An NZeTA lets you enter as a visitor. The conditions that come with a visitor stay are what decide whether you may work or study, and those conditions are narrow.
You cannot work
Immigration New Zealand states it plainly for visitors: you cannot work. This holds even if the work is short, unpaid, or for an employer outside New Zealand paying you overseas. If earning is part of why you are going, you need a work visa, not an NZeTA.
You can study for up to 3 months
Short courses are allowed. The limit is 3 months of study in a 12-month period. A longer course needs a student visa, and enrolling first does not change that.
Where travellers get caught out
- Attending a conference is usually fine; being paid to speak at it is not.
- Volunteering can still count as work if it displaces a paid role.
- Remote work for an overseas employer is not automatically safe — check before you assume.
If you are unsure whether what you plan to do counts as work, ask Immigration New Zealand before you travel. Being turned around at the border costs far more than the question.

More on the NZeTA
Medical treatment
If the purpose of the trip is medical treatment, Immigration New Zealand requires a Medical Treatment Visitor Visa. The NZeTA does not cover it.
NZeTA or visa?
The NZeTA covers short visits from visa-waiver passports. Longer stays, work, study beyond 3 months and medical treatment need a visa instead.
Which one do I need?
Similar names, very different rules. Which scheme applies to which destination, what each one costs, and the mistakes that come from mixing them up.
Arriving in New Zealand
Your NZeTA gets you on the plane. What comes after: eGates, biosecurity, money, driving, phones, health, safety and holidays — from official sources.
eGate at the border
eGates at Auckland, Wellington, Christchurch and Queenstown take ePassports from 59 countries and territories, age 10 and over. The NZTD is still required.
Liquids at airport security
International flights from New Zealand: liquids in carry-on in 100 ml containers, one 1-litre bag. Domestic flights have no liquid limits.
