New Zealand High Commission Singapore
Transferring of Singapore Immigration Stamps
Once you have received your new passport you will need to have your Singapore Employment/Dependent Pass transferred into it. This will require you to visit the Ministry of Manpower (MOM) with both passports (old and new) and your green card to have your stamps transferred to the new passport.
If you are a Singapore Permanent Resident (PR) you will need to take both passports (old and new) to Singapore Immigration and Checkpoint Authority (ICA) to have your PR stamp transferred to the new passport.
