Immigration New Zealand says visa holders in New Zealand are being contacted by people pretending to be from Immigration New Zealand.
They are demanding payment from people to avoid deportation for various reasons, including incorrectly completing an arrival card and a failed police check.
The fraudsters often demand that money be paid into a Western Union account. They will often have some details of the person they are speaking to, such as their name, date of birth or address.
Immigration New Zealand says the fraudsters' caller ID comes up with 09 914 4100 or 0508 558 855.
