I answered the question about double dipping when you asked on the NZ Forum.
To credit flights to both NZ & SQ PPS the following fields in the booking are used:
FQTV "NZ FF No" Airpoint Dollars
FQTS "SQ FF No" $'s for PPS Status
You can either get the call centre to do or leave it to checkin to get the FQTS field added. I usually also check at the gate to make sure both fields have the appropriate FF numbers.
You mention retrospective but also just about to take a flight. So not sure where you are at. I have not needed to make a retrospective claim but no harm in calling the call centre or sending an email.
