Unclaimed Funds NZ will assist in your identification and proof of address and historical employers names when the contributions were made to the compulsory NZ Superannuation savings scheme (pension fund).  

We also have digital versions of the New Zealand Electoral Roll records from the mid 1970s that have full details of your address and occupation from over 45 years ago.   

This is a valuable resource in piecing together the clues that will assist in getting a complete identifcation match so the funds can be recovered into your name and subsequently into your bank account.
