After 15 years in New Zealand, I was asked to change my identity to renew my driver's licence.
I was born Tan Kim Huat, Lincoln and both my Singapore birth certificate and passport identify me as such.
Applying for my New Zealand driver's licence in 1999, I was told by the licensing agent that I was "not entitled" to use Lincoln as my first name.
The licensing agent said then that under the rules, if a foreign identification did not state which was the surname then that last name would be considered the family name.
After a lengthy exchange, she agreed to let me keep Tan as my surname - but I had to use Kim as my first name.
