular interest when New Zealand’s GST (Goods and Services Tax) is lauded by the IMF – International Monetary Fund as one of the best tax systems globally. (New Zealand Today – NZViet) In this article, we analyze how NZ’s tax system works, its strengths and weaknesses, other tax types, and the implications for Vietnamese investors or workers.

GST in New Zealand — The centerpiece
What is GST?
GST in NZ is similar to VAT in many countries but with NZ’s own unique application.
Rate & Scope
- The current GST rate is 15% applied to most goods and services in NZ. (New Zealand Today – NZViet)
- Key feature: minimal exemptions, broad coverage — nearly all consumption is taxed. (New Zealand Today – NZViet)
- Although 15% is lower than the European average (~22%), NZ’s broad base generates significant revenue. (New Zealand Today – NZViet).

Why IMF praises it
According to Professor Michael Keen (former IMF Tax Policy Director):
- A good tax must balance efficiency, fairness, and simplicity — NZ’s GST meets these criteria admirably.
- Citizens in NZ accept the tax as fair through uniform consumption taxation. (New Zealand Today – NZViet)
- Few exemptions reduce tax avoidance and loopholes. (New Zealand Today – NZViet)
Other taxes & the capital gains tax issue
Current status of capital gains tax
- Currently, NZ taxes some capital gains income, but not all types comprehensively. (New Zealand Today – NZViet)
- This leads to inconsistency: labor income is taxed under PAYE (pay-as-you-earn), while some capital gains are exempt. (New Zealand Today – NZViet)
- Professor Keen argues that in a truly comprehensive tax system, all income should be taxed unless specifically exempted. (New Zealand Today – NZViet)
Limitations & inconsistency
Exemptions for certain capital gains reduce the “comprehensiveness” and create disparity between different types of income.
Fiscal challenges – Aging population & budget pressures
- An aging population imposes rising pension (superannuation) and healthcare costs. (New Zealand Today – NZViet)
- Fewer working-age people shrink the tax base while expenditures rise. (New Zealand Today – NZViet)
- NZ’s government has flagged that raising GST is one of the technically simpler options to maintain public spending. (New Zealand Today – NZViet)
Implications for Vietnamese investors & workers
Consumer cost impact
With broad GST coverage, everyone in NZ (including Vietnamese residents) pays 15% tax on most goods and services, unless exempted.
Effect on investment & real estate
If NZ expands capital gains tax, investors (both foreign and domestic) may face higher taxes when realizing gains on assets.
Advice for prospective movers/investors
- Account for consumption tax when estimating living expenses.
- Stay updated on changes in capital gains tax.
- Leverage any tax exemptions where available under NZ law.
