A growing number of Kiwis are misspelling their own names on travel documents, risking being left stranded at airports or sent home by overseas authorities.
The problem has escalated because there are now more immigrants with New Zealand passports, ports abroad have got increasingly tougher and more people are booking holidays online.
Blair Huston, managing director of Fortis Travel in Auckland, said that at least once a day a client provided incorrect details to his agency.
It included people who didn't know how to spell their long names, missed out some of their middle names, were recently married or divorced and were not using the same name as on their passport, and people who used their middle names as their first names.
"If you turn up to Los Angeles and they go, 'Hang on, your name's not right,' they could easily - and they do - turn you around and transport you back to deport you. And that's at the airline's cost.
