By the title "too many people are going to New Zealand", I assumed it was about immigration. NZ seems like a great place to migrate to but the catch is that you need an offer letter from the employer first and there aren't any employers around (at least I am unable to find one) who are gladly hiring overseas candidates.
Employers want you to be physically present at the place of job to give you a job offer, country gives work visa only when employer issues an offer letter. Not sure how that'd work?
Come with 3 months tourist visa after already arranging some job interviews online, then once there go to as many as you can & once you get an offer apply for the work visa.
