Can I get a WINZ benefit on a temporary visa?

Generally, no. People in New Zealand on a temporary visa (not a residence-class visa) are not entitled to most Work and Income benefits. There are narrow exceptions — for example, some support for people awaiting a decision on a refugee or protection claim. Once you hold a residence-class visa, most benefits additionally require 2 years of continuous residence in New Zealand before you qualify. If you are unsure of your own situation, Work and Income's eligibility pages let you check by visa type — it is worth confirming directly rather than assuming either way.
