You have summed up the situation, that nobody is telling you what you would like to know.
I'm replying that many, many people down the years have this same experience. It's
not just you - and by 'you' I mean anyone who is at the same stage. And however much I sympathize with your feelings (and those of all the others), I can't make it be, or seem, any different. I'm just saying what IS, because there's no point in pretending, and SOME people find it helpful to have the information. Don't shoot the messenger. INZ is an arm of the NZ government, and the government can change the rules and tweak the quotas and alter the processing procedures however they like, and the way those actions affect the applicants' emotions adversely doesn't have to concern them (the government) at all, because the applicants aren't their voters. Yes, the system is tougher now, and yes, fewer people are getting through.
You're implying, I think, that I don't empathize with posters who come here wanting information and explanation. This isn't a JOB. I'm a member of the public, sharing what knowledge I've gathered of New Zealand and INZ, in my spare time. You're back, six years after your first go, and here I still am, answering the same kind of questions to at least the sixth cohort of applicants since. You won't find emoji hearts and kisses, though.
