Working together to reduce international phone scam calls to New Zealand.

What it is

The original purpose of the Scam Call Prevention Working Party was to develop an industry code of practice for Network Operators to identify, verify and take action on scam calls to landlines and mobile phones. 

Subsequent to the development of the code, the Working Party meets quarterly to monitor implementation of the Code and developments in scam call prevention technology as well as to extend cooperation regarding scam call processes to agencies outside of the telecommunications industry to improve outcomes for consumers.


New Zealand, like many other countries, is targeted by off-shore based phone scammers calling or texting national landline and mobile users.

The scammers attempt to persuade anyone who answers their call, or receives their text, to cooperate in some way.

Their objective is to extract funds from the recipient by deception, and transfer it to the scammer’s bank account.


  • A Code detailing the agreed process for identifying and blocking international scam traffic targeting New Zealand customers - complete .
  • Consultation with interested parties on the draft Code - complete.
  • Implementation plan and agreed reporting metrics, if any - complete.
  • Ongoing discussion forum - underway.

Code endorsed

Following a period of public consultation and consideration of submissions received, the TCF has endorsed and published The Code and invites Network Operators to sign up to it. The Working Party will continue to meet periodically to review advances in technology that may assist in preventing scam calls and making further recommendations to the TCF Board where appropriate.
