OK, thank you for this, I know I can always count on ENZ for more accurate info than INZ
Hopefully we won't have to worry, it looks like an ex-student of mine will bring the birth cert with him in the end of the week, if all goes to plan!! However, this does put me at ease to know that those 6 months should still be available to us (nowhere in the law does it state number of applications, the contrary). No problem with collecting evidence, we now make an effort to do so, not like in the beginning!
