Posting again as i couldn't edit the previous reply.
They wouldn't if they do it, the amount they make from the EOI selection pools will be gone and obviously they have staff members who need to be paid every week.
Each month on an average there are 1200 selections happening from the EOI pool and if we consider the cost of the Applications (EOI& ITA) it gives them almost 3500 (onshore/offshore varies) in total, so it's 3500*1200= 4.2 Million/Month) excluding the cost of NZQA, Medical/X-Rays, Postal services, and people hire LIA for their applications (which creates/sustain employment) so it brings a lot of money in NZ and goes to governments in the form of Taxes) .
There are only two solutions I can think of:
1. Increase the Salary Criteria and/or the Points (and many people would not be able to file for residency and that would keep their total numbers down/close to the government directive) and many people (especially students who have come here and spent huge amounts) would not be happy with this decision.
2. Increase the staff capacity just to deal with SMC applications (but if INZ starts giving residency to all the applicants (for example 80-90% would qualify and would be genuine to get approved), would shoot up their annual numbers and that's not in align with the Government directives).
None of the above two are happening anytime soon, and cosnidering the new chnage to bring in ANZSCO 4,5 skill employment to become eligble to apply for SMC if you earn 25 NZD/hour, would bring in more number of applications in EOI pools and ITAs, the only thing we can do is to pray to get lucky someday.
