How does New Zealand avoid immigration prisons?

First, after getting PR, I will stay in New Zealand for two and a half years in a row. If I have a full-time job, the time seems to be reduced. Then you can apply for a permanent visa at the immigration office. With this visa, you can go back to New Zealand at any time without sitting in an immigration prison.

Second, after completing PR, if you stay for five consecutive years (it seems to be three years), you will directly change your nationality and become a citizen. Of course, there will be no immigration supervision, but you will have to apply for a visa to China in the future.

Yes, the details of immigration supervision are as follows.

New Zealand ordinary investment immigrants: the investment will be maintained for 4 years, and they will live every year for the next three years 146 days;

New Zealand high-investment immigrants: the investment will last for 3 years, and they will live for 44 days every year in the next 2 years;

New Zealand ordinary entrepreneurial immigrants:
