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

What it is

The purpose of the Phone Blocking Working Party is to develop an industry code of practice for network operators to identify, verify and take action on scam calls to landlines and mobile phones.

Public Consultation

The TCF has developed a draft Code for Scam Call Prevention (“The Code”) and is now issuing it for public consultation.

You are invited to examine the draft Code and provide your feedback.

If you wish to make a submission, please note that the closing date is 5.00 pm, Monday 21 May 2018.

Please send your submission via email to or post it to the NZ Telecommunications Forum, P O Box 302469, North Harbour, Auckland 0751.

Please note that unless stated otherwise, all submissions will be regarded as public and will be published on the TCF website.


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.

  • Implementation plan and agreed reporting metrics, if any.
