What are the advantages and disadvantages of becoming a New Zealand citizen?

The prerequisite for joining New Zealand citizenship is that you have obtained New Zealand PR (permanent resident visa) for five years, of which the first three years have lived in New Zealand for not less than 183 days (this is the so-called immigration supervision). Judging from the landlord's problems, it is estimated that the landlord is only in a state where he can apply for immigration. Once the application is successful, he can get a PR visa and a permanent round-trip visa after three years (provided, of course, that he lives in New Zealand every year 183 days). The difference between a permanent round-trip visa and New Zealand citizenship is that you have no right to stand for election in New Zealand. You still hold a passport from China, and you are from China. Then take this visa to live in China without any inconvenience, and you can live in New Zealand at any time. If the landlord gets a New Zealand passport and lives in China, you are a foreigner in China, and you will have visa trouble every year. The landlord mentioned welfare benefits, which sounds like he wants to know about welfare benefits in China, but I don't know. As for the welfare of living in New Zealand, it is certainly good and multifaceted. Give a few examples of people's livelihood. In New Zealand, women are free from pregnancy, check-up and delivery (at their own expense in private hospitals), and once a child is born, there is a weekly milk powder subsidy. Seeing a doctor in New Zealand is divided into clinics and hospitals. Generally, minor illnesses are solved in clinics, so you need to pay tens of dollars plus a little medicine fee (because the government will subsidize the medicine fee, so you only need to pay a small part). Once your illness rises to the point of going to the hospital, the government will pay the bill. It is free for children to go to school in New Zealand until high school. Of course, you can also choose a private school at your own expense. University tuition can apply for student loans from the government, and the government will also provide living expenses every week. The loan is interest-free and the living expenses need not be repaid. There is a pension after 65. . . . . .
