The plain fact at the beginning of this thread is true, and has been stated many times before on this forum.
To be selected at the next draw, as the quotas are set at the moment, an applicant needs 100 points minimum WITH a job offer, or 140 points minimum WITHOUT a job offer.
This doesn't mean that it is impossible to get Residence without a job offer. Read the many postings of forum members who have had their CO interview and been approved.
However, a higher level of proof of skills NZ needs (the 140 points) is required of those people, because INZ is taking a gamble on each of those people being impressive enough to land a job when they get to the country.
