What is New Zealand's green card?

In New Zealand, the identity certificate similar to the green card function is called "permanent sign-back".

That is, immigrants who have lived in New Zealand for more than half a year within two years can obtain permanent visas.

A green card is what people usually call it. It is a proof that foreigners live legally and permanently in New Zealand and can enjoy the rights enjoyed by most New Zealand citizens. Like ordinary visas, it is attached to the passport. After getting this permanent residence visa for two years, you can apply for a permanent return visa. With this permanent return visa, you can leave and land in New Zealand at any time without any time limit, and you don't have to apply for any New Zealand visa anymore. In fact, that thing is called PR, which is often referred to as permanent residency. You can apply for membership after staying in New Zealand for more than two years.
