I have read ~50 threads and lots of links but I'm still confused. There is a lot of contradicting information on here.

When leaving Switzerland and going to a Non-EU/Non-bilateral agreement country can I claim back my AHV (1st pillar) contributions as well as my BVG (2nd pillar)? Am I right in saying that nationallity is not a factor here, it only depends on where I am going? (eg. UK citizen moving to NZ)

I am trying to get a rough idea of how much this would be. Is there an easy way to estimate what this would amount to? (I'm not sure which numbers to look at on my Lohnausweiss etc. as there are lots of columns and different abbreviations.)

Please only respond if you are certain you know what you're talking about. I have read threads with completely contradicting information in them already.
Thanks for your help.

No, it will be paid to you monthly after retirement.

Only second and third pilastri can be withdrawn when PERMANENTLY leaving the country (should you return, you must pay them back in in full!)

Any chance you know of a link or something official that says that? There are a few threads with links that don't seem to work. Several people on here have said that they have claimed their AHV back when leaving for a Non-EU/Non-bilateral agreement country. But then several other people have said it's not possible and no one seems to have an official link to corroborate what they say.

Found this:

"77. As mentioned in Step 2 the Pillar 1 pension funds accrued in the Swiss social security system can only be paid
out to you when you leave Switzerland if you are a national of a country which does not have a reciprocal
social security agreement with Switzerland (see Appendix G) and you are not moving to an EU State. If you
are eligible to have the social security fund paid out you should complete the claim form, which can be
obtained from the Swiss Compensation Office in Geneva, at the time of your departure."

So, if you are a UK national, the answer is no.

Perfect! That's exactly what I was looking for. So it looks like I will get it (NZ citizen) and my husband (UK citizen) won't.
