Is it that easy for me to get New Zealand status?

Domestic education and work experience are useless in New Zealand, unless you go to New Zealand to study for a master's degree in the same major and then find a related job after graduation. With a job offer, you can get all aspects of immigration scores.

Another way is for your sister to let your parents immigrate first. If you are not over 30 years old after your parents, you can immigrate as your parents' lineal blood relatives.
