This is a link to the Search facility results, showing old posts of anything to do with LTBVs.  Without going through all the posts, I can’t see if they’ll be of any use to you and I see that you have been involved in a lot of them anyway.  This is a link, previously posted by Glenda, to the NZIS’ site which relates to LTBVs .

Have you got any specific questions you can put up here?  There’s not that many people on here who’ve immigrated via the LTBV and are still posting on here, but you may get lucky.
